16. The letters pH stand for ´power of hydrogenª. In simplest terms, pH indicates the acidity of a solution. The pH scale has a particular quirk: the acidity increases ó the pH number decreases. A solution of pH 2 is more acidic than a solution with a pH of 3, but less acidic than a solution with a pH of 1. The broad scope of pH values includes a significant range of solution types. Values below pH 7 are acid, values above pH are alkaline.
17. Atoms vary greatly in weight, but they are all about the same size. The smallest and lightest atom is the hydrogen atom. It consists of 1 proton and 1 electron. The largest and heaviest atom in nature is the uranium atom. It has 92 protons, 146 neutrons, and 92 electrons. An atom of uranium weighs more than 200 times as much as an atom of hydrogen. However, a uranium atom is only about 3 times as large in diameter as a hydrogen atom.

18. Astronomers predict that in 5,000,000,000 years the center of the sun will shrink and become hotter. The surface temperature will fall slightly. The hotter temperature of the center will increase the rate at which hydrogen changes into helium, and the amount of the sun's energy will also increase. The outer regions of the sun will expand to 50 million kilometers. The sun will then be a red giant star and the earth's temperature will become too high for life.
19. The sun gives off many kinds of radiation besides visible light and heat. These radiations include radio waves, ultraviolet rays and X-rays. Ultraviolet rays consist of waves of light that are shorter than the waves of violet light on the visible spectrum. They are invisible to the human eye. The atmosphere absorbs much of this radiation. The sun gives off more ultraviolet rays and X-rays during periods of violent activity than during calm periods.

10. We know very little about the early history of life on Earth for two reasons. First, the life forms were soft, and had no skeleton or other hard parts, so they didn't form fossils when they died. Secondly, at first life existed entirely in the sea, so that any remains that were left were on the sea floor, which has been recycled completely several times.

11. Hales (1677ñ1761) began the study of the functional activity of plants, and his work was the most important in that department until the 19th century. He measured the amount of water taken in by the roots and given off by the leaves, comparing this with the amount of moisture in the earth and showing the relationship of one to another. His most important contribution for botanical physiology was perhaps his demonstration that the air contributes something to the building up of the substance of plants.

3. When a liquid is heated, its molecules move more and more quickly until the liquid turns into a gas or vapour. When a liquid is cooled, its molecules move less quickly until they take up fixed position and the liquid freezes into a solid.
4. Certain alloys resist corrosion because they are noble metals. Other alloys resist corrosion because a protective film develops on the metal surface. This passive film is an oxide which separates the metal from the corrosive environment.
5. Curium is dangerous because of its radioactivity, and tests on animals have shown that if it gets into the body it concentrates in the bone marrow where its intense radiation destroys red blood cells. It also collects in the liver, but from there it is rapidly excreted.
6. Bile's digestive properties result from bile salts, which are manufactured by the liver from a fatty substance called cholesterol. Bile salts break up globes of fat into tiny particles that digestive enzymes in the small intestine can attack.

7. If you will be taking this medicine in large doses for a long time, do not stop taking it without first checking with your doctor. Your doctor may want you to reduce gradually the amount you are taking before stopping completely.
8. Before a drug is given to the general public, it is carefully tested in the laboratory to see how it works. Then it is tested on laboratory animals to see if it is effective, what doses are needed and if there are side-effects. Finally, it is tested on volunteers.
9. The exact way that this medicine acts against cancer is not known. However, it seems to interfere with the growth of the cancer cells, which are eventually destroyed. Since the growth of normal body cells may also be affected by this medicine other effects will also occur. Some of these may be serious and must be reported to your doctor.

10. Placebos work because of the mind's ability to affect the body. Many studies have shown that when a doctor offers any treatment, people expect it to help, and that expectation itself can aid healing. Also, through a mind-body mechanism placebos trigger the release of endorphins, the body's mood-elevating, pain-relieving compounds.
11. Medicines may be injected to produce an effect on the entire body. Medicines are often injected when people are unable to take medicines by mouth or other routes when a very rapid effect is needed or for medicines that are not absorbed well when given orally.

12. The beginning of alkaloid chemistry is usually considered to be 1805 when F. Serturnar first isolated morphine. He prepared several salts of morphine and demonstrated that it was the principle responsible for the physiological effect of opium. The term ´alkaloidª, which was first proposed by the pharmacist Meissner, in 1819, and means ´alkali-freeª, is applied to basic nitrogen-containing compounds of plant origin.
13. All new medicines must undergo thorough testing before being approved for use. Before a new medicine can be tried in humans it must undergo extensive testing in the laboratory, to assess its safety and biological activity. This ´preclinicalª development stage may last as long as three or four years. Then clinical trials in human volunteers determine if a medicine is safe and effective, at what doses it works best and what side effects it causes.

14. Antibiotics may be given by injection, orally, or topically. When they are given orally, they must be absorbed into the body and transported by the blood and extracellular fluids to the site of the organisms which cause infection. When antibiotics are administered topically, such absorption is really possible, and they then exert their effect only against those organisms present at the site of application.
15. When a liquid is heated, the energy taken in causes its particles to move more rapidly. Some particles gain enough speed to break through the surface of the liquid and jump out of the liquid. Some particles escape altogether from the liquid. These particles are said to have evaporated. If you keep on heating a liquid, its particles move so fast, and are so far apart, that they form bubbles of gas within the liquid itself. At this point the liquid is said to be boiling.

5. According to Aristotle, the basis of all material objects was to be found in four qualities: heat, cold, moisture, and dryness. These qualities could combine to form the four elements: earth (cold and dryness), water (cold and moisture), air (heat and moisture), and the fire (heat and dryness). By altering the proportions of their qualities, these elements could be changed into each other.

10. What made it difficult for early investigators to understand the nature of air was the belief that it was an element, so the idea of its being a mixture of gases was quite alien to the established way of thinking. Yet, in the Middle Ages, Leonardo da Vinci (1452ñ1519) had noted that air must contain something essential to life and that when this had been used up then neither a candle flame nor a living animal could survive.
11. Sometimes two elements are rather similar. For instance, nickel and iron are. Both nickel and iron are whitish metals that are attracted by magnets. Both are about equally hard, equally heavy, and equally hard to melt. But they are not the same in all ways. Iron rusts easily, while nickel does not. If fine pieces of iron are dropped into acid the iron will dissolve and the acid will turn yellow. If fine pieces of nickel are used instead, they will dissolve but the acid will turn green.

12. Alchemy, a combination of chemistry, magic and philosophy, tried to find or prepare substances which would turn cheaper metal into gold and silver and which would also cure any human ailment and prolong human life. In its fullest sense alchemy was a philosophical system containing a complex and rudimentary science, elaborated with astrology, religion, mysticism, magic, theosophy and many other constituents. Alchemy dealt not only with the mysteries of matter, but with those of creation and life. It sought to harmonize the human individual with the universe surrounding him.

“ÂÍÒÚ˚ ‰Îˇ ÍÓÌÚÓθÌÓ„Ó Ô‚Ӊ‡ Í –‡Á‰ÂÎÛ 1 1. Atoms are the smallest stable units of matter. They consist of subatomic particles. There are dozens of different subatomic particles, but the most important for understanding chemical properties are: protons, neutrons, and electrons. Protons and neutrons are similar in size and in mass, but protons bear a positive electrical charge, and neutrons are electrically neutral. Electrons are much lighter than protons and bear a negative electrical charge. Atoms normally contain equal numbers of protons and electrons. The number of neutrons does not affect the properties of an atom, other than its mass.
2. The idea of atoms, as the ultimate indivisible pieces of matter, goes back to the times of Ancient Greeks. In the fifth century BC Democritus gave atoms their name which means ´indivisibleª. But the real development of the atomic model dates from the end of the 18th century, when chemists began the modern investigation of the properties of the elements. But the final acceptance of the ´atomic hypothesisª came only in the first decade of the 20th century thanks to the work of A. Einstein.
3. Titanium, when pure, is a lustrous, white metal. It has a low density, good strength, and has excellent corrosion resistance. It is ductile only when it is free of oxygen. The metal, which burns in air, is the only element that burns in nitrogen. Titanium is resistant to dilute sulfuric and hydrochloric acid, most organic acids, chlorine gas, and most chloride solutions. Natural titanium is very radioactive after bombardment with deuterons. The radiations are mostly 258

positrons and hard gamma rays. Titanium is dimorphic. The hexagonal alpha form changes to the cubic beta form very slowly at about 880∞C. The metal combines with oxygen at red heat, and with chlorine at 550∞C.
4. Magnesium is a silvery-white, fairy tough metal. Magnesium is the eighth most abundant element in the earth's crust. Sea water also contains plenty of magnesium. Normally a layer of oxide, MgO, coats magnesium and protects it from air and water. Magnesium does not react with water to any significant extent. Magnesium metal dissolves readily in dilute sulphuric acid. This is in contrast with calcium, immediately below magnesium in the periodic table, which does react slowly with cold water. Magnesium metal does however react with steam and hydrogen gas (H2). Calcium is more reactive with air than magnesium. Magnesium tarnishes slightly in air. The metal burns in air with a very bright white flame. Magnesium is an important element for plants and animals. The adult daily requirement of magnesium is about 0.3 g.

5. Ozone is a special form of oxygen. Ozone is oxygen that has undergone rearrangements from the normal diatomic molecule, O2, to a triatomic form, O3. Common diatomic oxygen and triatomic ozone obviously differ in molecular structure. This variance is responsible for slight differences in the physical and chemical properties of the two allotropes. Ozone is chemically more reactive than oxygen. Ozone has characteristic sharp odour. Unlike normal oxygen, ozone is very toxic. It affects the respiratory system. The concentration of ozone is not uniform over all parts of the globe. The production of ozone depends on ultraviolet radiation.
6. Sulfur is the tenth most abundant element in the universe. In 424 BC, the tribe of Bootier destroyed the walls of a city with a mixture of coal, sulfur, and tar. Sometime in the 12th century, the Chinese invented gun powder which is a mixture of potassium nitrate (KNO3), carbon, and sulfur. Early alchemists gave sulfur its own alchemical symbol which was a triangle at the top of a cross. Through experimentation, alchemists knew that the element mercury combined with sulfur. Sometime around 1777, Antoine Lavoisier convinced the rest of the scientific community that sulfur was an element and not a compound. This non-metal is pale yellow in appearance, soft, light. It burns with a blue flame that emits a peculiar odour (sulfur dioxide, SO2). Sulfur is insoluble in water but soluble in carbon disulfide.

Nearly all are marine plants. In this group there are no very simple primitive forms. The brown algae are most numerous on rocky coast, where they are often exposed to the tides. Brown algae are found in many regions, but are especially abundant in the cold temperature and arctic waters. All brown algae are multicellular plants. Photosynthesis in them, as in other plants, results in the formation of sugar.
2. The existence of atoms was first established experimentally at start of the 19th century when J. Dalton carefully analyzed the masses of substances that combined with one another. The internal structure of atoms was determined by a succession of experiments in the late 19th and early 20th centuries. J. Thomson showed that matter was built from electrons and in due course, mass and negative charge of the electron were determined.
3. *The names ´cationª and ´anionª were coined by M. Faraday in the 19th century, when he was establishing the effect of electric currents on solutions of ions. He found that there were two types of ions that traveled in opposite directions in the presence of electrodes ó one toward the positive electrode and the other toward the negative electrode. Ion is the Greek word for ´travelingª, ´catª is derived from the Greek for ´downª and ´anª from the Greek for ´upª.

4. *Chemical energy is a form of energy that is stored inside a chemical. The energy is released or absorbed during a chemical reaction. Common sources of chemical energy are wood, petroleum, natural gas and coal. When these substances are burned, the chemical energy that is stored inside is changed into heat and light. Fossil fuels are valuable sources of chemical energy. These fuels formed from the remains of animals and plants that died hundreds of thousands or millions of years ago. Over the years they were compressed with layers of mud and sand.
5. *Tellurium was discovered by Muller (1740ñ1825). Muller had amassed a collection of minerals during his trips around Europe and was particularly intrigued by one mineral which came from a mine near Zalatha. It had a metallic luster. For three years Muller researched the new material which he called metallum problematum or aurum paradoxum because of its mysterious nature. Finally he concluded that the mineral was a compound of gold with an element, which was unknown. Muller sent a sample of a mineral to the eminent German chemist Klaproth (1743ñ1817) in Berlin, who investigated it, confirmed that it was a ´newª element, obtained a pure sample and called it tellurium.

6. *Radioactivity was accidentally discovered in 1896 by Becquerel (1852ñ1908). The French physicist found that when a mineral sample was placed on a photographic plate that had been wrapped in black paper, the light-sensitive emulsion became dark. Becquerel recognized that the mineral itself was emitting a powerful form of radiation that penetrated the black paper. Further investigations revealed that the rays were coming from the element uranium, a constituent of the mineral. Becquerel applied the term ´radioactivityª to this spontaneous emission of radiation by certain elements. Subsequent research led to the identification of two major forms of radiation: alpha and beta.
7. The 20 amino acids that are found within proteins convey a vast array of chemical versatility. The precise amino acid content, and the sequence of those amino acids of a specific protein, is determined by the sequence of the bases in the gene that encodes that protein. The chemical properties of the amino acids of proteins determine the biological activity of the protein. Proteins not only catalyze all (or most) of the reactions in living cells, they control virtually all cellular process.
8. Scientists from Siberian research institutes have created AIDS and hepatitis B vaccines. Tomatoes have been used. The edible vaccines have already been tested on animals and have given positive results. The immune system of mice that ate transgenic tomatoes became stronger. The entire world has been working on the creation of such an edible vaccine for more than ten years but no one has 263

Laser light moves in one direction and contains only one or two colours. Lasers can do many things. They can ´readª compact disks. They can cut through metal. They can send messages through space. They can create three-dimensional images in the air.
2. Acetaminophen is available in tablets, and in liquid form or in the form of drops. It can be purchased without prescription. It must be dissolved in a glass of water. This reduces its time in the stomach and possible gastric irritation. However, it contains much bicarbonate and should not be taken daily over long periods.
3. There are 15 vitamins, and most of them must be supplied by food. Vitamins are needed in very small amounts by the body, but when they are not provided, a person can get a deficiency disease. Vitamins should not be used as ´tonicsª. There is a distinct possibility that the indiscriminate use of vitamin preparations may sometimes lead to overdosage, a problem that has arisen in resent years. For example, overdosage of vitamins A, D, or K may result in a serious disease.

Their bodies will contain several tons of carbon, nitrogen, phosphorus and other valuable elements that the trees over their lifetime have extracted from the atmosphere and the ground. But in this form these valuable substances are locked away and are beyond the reach of any other plant or animal. The cellulose and lignin, which make up most of the bulk of a tree, are extraordinary stable substances. Only two kinds of living things can reduce them to the basic elements ó bacteria and fungi.

4. Antibiotics e.g. penicillin can destroy bacteria by killing them directly or by preventing them multiplying. Anti-fungals commonly used for infections of the skin and mouth (e.g. clotrimazole and miconasole) work by disrupting infected cells. Other medicines work by killing abnormal cells, for example some anticancer drugs directly target and kill harmful cancer cells.

5. Classifying plants is not an easy task. No two individual plants are exactly alike but closely related plants may be very much alike. Long experience, good judgment and an eye for the form of plants are essential for good work in plant classification. The six areas of classification from smallest to largest are species, genus, family, order, class, and phylum.
6. The leaf blade is veined with sap-conducting tubes with thick-walled supporting cells. The blade consists of an upper and a lower layer of closely-fitted epidermal cells, including specialized paired guard cells that control the size of tiny pores for gaseous exchange and the release of water vapour.
7. Sulfur was known in ancient times. The Greek poet Homer mentioned ´pestaverting sulfurª nearly 2,800 years ago! Sulfur is pale yellow in appearance non-metal, soft, light, with a distinct odor of rotten egg. It burns with a blue flame emitting a peculiar suffocating odor (sulfur dioxide, SO2). Sulfur is insoluble in water but soluble in carbon disulfide. It displays three allotropic forms: orthorhombic, monoclinic and amorphous. The orthorhombic form is the most stable form of sulfur. Monoclinic sulfur exists between the temperatures of 96∞C and 119∞C and reverts back to the orthorhombic form when cooled.

8. Water has a simple molecular structure. It is composed of one oxygen atom and two hydrogen atoms. Each hydrogen atom is covalently bonded to the oxygen via a shared pair of electrons. Oxygen also has two unshared pairs of electrons. Thus there are 4 pairs of electrons surrounding the oxygen atom, two pairs involved in covalent bonds with hydrogen, and two unshared pairs on the opposite side of the oxygen atom. Oxygen is an ´electronegativeª or electron ´lovingª atom compared with hydrogen. Water is a ´polarª molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge (δ−) near the oxygen atom due to the unshared pairs of electrons, and partial positive charges (δ+) near the hydrogen atoms.

5. The first alloys were made in prehistoric times, soon after people first learned about metals. These alloys were made of metals that were plentiful ó copper, tin, lead and zinc. Bronze, the first alloy containing about 90 percent copper and 10 percent tin, was found to be much harder than either copper or tin. It is made by casting, which involves melting the metals, pouring them into a mold and letting them harden.
6. The ancient Greeks were the first to search for rational explanations for life; their ideas were based on a mixture of observation, guesswork and superstition, and focused on the question of what separated life from non-living matter. Greek philosophers were the first to propose that all matter consists of very small particles called atoms. No further progress was made with the development of this atomic theory of matter until the 18th and 19th centuries, when the experimental evidence needed to support the theory began to accumulate.

To prevent this odor, they treated the tissues with a variety of substances that became known as antiseptics.
2. The kinetic theory of gases was first proposed by D. Bernoulli in 1738. He was inspired by the work of R. Boyle who had discovered in the middle of the 17th century that when gas is compressed the volume of the gas changes in inverse proportion to the pressure. Bernoulli realized that the relationship between the temperature of a gas and its pressure could be explained in terms of the kinetic energy (energy of motion) of the little particles in the gas. But he was ahead of his time. In those days most thought that it was related to the presence of a kind of fluid which moved from one substance to another. Bernoulli's version made no impact at all on science at that time.

3. The similarity of beryllium and aluminium caused quite a bit of trouble to the author of the periodic law D. Mendeleev. The fact is that precisely of this similarity, in the middle of the 19th century beryllium was considered to be a trivalent metal with an atomic weight of 13.5. Mendeleev asserted that atomic weight of beryllium had been incorrectly determined, that the element was not trivalent but divalent and possessed the properties of magnesium. On the basis of this he placed beryllium in the second group, having corrected its atomic weight to 9.
4. Many medicines need to be stopped slowly, with regular checks from a doctor to ensure there are no health problems. Furthermore, you should not stop taking your medicine even if you feel better, as your doctor may have prescribed it to prevent recurrences of your condition, e.g. migraine and asthma medicines. If you experience any side-effects or the medicine doesn't seem to be working as it should, contact your doctor or pharmacist as soon as possible. He or she may be able to prescribe or recommend a different but equally effective medicine.

5. All human beings and human activities are imbedded in and depend upon the ecosystems of our planet, which are the machinery of nature, the machinery that supports our lives. Without the services provided by natural ecosystem, civilization would collapse and human life would not be possible. One of the services that ecosystems provide is control of its quality. The oxygen that animals depend upon is produced by plants. In addition, a great variety of microorganisms control the concentration of the other major gaseous constituent of the atmosphere, nitrogen, that makes up almost 80 per cent of the air we breathe.
6. Leaves are the food factories of a plant. The raw materials they use are of the simplest carbon dioxide, water and a few mineral ingredients. The first, a gas, is all around them in the air and they absorb it through tiny pores in their surface. Water, and the minerals dissolved in it, is collected by the roots from the ground in which the plant grows. The agents within the tissues of the leaves that process these raw materials are small grains containing the green substance, chlorophyll. Powered by the energy of the sun, this is able to combine these elements and produce starches and sugars, the food from which the plant builds its various tissues. The process is called photosynthesis.

7. Three gas laws apply directly to physiological problems at altitude. Boyle's law, which states that the volume of a mass of gas is inversely proportional to the pressure exerted, providing the temperature remains constant, explains expansion of intestinal gases, and the earaches that can be caused by trapped gases in the middle ear, sinuses and mastoid cells. Henry's law, that the weight of a given gas dissolved in a liquid varies greatly with the partial pressure of the gas, explains how exposure to the low pressure at altitudes may release nitrogen gas normally held in the blood in solution and thus produce bends symptoms. Dalton's law states that in a mixture of gases the part of the total pressure or partial pressure exerted by each gas is proportional to its volume percent as altitude increases, oxygen continues to constitute 21% of the atmosphere, but the decreased pressure of the upper atmosphere and consequently of the oxygen results in reduced oxygenation of the blood. Physical well-being and the ability to think and to reason are therefore inherently dependent upon the pressure of oxygen breathed.

Two methods are used: chemical reduction and electronic reduction. The former consists of heating the metal chloride with calcium under an atmosphere of argon gas. The latter involves passing an electric current through a mixture of the metal chloride and sodium chloride.
2. It is recommended that all children receive the chickenpox vaccine at 12 to 18 months of age. Because the chickenpox vaccine is relatively new, it is not known how long the vaccine protects a person against chickenpox. However, some people who have had the vaccine appear to be protected for as long as 20 years.
3. This medicine works best when there is a constant amount in the blood. To keep the amount constant, do not miss any doses. Also, it is best to take the doses at evenly spaced times day and night. If you miss a dose of this medicine, take it as soon as possible. This will help to keep a constant amount of medicine in the blood. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double dose.

4. It is recommended that a physician be consulted if pain is not relieved within 5 days. For geriatric patient, it may be advisable that these medications not be used for longer than 5 days at a time, because such patients may be more susceptible to adverse renal effects.
5. Plants have always been of interest to man. It has been shown that at an early period men distinguished and named the kinds of plants they encountered. As civilization developed, men began to arrange and record their knowledge of plants, and in this way botany began. Men's interests were manifold; as time went on, they concerned themselves not only with the kinds and names of plants but also with their structure, their mode of life, their chemical composition, the functions of their parts and their reproduction.
6. Leaves, one way or another, produce all the foods a plant needs for growth. The methods used by the vast majority of them to do this require that they should be flat in order to capture sunshine, and thin to allow gases and water vapour to diffuse freely throughout them. The arrangements of leaves on the stem may be one in which the leaves are in a spiral, or alternate pattern, or two leaves may be attached at the same node, providing an opposite arrangement.

7. There is scarcely a plant on earth that man has not tried to use as a medicine, as well as a food. In ancient times men tried out different plants to see which ones helped cure certain diseases. At first they may have used plants with a strong odor or a bitter taste. Perhaps they thought that those plants with a bad taste or unpleasant smell would drive out the evil spirits believed to cause disease. Early men probably watched animals to see what plants the animals ate, especially when animals were sick. By trial and error, over the ages, men came to use thousands of plants as remedies for their ills.
