- 181: Suicide
- ... out. Most people argue that nothing justifies the taking of someone's life. Yet what makes life so valuable? Why do people cling to it so? All we consist of is a bunch of carbon atoms, bound together to form an exoskeleton, organs, and tissue. In this light, there really is not much to life. Out of the 5 billion who inhabit the planet, very few of them shall emerge to ...
- 182: Acid Rain 2
- ... half of the emissions of this gas in the world. When sulphur dioxide gets in the atmosphere, it oxidizes to first form a sulphate ion. It then becomes sulphuric acid as it joins with hydrogen atoms in the air and falls back down to earth in the form of acid rain, snow, or fog. Oxidation occurs the most in clouds and especially in heavily polluted air where other compounds such as ...
- 183: Acid Rain 6
- ... approximately half of the emissions of this gas in the world. When sulphur dioxide reaches the atmosphere, it oxidizes to first form a sulphate ion. It then becomes sulphuric acid as it joins with hydrogen atoms in the air and falls back down to earth. Nitric oxide and nitric dioxide are also components of acid rain. Its mainly caused by exhaust fumes. Like sulphur dioxide, the nitrogen oxides rise into the ...
- 184: Quarks
- ... basic components if matter Quarks are believed to be the fundamental constituents of matter, and have no apparent structure. They are the particles that make up protons and neutrons, which make up the nucleus of atoms. Also, particles that interact by means of the strong force, the force that holds parts of the nucleus together, are explained in terms of quarks. Other baryons are explained in terms of quarks(1985 Quarks ...
- 185: Atomic Bombs
- ... nuclei results in an explosion of tremendous force and heat, accompanied by a blinding light. The destructive force of an atomic bomb is due to nearly instantaneous and uncontrolled successive fissions of uranium or plutonium atoms in a chain reaction, each fission releasing tremendous energy and also neutrons which produce the succeeding fission (The World Book Dictionary 129). In other words, these bombs are very powerful. This was demonstrated in 1940 ...
- 186: Phosphates in Water Pollution
- Phosphates in Water Pollution Phosphates may be created by substituting some or all of the hydrogen of a phosphoric acid by metals. Depending on the number of hydrogen atoms that are replaced, the resulting compound is described as a primary, secondary or tertiary phosphate. Primary and secondary phosphates contain hydrogen and are acid salts. Secondary and tertiary phosphates, with the exception of those of ...

- 188: Acid Rain
- ... other chemical that is also chiefly responsible for the make-up of acid rain is nitrogen oxide. Oxides of nitrogen is a term used to describe any compound of nitrogen with any amount of oxygen atoms. Nitrogen monoxide and nitrogen dioxide are all oxides of nitrogen. These gases are by-products of firing processes of extreme high temperatures (automobiles, utility plants), and in chemical industries (fertilizer production). Transportation makes up 43 ...
- 189: Cyclohexanone
- ... functional groups. The region of the infrared spectrum which is of greatest interest to organic chemists is the wavelength range 2.5 to 15 micrometers which correspond to approximately 4000 to 600cm-1(Young). When atoms or molecules absorb light, the incoming energy excites a quantized structure to a higher energy level. The type of excitation depends on the wavelength of the light. Electrons are promoted to higher orbirtals by ultraviolet ...
- 190: Acid Rain 10
- ... which has collectedly adopted the mane Nox). There is also a small percentage of hydrochloric acid that makes up hydrochloric acid as well. The equation is as follows: Sulfuric acid when it joins with hydrogen atoms in the air: SO3(g) + H2O(l) = H2SO4(aq) In the air, the nitrogen ion becomes nitric or nitrous acid: NO2(g) + H2O(l) = HNO3(aq) + HNO2(aq) Sulfur dioxide is a colorless, prudent gas ...
