INTRODUCTION: Acid rain is a great problem in our world. It causes fish and plants to die in our waters. As well it causes harm to our own race as well, because we eat these fish, drink this water and eat these plants. It is a problem that we must all face together and try to get rid of. However acid rain on it"s own is not the biggest problem. It cause many other problems such as aluminum poisoning. Acid Rain is deadly. WHAT IS ACID RAIN? Acid rain is all the rain, snow, mist etc that falls from the...
of our lakes, our rivers, our wild life and most importantly us. As well it causes other problems that are very serious as well such as the release of aluminium and lead into our water supplies. We are suffering because of it. In Scotland there are many birth defects being attributed to it. We must cut down the releases of chemicals that cause it. But it will take time, even if we were to stop today we would have the problem for years to come because of the build up in the soil. Let"s hope we can do something.

Niels Bohr"s model of the hydrogen atom, was the primary reason for the understanding of energy levels.Bohr was able to explain the bright line spectrum of hydrogen. Sparked by the recent discovery of the diffraction patterns, scientists believed electrons could be described as waves. Bohr hypothesized that energy is being...

OXYGEN O Oxygen was discovered by a British chemist, Joseph Priestly in 1774, and independantly by Carl Wilhelm Scheele, a Sweedish chemist. Oxygen has many uses - it is used in welding torches, to assist in hospital patient"s breathing and in metal fabrication industries. Oxygen is also used for defense...
