essay – Acid Rain Acid rain has been an important global issue for centuries. Although most acid rain is caused by human activities‚ some acid rain occurs naturally. An example of natural acid rain is erupting volcanos‚ they give off smoke containing water vapor‚ carbon dioxide‚ sulphur dioxide and nitrogen compounds. The sulphur dioxide and nitrogen compounds cause small amounts of acid rain near the volcano. Pure water is not an acid‚ but even clean rainwater is slightly acidic. This is because

The milgram experiment. The three people involved were: the one running the experiment‚ the subject of the experiment a volunteer‚ and a person pretending to be a volunteer. These three persons fill three distinct roles: the Experimenter an authoritative role‚ the Teacher a role intended to obey the orders of the Experimenter‚ and the Learner the recipient of stimulus from the Teacher. The subject and the actor both drew slips of paper to determine their roles‚ but unknown to the subject‚ both slips

Acid Rain Within this past century‚ acidity of the air and acid rain have become recognized as one of the leading threats to our planet’s environment. No longer limited by geographic boundaries‚ acid causing emissions are causing problems all over the world. Some laws have been passed which limit the amount of pollutants that are released into the air‚ but tougher legislation must be implemented before this problem can be overcome. Acid rain is produced‚ when automobiles‚ smelters‚ power

Acids‚ Bases‚ and pH Lab In this lab the testing of whether or not a substance was an acid or a base occurred. Each substance was tested with the indicators red litmus paper‚ blue litmus paper‚ pH paper‚ phenolthalein‚ bromthymol blue‚ and phenol red. While the substances were tested the group noticed that the substances tested with the red and blue litmus paper‚ the phenolthatein‚ bronthmol blue were the easiest to interpret. The color changes that occurred when this indicator was put into a substance

and these comprise only 20 kinds of amino acids in various combinations. These 20 kinds of amino acids are essential to the body. In addition to being the materials for proteins‚ they are used as an energy source for the body as necessary. Further‚ each amino acid plays an important and unique role in the body. The list below shows the role of each amino acid. | Valine Leucine Isoleucine | All of these 3 amino acids are called branched chain amino acid(BCAAs). They perform the important functions
