Acid Rain Air Pollution
457 wordsA form of air pollution, currently a subject of controversy because of widespread environmental damage it has been blamed. It forms when oxides of sulfur and nitrogen combine with atmospheric moisture to make sulfuric and nitric acids, which then can be carried long distances from their source before they are released by rain. The pollution may also take the form of snow or fog or be precipitated in dry forms. One large area that has been studied extensively is northern Europe, where acid rain h...

Rate Of Reaction Hydrogen Bonding
2,165 wordsRESEARCH I know that Rennin is an enzyme, so before conducting this experiment I am first going to do some research into enzymes and their effects. 1. Enzymes Enzymes are large globular molecules of which the vast majority are protein in nature, though some, known as 'ribozyme's' are made of RNA. Enzymes have catalytic properties; in other words, they alter the rate of reaction without themselves undergoing a permanent change. Most chemical reactions require an initial input of energy, called ac...

Sulfur Dioxide Acid Rain
318 wordsAcid Rain is, rain that is acidic (naturally). There is a pH level scale which tells if something is acidic or not. Due to certain chemicals in the rain it has a pH level of around 5. 0, and sometimes even 4. 0 (around volcanoes activity). The term acid rain is now used for rain with a pH below 5. Acid rain is caused when gases, generally like sulfur dioxide (SO 2), dissolves into water to form sulfuric acid. The rest comes from different oxides of nitrogen (mainly NO 2 and NO 3). The chemical r...
