Clean Air Act H 2 O
1,801 wordsAcid rain is exactly what it suggests- rain that is acidic. The definition of 'acid rain' is rain with a pH of below 5. 6. Rain becomes acidic because of gases that dissolve in the rain. Approximately 70 % of acid rain is a result of dissolved sulfur dioxide (SO 2) which forms Sulfuric Acid. The remaining 30 % or so comes from various Nitrogen Oxides (mostly NO 2 and NO 3 which has collectedly adopted the mane Nox). There is also a small percentage of hydrochloric acid that makes up hydrochloric...

Evaporating Dish Aluminum Foil
2,222 wordsPurpose: To conduct experiments and to determine whether they are physical or chemical changes Pre-Lab Notes: Before we conduct these experiments there are some topics that we must discuss. As I stated in the purpose, in this lab we are going to be looking at some experiments, and we have to determine whether they are a cause of chemical or physical changes. The purpose for all the labs that we will be doing will be the same. During a chemical change a new substance is formed, it is irreversible...

Petri Dishes Flowering Plants
3,855 wordsIs there an effect on Rhizobium bacteria by changing its pH? Steve Lincoln Period 3 12 / 7 / 98 Question What are the effects of varying pH levels on Rhizobium bacteria, and can a pH resistant Rhizobium culture be grown? Hypothesis Alterations of the balanced habitat such as the change of pH levels can drastically alter the life of bacteria and can directly affect chemical reactions of enzymes released by the bacteria. Using this information the change in pH will have an effect on the Rhizobium ...
