concentration on rate of reaction Plan: We are investigating the effect of nitric acid on calcium carbonate. We are doing this experiment‚ as we would like to understand the effect that acid rain has on limestone. We also want to understand how acid can have an effect on rate of reaction. The word equation for the reaction that will take place is: Calcium Carbonate + Nitric Acid Calcium Nitrate + Carbon Dioxide + Water The balanced symbol equation is: CaCO3 + 2HNO3

How Acid Rain Affects Organisms in Aquatic Biomes Through the advancement of technology‚ the issue of the air surrounding the earth might have been one of the most often matters to be brought up and discussed among scientists and engineers. Acid rain is one of the more serious environmental problems and it is closely related to the air pollution. Nowadays‚ it has affected large part of US‚ Europe and Canada. People start to be concerned about acid rain since it is getting worse in the passed
