In heavily polluted climates excess sulfur dioxide in the atmosphere is converted into sulfuric acid via several reactions, sulfuric acid created in this manner is often referred to as acid rain. Acid rain poses a risk to historical structures many of which are made of limestone or calcium carbonate. Acid rain reacts with limestone to make calcium sulfate, water, and carbon dioxide. Over time the reaction between acid rain and limestone degrades many historical structures, as shown below. Acid Rain Damage to a Statue of George Washington Write the complete balanced equation for the reaction of acid rain and limestone.”

Determine the limiting and excess reagent if 7.50 g of \(\ce{H_{2}S}\) is allowed to react with 12.75 g of \(\ce{SO_{2}}\) via the following reaction, $$\ce{2H2S + SO2 → 3S + 2H2O}$$

In the atmosphere excess sulfur dioxide will react with water to form sulfurous acid a precursor to acid rain, via the following reaction. $$\ce{SO_{2}(g) + H_{2}O(l) -> H2SO3(l)}$$ How many grams of of sulfur dioxide is needed to create 29.36 g of sulfurous acid?
