1. Marble is calcium carbonate (CaCO3). Its reaction with hydrochloric acid is CaCO3 + 2HCl CaCl2 + CO2 + H2O What was the gas produced when marble reacted with HCl? Write chemical equations for the reactions of marble with two other acids. Do these reactions have anything in common? In light of your observations, speculate on the damage to marble statues and buildings caused by acid rain. 2. What generalization can you make about the effect of changing...
Calcium carbonate is used in many antacids to neutralize stomach acid, as depicted by the following chemical equation: CaCO3(s) + 2 HCl(aq) → CaCl2 + H2O(l) + CO2(g) If 250. mg of calcium carbonate reacts with 5.64 g of hydrochloric acid, how much hydrochloric acid will remain? Provide your answer in g.
Write molecular, ionic, and net ionic equation for the reaction of HCl and KOH. Compare this to other net ionic reactions to other strong acids and bases. What volume of 0.800 mol/L KOH is needed to completely neutralize 15.0 mL of 0.500M H2SO4? In the following reaction, 6.088 g of calcium carbonate reacted with 60.00 mL of 1.3 mol/L HCl. What mass of CaCO3 remains unreacted? CaCO3 + 2HCl → CaCl2 + CO2 + H2O
