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...
CaCO3(s) = Cao (s)+CO2 (g) When heated strongly, solid calcium carbonate decomposes to produce solid calcium oxide and carbon dioxide gas, as represented by the equation above. A 2.0 mol sample of CaCO3(s) is placed in a rigid 100. L reaction vessel from which all the air has been evacuated. The vessel is heated to 898°C at which time the pressure of CO2(g) in the vessel is constant at 1.00 atm, while some CaCO3(s) remains in the vessel. a. Calculate...
