Carbonates react with acids to form a salt, water and carbon dioxide gas. When 25.4 g of calcium carbonate are reacted with sufficient hydrochloric acid, how many grams of calcium chloride will be produced?

Answer 1

CaCO3 + 2HCl ==> CaCl2 + H2O + CO2
mols CaCO3 = grams/molar mass
Convert mols CaCO3 to mols CaCl2 using the coefficients in the balanced equation.
g CaCl2 = mols x molar mass.

Answer 2

55g
