Calcium carbonate is decomposed by HCl as follows: CaCO3 + 2HCl→CaCl2 + H2O+CO2

a. Calculate the mass of water produced by the reaction of 4 mol. Of CaCO3
with 4 mol. Of HCl.

b. Define limiting reagent.

c. If 2 mol. Of CaCO3
produces 40 L of CO2 at NTP upon reaction with excess
HCl, what is the % age yield of the reaction.

d. If 250 g. of CaCO3 upon reaction with excess HCl gives 222 g. of CaCl2,
what is the % age purity of CaCo3?
