Question

Calcium Carbonate reacts with HCl to produce Calcium chloride, carbon dioxide and water.(I) calculate the number of moles of CO2 produced from 36.5g of HCl (ii) Calculate the amount of Calcium chloride produced (in g) when 3 moles of calcium Carbonate reacts with HCl

Answer 1

i. 0.50 mol CO2

ii. 332.94g CaCl2

Step-by-step explanation:

CaCO3 + 2HCl -> CaCl2 + CO2 + H2O

i. 36.5g HCl * 1 mol HCl/36.46g HCl * 1 mol CO2/2 mol HCl = 0.50 mol CO2

ii. 3 mol CaCO3 * 1 mol CaCl2/1 mol CaCO3 * 110.98g CaCl2/1 mol CaCl2 = 332.94g CaCl2
