| **Determine the volume of carbon dioxide that will be released during the interaction of 120 g of chalk with hydrochloric acid, if the practical reaction yield is 70%?**

CaCO3 + 2HCL = CaCl2 + H2O + CO2

n (caco3) = m / M = 120/100 = 1.2 mol

The level of the reaction shows that n caco3: n co2 as 1: 1, which means n co2 = 1.2 mol

V (CO2) = n * Vm; V (CO2) = 1.2 * 22.4 = 26.88L (this is theoretical V)

Looking for a practical V

V = 22.88L * 0.7 = 18.816L

Answer: V (CO2) = 18.816L
