Question:
Chalkboard chalk is made from calcium carbonate and calcium sulfate, with minor impurities such as SiO2 . Only the CaCO3 reacts with dilute HCl(aq). What is the mass percent CaCO3 in a piece of chalk if a 3.28 g sample yields 0.981 g CO2(g)?
CaCO3(s) + 2 HCl(aq) → CaCl2(aq) + H2O(l) + CO2(g)
