Calcium chloride is formed of 84.4 g of limestone (contains a large percentage of CaCO 3 _3 3 ) and excess of HCl, that means CaCO 3 _3 3 from limestone is limiting reactant. We have to calculate the percentage of CaCO 3 _3 3 in limestone if 81.8 g of CaCl 2 _2 2 is formed. CaCO 3 _3 3 + 2HCl → rightarrow → CaCl 2 _2 2 + H 2 _2 2 O + CO 2 _2 2
