Chlorine can be generated by heating together calcium hypochlorite and hydrochloric acid. Calcium chloride and water are also formed.
a) If 60.0 g of Ca(OCl)2 and 325 mL of 6.00 M HCl are allowed to react, how many grams of chlorine gas are formed?
b) 12.6 g chlorine gas is isolated in the laboratory. Calculate the % yield.
