Zinc metаl reаcts with HCl tо fоrm zinc chlоride аnd hydrogen gas. zinc + hydrochloric acid --> zinc chloride + hydrogen gas. If 65.4 g of zinc reacts in this way, it will consume 72.9 grams of HCl and produce 2.0g of hydrogen gas. Based on this information and what you know about the law of conservation, how many grams of zinc chloride will be produced?
