4. Zn (s) + 2 HCl(aq) → ZnCl₂ (aq) + H₂(g) (This is just stoichiometry.) Reaction Type: Single Displacement Grams of Product (List the Product and the Amount): 7.48 x 10 g ZnCl₂ and 1.11 x 10¹ g H₂ ? g ZnCl₂ = 3.59 x 10² g Zn x 1 mol Zn x 65.37 g Zn 1 mol ZnCl₂ x 1 mol Zn 136.27 g ZnCl₂ = 7.48 x 10 g ZnCl₂ 1 mol ZnCh ? g H₂ = 3.59 x 10 g Zn x 1 mol Zn x 2.02 g H₂ = 1.11 x 10¹ g H₂ 1 mol H₂ 65.37 g Zn YOU MUST CALCULATE THE AMOUNT OF EXCESS REACTANT LEFT OVER AT THE END OF THE REACTION!!!!!!! 1 mol H₂ x 1 mol Zn What is the amount of excess reactant left over at the end of this reaction? 3.59 x 10^2 g strip of zinc is dropped into a test tube of containing excess hydrochloric acid
