Balance the equation above. If you perform this reaction with 30.0 mL of 4.50 M HCl and 20.5 grams of zinc, what volume of H2, measured at 740 mm Hg and collected over water 27.0oC, can be obtained?  (The vapor pressure of water at 27oC = 26.7 mm Hg) Zn = 65.38 g/mol HCl = 36.5 g/mol H2 = 2.0 g/mol
