In the reaction , zn + hcl—> zncl2 + h2, 25 grams zn are reacted with 17.5 grams hcl. how many grams of h2 will be produced ? a. 0.382 g of h2 b. 0.479 g of h2 c. 0.7865 g of h2 d. 0.484 g of h2

0.479 g of hydrogen will be produced if 25 grams Zn are reacted with 17.5 grams HCl.

Hydrochloric acid is an aqueous solution of hydrogen gas and chlorine gas.

The reaction is

The number of moles present in Zn will be
