Question

Calculate the percent yield of H2 of a reaction that produces 0.50 moles of H2 from 45 grams of HCl and excess Al (aluminum) in the reaction below (which is not balanced):

Al + HCI = AlCl2 + H2

Answer 1

Balanced equation:

2 moles of Al react with 6 moles of HCl. 2 moles of AlCl₃ and 3 moles of H₂ are produced.

The answer is C.
