what mass of hydrochloric acid reacts when 87.7 grams of aluminum dissolves in excess hydrochloric acid?
2Al + 6HCl = 2AlCl3 + 3H2 n = m/M M (Al) = 26.9 g/mol M (HCl) = 36.5 g/mol n (Al) = 87.7/26.9 = 3.3 mol n (HCl) =...

When aluminum reacts with hydrochloric acid, HCl, both aluminum chloride and hydrogen gas are produced. If 108 grams of aluminum is reacted, what volume of gas may be collected at STP?
Solution:Balanced chemical equation:2Al + 6HCl → 2AlCl3 + 3H2According to the equation above: n(Al)/2 = n(H2)/3The molar mass of Al is 27 g/mol.Hence,Moles of Al = (108 g Al) ×...
