In the reaction :
`2Al (s) + 6HCl(aq) to 2Al^(3+) (aq) + 6Cl^(-) (aq) + 3H_2O(g)`

Options

A. 33.6L `H_2` (g) is produced regardless of temperature and pressure for every mole Al that reacts.
B. 67.2 L `H_2` (g) at STP is produced for every mole Al that reacts.
C. 11.2 L `H_2` (g) at STP is produced for every mole HCl (aq) consumed.
D. 6L HCl (aq) is consumed for every `3L H_2` (g) is produced.

Answer

C

Explanation

For each mole of Al reacted 1.5 mole of `H_2` (g) (or 33.6 L at STP )is formed and for each mole of HCl consumed 0.5 mole of `H_2` (g) (or 11.2 L at STP) is formed
