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

Options

A. 33.6 L `H_(2)` (g) is produced regardless fo temperature and pressure for every mole of Al that reacts.
B. 67.2 L `H_(2)`(g) at STP is produced for every mole of Al that reacts.
C. 11.2 L `H_(2)` (g) at STP is produced for every mole of HCl (aq) consumed.
D. 6 L HCl (aq) is consumed for every 3 L of `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.
