In the reaction, 2Al(s)+6HCl(aq)→2Al3+(aq)+6Cl−(aq)+3H2(g)2\text{Al(s)} + 6\text{HCl(aq)} \rightarrow 2\text{Al}^{3+}\text{(aq)} + 6\text{Cl}^-\text{(aq)} + 3\text{H}_2\text{(g)}

  • A

    11.211.2 L H2_2(g) at STP is produced for every mole of HCl consumed.

  • B

    1212 L HCl(aq) is consumed for every 66 L H2_2(g) produced.

  • C

    33.633.6 L H2_2(g) is produced regardless of temperature and pressure for every mole of Al that reacts.

  • D

    67.267.2 L H2_2(g) at STP is produced for every mole of Al that reacts.
