Some Basic Concepts · Reaction stoichiometry gas volumes

In the reaction,

2 Al(s)+6 HCl(aq)→2 AlX3+(aq)+6 ClX−(aq)+3 HX2(g)\ce{2Al(s) + 6HCl(aq) -> 2Al^{3+}(aq) + 6Cl^{-}(aq) + 3H2(g)}

which of the following statements is correct ?

  1. (1)11.2 L HX2(g)\ce{H2(g)} at STP is produced for every mole of HCl consumed.
  2. (2)67.2 L HX2(g)\ce{H2(g)} at STP is produced for every mole of Al that reacts.
  3. (3)12 L HCl(aq) is consumed for every 6L HX2(g)\ce{H2(g)} produced.
  4. (4)33.6 L HX2(g)\ce{H2(g)} is produced regardless of temperature and pressure for every mole of Al that reacts.
We corrected a printing error in the original paper

The source prints no question after the equation; “which of the following statements is correct ?” added.
