In the reaction,
2Al(s) + 6HCl(aq) → 2Al3+(aq) + 6Cl–(aq) + 3H2(g)
(a)11.2L H2(g) at STP is produced for every mole HCl(aq) consumed
(b) 6L HCl(aq) is consumed for every 3L H2(g) produced
(c) 33.6L H2(g) is produced regardless of temperature and pressure for every mole Al that reacts
(d) 67.2L H2(g) at STP is produced for every mole Al that reacts
