In the reaction 2Al(s) + 6HCl(aq) $\to$ 2Al3+ (aq) + 6Cl-(aq) + 3H2(g)

Question

In the reaction

2Al(s) + 6HCl(aq) $\to$ 2Al³⁺ (aq) + 6Cl^-(aq) + 3H₂(g)

11.2 L H₂(g) at STP is produced for every mole HCl(aq) consumed

6 L HCl(aq) is consumed for every 3L H₂(g) produced

33.6 L H₂(g) is produced regardless of temperature and pressure for every mole that reacts

67.2 H₂(g) at STP is produced for every mole Al that reacts
