In the reaction, 2 Al ( s )+6 HCl ( aq ) → 2 Al^3+( aq )+6 Cl^-( aq )+3 H_2( g )
In the reaction,
$$2 \mathrm{Al}(\mathrm{~s})+6 \mathrm{HCl}(\mathrm{aq}) \rightarrow 2 \mathrm{Al}^{3+}(\mathrm{aq})+6 \mathrm{Cl}^{-}(\mathrm{aq})+3 \mathrm{H}_2(\mathrm{~g})
$$
Official answer
From NTA’s final answer key for this paper.
(2)
$\displaystyle 11.2 \mathrm{~L} \mathrm{H}_2(\mathrm{~g})$ at STP is produced for every mole of HCl consumed.
