In the reaction,$2Al_{(s)} + 6HCl_{(aq)} \rightarrow 2Al^{3+}_{(aq)} + 6Cl^{-}_{(aq)} + 3H_{2(g)}$

• A
  $11.2 \ L$ of $H_{2(g)}$ at $STP$ is produced for every $2 \ moles$ of $HCl_{(aq)}$ consumed
• B
  $6 \ L$ of $HCl_{(aq)}$ is consumed for every $3 \ L$ of $H_{2(g)}$ produced
• C
  $33.6 \ L$ of $H_{2(g)}$ is produced at $STP$ for every mole of $Al$ that reacts
• D
  $11.2 \ L$ of $H_{2(g)}$ at $STP$ is produced for every mole of $HCl_{(aq)}$ consumed
