The incorrect statement regarding above reactions is
$\mathop {Al}\limits_{Metal} \xrightarrow{{HCl(aq.)}}'X' + Gas\,'P'$
$\mathop {Al}\limits_{metal} \xrightarrow[{ + {H_2}O}]{{NaOH\,(aq.)}}'Y' + Gas\,'Q'$
$Al$ shows amphoteric character
Gas $'P'$ and $'Q'$ are different
Both $X$ and $Y$ are water soluble
Gas $Q$ is inflammable
