Q. Consider the following reaction
$Z n + 2 H Cl \to Z n C l_{2} + H_{2}$
If $0.3$ mol of $Z n$ reacts with $0.52$ mol of $H Cl$ , then which is incorrect regarding above reaction?

$0.26$ mol of $Z n C l_{2}$ is formed

$5.82 L$ of $H_{2}$ at $STP$ is produced

$H Cl$ is limiting reagent

$0.1$ mol of $Z n$ is left

$g i v e n Z n 1 m o l e 0.3 + 2 H Cl \to Z n C l_{2} + H_{2} 2 m o l e 0.52$
$0.3$ mole of $Z n$ require $0.6$ mole of $H Cl$ $∴$ $H Cl$ is the limiting reagent

Q. Consider the following reaction Zn+2HCl→ZnCl2​+H2​ If 0.3 mol of Zn reacts with 0.52 mol of HCl, then which is incorrect regarding above reaction?

0.26 mol of ZnCl2​ is formed
