MCQ
Identify the product $(s)$ which will be formed by using the information provided about the reactants:
$\ce{Mg(s) + 2HCl} \rightarrow$
  • A
    $\mathrm{MgCl}_2+\mathrm{H}$
  • B
    $\mathrm{MgH}_2+\mathrm{Cl}_2$
  • C
    $\mathrm{MgCl}_3+\mathrm{H}_2$
  • ✓
    $\mathrm{MgCl}_2+\mathrm{H}_2$
✓

Answer

Correct option: D.
$\mathrm{MgCl}_2+\mathrm{H}_2$
$\mathrm{Mg}+2 \mathrm{HCl} \rightarrow \mathrm{MgCl}_2+\mathrm{H}_2$
