MCQ
$\ce{Mg + CuO \rightarrow MgO + Cu}$ Which of the following is wrong relating to the above reaction?
  • A
    $\text{CuO}$ gets reduced.
  • B
    $\text{Mg}$ gets oxidised.
  • ✓
    $\text{CuO}$ gets oxidised.
  • D
    It is a redox reaction.
✓

Answer

Correct option: C.
$\text{CuO}$ gets oxidised.
The reaction $\ce{Mg + CuO \rightarrow MgO + Cu}$ is a redox reaction.
$\text{CuO}$ loses an $O$ atom to form $\text{Cu}.$ Thus, it is reduced.
$\text{Mg}$ gains an $O$ atom. Thus, it is oxidized.
