Dihydrogen reacts with CuO to give

Dihydrogen reacts with

CuO

to give

Options

ACu{ $\left(OH\right)}_{2}$
B $Cu\left(s\right)$
C ${Cu}_{2}O$
D ${CuH}_{2}$

Correct answer

B. $Cu\left(s\right)$

Step-by-step solution

$CuO\overset{{H}_{2}}{\to}Cu + {H}_{2}O$

Copper oxide undergoes reduction to form elemental copper and water. This is a redox reaction. Since oxygen is removed from the $CuO$ it is undergoing reduction. And hydrogen is getting oxidised.
