Question

Write two oxidation reaction in which hydrogen is reduced .​

Answer 1

Answer:

CuO+H2 react with heat will give you Cu + H2O

Answer 2

Answer:

H₂SO₄+Zn=ZnSo₄(colourless)+H₂(gas)

H₂SO₄+Fe=FeSO₄(green)+H₂(gas)

Explanation:

Both Zn and Fe are more reactive than H, thus they displace H from the SO4 solution.
