Which is the oxidizing agent in the following reaction?
CuO(s) + H₂(g) → Cu(s) + H₂O(ℓ)

CuO is reduced by losing oxygen atoms. Thus, CuO is a reducing agent as it undergoes reduction.

The reaction, 3MnO₂(s) + 4Al(s) → 3Mn(ℓ) + 2Al₂O₅(s) + Heat is

an example of:

Which is the reducing agent in the following reaction?
