Question:

Balance the following reaction: $\ce{CuS + SO4^{2-} -> CuO + SO2}$

My Efforts: Number mentioned in the brackets oxidation number of S

I have found out that the oxidation half-reactions and reduction half-reactions are as follows:

$\ce{CuS^{(-2)}-> ^{(4)}SO2}$ Oxidation half reaction

$\ce{^{(6)}SO4^{2-} -> ^{(4)}SO2}$ Reduction half reaction

Problem:

In this what about $\ce{CuO}$ which in the product side. I have also learned that we need to balance the spectator ion before charges if the spectator ion is other than oxygen and hydrogen.

Here there is no $\ce{Cu}$ in reduction half reaction. So, I think there is something is wrong in my reduction half-reaction.

Balance the following reaction: $$\ce{CuS + SO4^{2-} -> CuO + SO2}$$

Below, the number mentioned in the parenthesis is the oxidation number of sulfur.
I have found out that the oxidation half-reactions and reduction half-reactions are as follows:

\begin{align} \ce{CuS^{(-2)} &-> ^{(4)}SO2}&& \text{Oxidation half reaction}\\ \ce{^{(6)}SO4^{2-} &-> ^{(4)}SO2}&& \text{Reduction half reaction} \end{align}

Problem:

In this, what about $\ce{CuO}$ in the product side? I have also learned that we need to balance the spectator ions before charges if the spectator ion is other than oxygen and hydrogen.
