Balanced equation:
Cu + H2SO4 -> CuSO4 + SO2 + 2H2O

Explanation:
Copper (Cu) reacts with sulfuric acid (H2SO4) to form copper(II) sulfate (CuSO4), sulfur dioxide (SO2), and water (H2O).

In this reaction, copper displaces hydrogen in sulfuric acid to form copper sulfate. Sulfur dioxide and water are the byproducts of this reaction.

The oxidation states of the elements in this reaction are as follows:
Cu: 0 -> +2
H: +1 -> +1
S: +6 -> +4
O: -2 -> -2

This reaction is an example of a single displacement reaction, where one element replaces another in a compound.
