Answer
$Cu(s)+2H_2SO_4(aq)\rightarrow CuSO_4(aq)+SO_2(g)+2H_2O(l)$
Work Step by Step
Copper metal is $Cu(s)$. Sulfuric acid is $H_2SO_4(aq)$. Copper sulfate is $CuSO_4(aq)$. Sulfur dioxide gas is $SO_2(g)$. Water us H_2O(l).
$Cu(s)+H_2SO_4(aq)\rightarrow CuSO_4(aq)+SO_2(g)+H_2O(l)$
Add a coefficient of 2 to $H_2SO_4$ to balance $S$.
$Cu(s)+2H_2SO_4(aq)\rightarrow CuSO_4(aq)+SO_2(g)+H_2O(l)$
Add a coefficient of 2 to $H_2O$ to balance $H$ and $O$.
$Cu(s)+2H_2SO_4(aq)\rightarrow CuSO_4(aq)+SO_2(g)+2H_2O(l)$
