Answer
$Zn(s)+H_2SO_4(aq)\rightarrow H_2(g)+ZnSO_4(aq)$
Work Step by Step
Solid zinc metal exists as an element, $Zn$. Sulfuric acid is $H_2SO_4$. Hydrogen gas exists as $H_2$. Zinc sulfate is $ZnSO_4$.
$Zn(s)+H_2SO_4(aq)\rightarrow H_2(g)+ZnSO_4(aq)$
The equation is balanced as written with one molecule of each element or compound.
