$M g + {H}_{2} S {O}_{4} \to M g S {O}_{4} + {H}_{2}$

#### Explanation:

Magnesium combined with sulfuric acid produces magnesium sulfate and hydrogen gas.

Reactants:

The symbol for magnesium is $M g$.

The formula for sulfuric acid is ${H}_{2} S {O}_{4}$

Products:

Magnesium forms a $2 +$ ion: $M {g}^{2 +}$

The sulfate ion has a charge of $2 -$: $S {O}_{4}^{2 -}$

The charges balance and thus the formula for
magnesum sulfate is $M g S {O}_{4}$

Hydrogen gas is diatomic: ${H}_{2}$

$M g + {H}_{2} S {O}_{4} \to M g S {O}_{4} + {H}_{2}$

The reaction is balanced as written. Each side has one magnesium atom, two hydrogen atoms and one sulfate ion.
