Answer:

#Mg + H_2SO_4->MgSO_4 +H_2#

Explanation:

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

Reactants:

The symbol for magnesium is #Mg#.

The formula for sulfuric acid is #H_2SO_4#

Products:

Magnesium forms a #2+# ion: #Mg^(2+)#

The sulfate ion has a charge of #2-#: #SO_4^(2-)#

The charges balance and thus the formula for
magnesum sulfate is #MgSO_4#

Hydrogen gas is diatomic: #H_2#

#Mg + H_2SO_4->MgSO_4 +H_2#

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