Answer:
FeSO₄ + 2NaOH → Fe(OH)₂ + Na₂SO₄
Explanation:
The equation for the reaction is:
FeSO₄ + 2NaOH → Fe(OH)₂ + Na₂SO₄
Dissociation of each compound
FeSO₄ → Fe²⁺ + SO₄⁻²
NaOH → Na⁺ + OH⁻
Fe(OH)₂ → Fe²⁺ + 2OH⁻
Na₂SO₄ → 2Na⁺ + SO₄⁻²

The empirical formula for the unknown compound would be: C2H4O (2 molecules of Carbon, 4 molecules of Hydrogen, and 1 molecule of Oxygen)
The balanced chemical formula should be Al2(SO4)3 + 6NaOH = 2Al(OH)3 + 3Na2SO4
Therefore the coefficient of Al(OH)3 is 2!
Hope that helps :)
