The equation which balances the given chemical reaction between magnesium and oxygen is 2Mg + O₂ → 2MgO.
Balanced equations are those equations in which each entities present in reactant side as well as on product side is equal.
Given chemical reaction:
Mg + O₂ → MgO
Above reaction is not balanced as number of oxygens are not equal on both sides.
This is not a balanced equation as number of magnesium atom is not equal.
This is also not a balanced equation as oxygen atoms are not equal on both sides.
This is a balanced equation as number of each atoms are equal on both sides.
This is not a balanced equation as number of magnesium atom is not equal.
Hence balanced equation is 2Mg + O₂ → 2MgO.
