# What is the chemical equation for magnesium chloride + oxygen ---> magnesium chlorate?

May 13, 2014

Magnesium Chloride + Oxygen produces Magnesium Chlorate.

Magnesium Chloride is an ionic compound. The Magnesium has a charge of $M {g}^{+ 2}$ and Chlorine has a charge of $C {l}^{-} 1$. We need 2 chloride ions to balance one magnesium ion making the formula $M g C {l}_{2}$.

Magnesium Chlorate is an ionic compound. The Magnesium has a charge of $M {g}^{+ 2}$ and Chlorate has a charge of $C l {O}_{3}^{-} 1$. We need 2 chlorate ions to balance one magnesium ion making the formula $M g {\left(C l {O}_{3}\right)}_{2}$.

$M g C {l}_{2} + {O}_{2} \to M g {\left(C l {O}_{3}\right)}_{2}$

Keep in mind that oxygen is diatomic and therefore must be ${O}_{2}$.

To balance the equation we place a coefficient of 3 in front of the oxygen.

$M g C {l}_{2} + 3 {O}_{2} \to M g {\left(C l {O}_{3}\right)}_{2}$
