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

Magnesium Chloride + Oxygen produces Magnesium Chlorate.

Magnesium Chloride is an ionic compound. The Magnesium has a charge of ##Mg^(+2)## and Chlorine has a charge of ##Cl^-1##. We need 2 chloride ions to balance one magnesium ion making the formula ##MgCl_2##.

Magnesium Chlorate is an ionic compound. The Magnesium has a charge of ##Mg^(+2)## and Chlorate has a charge of ##ClO_3^-1##. We need 2 chlorate ions to balance one magnesium ion making the formula ##Mg(ClO_3)_2##.

##MgCl_2 + O_2 -> Mg(ClO_3)_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.

##MgCl_2 + 3O_2 -> Mg(ClO_3)_2##
