Is mg(c1o3)2 to mgc12+o2 balanced or unbalanced?

Unbalanced

Explanation:

For an equation to be balanced, there needs to be equal number of atoms of each elements in the reactant side and the product side.

In the chemical reaction:

Mg(ClO₃)₂ → MgCl₂ + O₂

Look at the number of atoms in the reactant side and compare them to the number of atoms in the product side

Reactant              Product

Mg = 1                   Mg = 1

Cl = 2                    Cl = 2

O = 6                     O = 2

The number of oxygen atoms on the reactant side is not equal to the number of oxygen atoms on the product side. This means that they are not equal.
