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.
