Answer:
Unbalanced
Step-by-step 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.
