Answer:
C
Explanation:
Ba(ClO3)2 → BaCl2 + 3O2
According to this question, Barium chlorate (Ba(ClO3)2) breaks down to form barium chloride (BaCl2) and oxygen (O2). The equation is as follows:
Ba(ClO3)2 → BaCl2 + O2
One would notice that this equation is not BALANCED because the number of atoms of each elements are not the same on each side of the equation.
- There is one atom of Barium (Ba) on both reactants and product side
- There are two atoms of chlorine (Cl) on both reactants and product side
- There is an unven number of atoms of oxygen on both sides. That is, 6 atoms of oxygen on reactant side but 2 atoms on product side.
To balance the number of oxygen atom, we add coefficient 3 to the oxygen atom on the product side to have 6-6 for both sides. That is;

What happens when electrons in atoms absorb or release energy? When electrons absorb or release energy, their electrons can move to higher or lower energy levels. These electrons lose energy by emitting light when they return to lower energy levels.
