Describe the Barium chlorate (Ba(ClO3)2) breaks down to form barium chloride and oxygen. What is the balanced equation for this reaction? When counting atoms in parentheses, multiply all subscripts by the number outside the parentheses to get the number of atoms.
You have to balance the equation to get the same number of oxygens as on the other side with the reactants. So adding a 3 before O2 gives you six oxygens on each side.
