We know that the oxygen (O2) causes a glowing splint to reignite, however, let us check what is missing on the products side of the chemical equation: <span>
KBrO3 → KBr + ?
As we see, oxygen (O2) is the element missing from the other side. Therefore the balanced chemical equation for this decomposition is as follows: </span>
<span>2KBrO3 → 2KBr + 3O2 </span>
