    2kcl - 2kcl 3o2 is the answer here's how:

    We start with

    1 KClO3 →KCl + O2

    Balance K:

    We have 1 K on the left, so we need 1 K on the right. We put a 1 in front of the KCl.

    1 KClO3 →1KCl + O2

    Balance Cl:

    Cl is already balanced, with 1 Cl on each side.

    Balance O:

    We have 3 O atoms on the left and only 2 on the right. We need 1½ O2 molecules on the right. Uh, oh! Fractions!

    We start over with a 2 as the coefficient.

    2 KClO3 →2KCl + O2

    Now we have 6 O atoms on the left. To get 6 O atoms on the right, we put a 3 in front of the O2.

    2 KClO3 →2KCl+3 O2

    Every formula now has a fixed coefficient. We now should have a balanced equation.
