1. S - Sulphur O - Oxygen
2. Reactant side is the left side , so 1
Product side on right , still 1
3. Reactant side oxygen: 6
Product side oxygen: 3
4. The equation is not balanced as there are is a different amount of oxygen atoms on each side. On the reactant side , there are 6 oxygen atoms however on the product side , there are 3 oxygen atoms. The oxygen is the only element which makes the equation unbalanced as the amount of sulphur atoms is equal on each side.
