Write a word equation for 2ZnS (s) + 3O2 (g) - > 2ZnS (s) + 2SO3 (g)

2ZnS (s) + 3O2 (g) - > 2Zns (s) + 2SO3 (g)

the above given equation is unbalanced as it contains 4 moles of sulphur in the output but in the input there are only two aoms of sulphur so to balance the equation we will write the equation as given under

balanced equation is

2ZnS (s) + 3O2 (g) - > 2Zn (s) + 2SO3 (g)

In words:

When 2 moles of solid zinc sulfide reacts with 3 moles of oxygen gas gives 2 moles of solid zinc and 2 moles of sulphur trioxide gas.
