Question

Balance the following chemical equation :-
ZnS + O₂ ---> ZnO + SO₂

Answer 1

the required balanced equation

2ZnS + 3O2 ------> 2ZnO + 2SO2

Answer 2

Hi deepika,
Given equation,
ZnS + O₂ ---> ZnO + SO₂
Compare the no.of atoms of each element on both sides,
Element-no.of atoms in reactants - no,of atoms in products
Zn-1-1
S-1-1
O-2-3
The balanced equation is
2ZnS + 3O₂ --->2ZnO + 2SO₂
Now again compare the no.of atoms of each element on both sides
Zn-2-2
S-2-2
O-6-6
So,balanced. Hope it helps
