4. 5 molecules of SO2
5. 4 atoms of chlorine
6. 5 molecules of chlorine
7. 1 molecule of CuS
8. 10 molecules of H2S

Question 2:

The number written infront of each element is the number of atoms of that element in the molecule of each compound$.$

1. H = 2, S = 1, O = 4
2. Ca = 1, Cl = 2
3. Fe = 2, O = 3
4. Na = 1, Cl = 1
5. H = 4, O = 4 (2 × 2)
6. C = 8, H = 24
7. K = 4, S = 2, O = 6
8. K = 3, N = 3, O = 9
9. N = 1, H = 4, Br = 1
10. H = 4, O = 2
11. H = 9, P = 3, O = 12
12. Si = 2, O = 4
13. Pb = 1, N = 2, O = 6
