Write the ratio of the elements in the following compounds a) CaCl2 ……………………………………………
b) NO2 ……………………………………………
c) NaNO3 ……………………………………………
d) H2SO4 ……………………………………………

a) CaCl2 = 1:2

b) NO2 = 1:2

c) NaNO3 = 1:1:3

d) H2SO4 = 2:1:4

Explanation:

The ratio of the elements in each of the given compound can be calculated as follows:

The number of atoms of each element in each compound will serve as the basis of the ratio.

1. In CaCl2, 1 Ca atom combines with 2 Cl atoms, hence, the ratio will be 1:2

2. NO2 = 1:2 because 1 atom of N combine with 2 atoms of O

3. NaNO3 = 1:1:3 because 1 atom of Na, 1 atom of N and 3 atoms of O are involved.

4. H2SO4 = 2:1:4 because 2 atoms of H, 1 atom of S and 4 atoms of O are involved.
