Answer:
a) CaCl2 = 1:2
b) NO2 = 1:2
c) NaNO3 = 1:1:3
d) H2SO4 = 2:1:4
Step-by-step 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.
