Question

Name the elements and numbers of atoms
of each element present in the following compound
1) Baking Soda (NaHCO3)
2) Sodium carbonate ( Na2co3)
3) copper sulphate (Cuso4)
4) Nitric acid (HNO3)
5) Sulphuric acid (H2so4)​

Answer 1

1. Baking soda ...sodium bicarbonate .Formula (NaHco3)

it has one sodium atom,one hydrogen atom,one carbon atom and three oxygen atom.

2. sodium carbonate.commonly known as washing soda. Formula (Na2co3)

it has 2 sodium atoms, 1 carbon atom and 3 oxygen atoms.

3. copper sulphate commonly known as copper (ll) sulphate .Formula (Cuso4)

There are 1(Cu)+1(S)+4(O)+5(2(H)+1(O))=6+5×3=21 atoms per molecule.

4. Nitric acid commonly known as aqua Fortis .Formula (HNCO3)

It has one hydrogen(H) atom ,one nitrogen (N) atom and three oxygen (O) atoms.

5. sulphuric acid commonly known as oil of vitriol.Formula (H2so4)

it has 2 hydrogen atoms,one sulfur atom and four oxygen atoms.
