Answer:
A chemical bond is defined as the force which helps to bind more than two atoms in a molecule. There are different types of chemical bonding are present in molecules such as:
1) Ionic bonding: Because of the transfer of electrons it is present in ionic compounds. BaS is an example of ionic bonding which is containing some covalent character.
2) Covenant bonding: Because of the sharing of electrons it forms molecules. Rubber is the example of covalent bonding with some van der walls.
3) Metallic bonding: In the free state it is present in atoms of metal such as Brass is a good example of a metallic bonding because it is a metal alloy.
4) Van der walls bonding: In atoms, It includes repulsion and attraction. Solid xenon is the example of Van der wall bonding because it is an inert gas.
D = m / V
2.7 = 8.1 / V
V = 8.1 / 2.7
V = 3.0 mL
Answer:
The total number of atoms is 12 + 22 + 11 = 45, so carbon atoms are 12/45 of the total.
