Figure A represents a non polar covalent bond while figure B represents a polar covalent bond.
<h3>What is a chemical bond?</h3>
A chemical bond is formed when two atoms are linked. The bond may be ionic, covalent, polar covalent or metallic in nature.
We shall now consider the properties of figures A and B.
For figure A:
- Equal sharing of electrons
- Cl - Cl bond
- Non - polar covalent
For figure B
- Unequal sharing of electrons
- N - H bond
- Polar covalent

The mass percentage of hydrogen in 300 g of sucrose is 9.75%
From the question given above, we were told that:
2 g of sucrose contains 6.50% (ie 0.065) hydrogen
Thus, we can obtain the percentage of hydrogen in 300 g of sucrose as follow:
2 g of sucrose contains 0.065 hydrogen.
Therefore,
300 g of sucrose will contain = = 9.75% of Hydrogen.
Thus, 300 g of sucrose contain 9.75% of Hydrogen.
