Answer:
False
Explanation:
It is not correct to assert that a chemical change has occurred if the number of atoms is greater after the reaction than it was before the reaction.
For every chemical reaction, the law of conservation of mass must be strictly adhered.
The law states that "during a chemical reaction, matter is neither created nor destroyed, atoms are simply rearranged".
By the virtue of this law, the number of atoms at the beginning and the end of the reaction must remain the same for this law to be applicable.

Answer:
Br - C ≡ N
Explanation:
To draw the Lewis line-bond structure we need to bear in mind the octet rule, which states that in order to gain stability each <em>atom tends to share electrons until it has 8 electrons in its valence shell</em>.
- C has 4 e⁻ in its valence shell so it will form 4 covalent bonds.
- Br has 7 e⁻ in its valence shell so it will form 1 covalent bond.
- N has 5 e⁻ in its valence shell so it will form 3 covalent bonds.
The most stable structure that respects these premises is:
Br - C ≡ N
It does not have any H atom.
