(a) + 7 (b) + 5
(c) + 3 (d) – 7​

Answer 1

Answer:

hello

Explanation:

option a) +7.....

Answer 2

The correct option is a.

• The oxidation number of an atom is defined as its oxidation state or by its charge.
• The oxidation state of Oxygen is -2.
• Let the oxidation number of Chlorine be x.
• The molecule is neutral so, the total oxidation number is 0.
• Thus we can write-
• $2x + ( - 14) = 0 \\ 2x = 14 \\ x = 7$
• The value of x is +7.
• The oxidation number of chlorine is +7.
