B. +1

C. -5

D. -1

Answer 1

The oxidation number of chlorine in KClO3 is +5 (option A).

How to calculate oxidation number?

The oxidation number of an element is the hypothetical charge of an atom within a molecule.

The oxidation number of an element like chlorine in a compound like Pottasium chlorate can be calculated as follows:

The oxidation number of the elements in KClO3 is as follows:

• K = +1
• Cl = x
• O = -2

1 + x - 2(3) = 0

x - 5 = 0

x = +5

Therefore, the oxidation number of chlorine in KClO3 is +5.
