Hailie Macias · Answer 1

The oxidation number of elements in equation below are,

4NH₃ + 3Ca (ClO) ₂ → 2N₂ + 6H₂O + 3CaCl₂

O. N of N in NH₃ = - 3

O. N of Ca in Ca (ClO) ₂ and CaCl₂ = + 2

O. N of N in N₂ = 0

O. N of Cl in Ca (ClO) ₂ = + 1

O. N of Cl in CaCl₂ = - 1

Oxidation:

Oxidation number of Nitrogen is increasing from - 3 (NH₃) to 0 (N₂).

Reduction:

Oxidation number of Cl is decreasing from + 1 [Ca (ClO) ₂] to - 1 (CaCl₂).

Result:

N is oxidized and Cl is reduced.
