Step 1

Dear student, we answer three parts in a question. I am answering the first three parts. If you need answer for other parts, kindly re-post.

Oxidant is the species in a redox reaction which gets reduced itself and oxidises other species. Thus, the oxidation number of oxidant is reduced and it gains electrons in a redox reaction.

A reductant is a species in a redox reaction which gets oxidised itself and reduces other species. Thus, the oxidation number of the reducatnt is increased and it lose electrons in the redox reaction.

Step 2

1) In this part,

Oxidant : NO3- because oxidation number of nitrogen has reduced in the given reaction.

Oxidation number of N in NO3- : x + 3 (-2) = -1

x = +5

Oxidation Number of N in NO : x -2 = 0

x = +2

Thus, the change in oxidation number is 3 and the number of electrons gained per formula is 3.

Reductant : Cu

Oxidation number of Cu has increased from 0 to +2

Thus, electrons lost per formula is 2.

Step 3

2 ) In this part,

Oxidant : Cl2

The oxidation number of Cl is reduced from 0 (in Cl2) to -1 ( in Cl-)

There are two chlorine atoms in the reactant species while one chlorine atom in the product species. Thus, balancing the number of atoms:

Cl2 ( total oxidation number = 0) is changed to 2 Cl- (total oxidation n...
