(a)
Interpretation:
Oxidation number of each element is to determine in the reaction.
Concept introduction:
Oxidation number: It is defined as charge the atom would have if electrons are not shared but transfer completely.
Answer to Problem 83A
Explanation of Solution
The given reactions are:
Oxidation number of elements is:
Change in oxidation number in reaction 1:
N in NH4=3
N in NO2 = (-4)
Change in oxidation number in reaction 2:
N in NH4=+5
N in NO2 = (-3)
(b)
Interpretation:
The elements which are oxidized and reduced are to determine in the reaction.
Concept introduction:
Oxidation number: It is defined as charge the atom would have if electrons are not shared but transfer completely.
Answer to Problem 83A
In both reactions nitrogen is oxidized as well as reduced.
Explanation of Solution
The given reactions are:
Oxidation number of elements is:
Change in oxidation number in reaction 1:
N in NH4=3
N in NO2 = (-4)
Change in oxidation number in reaction 2:
N in NH4=+5
N in NO2 = (-3)
Thus in both reactions nitrogen is oxidized as well as reduced.
(c)
Interpretation:
The elements which are oxidizing and reducing agents are to determine in the reaction.
Concept introduction:
Oxidation number: It is defined as charge the atom would have if electrons are not shared but transfer completely.
Answer to Problem 83A
In both reactions nitrogen is oxidizing as well as reducing agent.
Explanation of Solution
The given reactions are:
Oxidation number of elements is:
Change in oxidation number in reaction 1:
N in NH4=3
N in NO2 = (-4)
Change in oxidation number in reaction 2:
N in NH4=+5
N in NO2 = (-3)
Thus in both reactions nitrogen is oxidizing as well as reducing agent.
(d)
Interpretation:
Difference in electron transfer of given reaction is to be determined.
Concept introduction:
Oxidation number: It is defined as charge the atom would have if electrons are not shared but transfer completely.
Answer to Problem 83A
In reaction:
Oxidizing and reducing agents are different but in the following reaction Nitrogen is oxidizing as well as reducing agent.
Explanation of Solution
The given reactions are:
Oxidation number of elements is:
Change in oxidation number in reaction 1:
N in NH4=3
N in NO2 = (-4)
Change in oxidation number in reaction 2:
N in NH4=+5
N in NO2 = (-3)
Thus in both reactions nitrogen is oxidizing as well as reducing agent.
In Reaction:
Zn is reducing agent and Ag is oxidizing agent.

Crude product data is the data collected after the reaction is finished, but before the product is purified. "Pure" product data is the data collected after attempted purification using recrystallization.
