Concept explainers
(a)
Interpretation:
To write the formula of a compound of elements N that cannot act as an oxidizing agent.
Concept introduction:
If an element is in minimum oxidation state than it will not act as oxidizing agent that is it would not undergo further reduction.
(b)
Interpretation:
To write the formula of a compound of elements S that cannot act as an oxidizing agent.
Concept introduction:
If an element is in minimum oxidation state than it will not act as oxidizing agent that is it would not undergo further reduction.
(c)
Interpretation:
To write the formula of a compound of elements Cl that cannot act as an oxidizing agent.
Concept introduction:
If an element is in minimum oxidation state than it will not act as oxidizing agent that is it would not undergo further reduction.
