(b) hydrogen reduces from the substance
(c) oxygen reduces from the substance
(d) none of the above

Answer 1

Answer:

oxygen reduces from the sunstance

Answer 2

Answer:

(b) oxygen reduces from the substance

Explanation:

In the reduction reaction,  hydrogen combines with the substances to reduce it. In a chemical reaction when a substance combines with oxygen, it is oxidation whereas when it combines with the hydrogen, is a reduction.

Also when a substance loses the oxygen it is reduction while if it loses the hydrogen it is oxidation.

In the same way, if an atom loses the electron it is oxidation whereas if it gains the electron it is a reduction reaction.
