2ag + h2s ? ag2s + h2 which statement is true about this chemical equation? a) ag (silver) is oxidized and h (hydrogen) is reduced. b) ag (silver) is reduced and h (hydrogen) is oxidized. c) s (sulfur) is reduced and h (hydrogen) is oxidized. d) s (sulfur) is oxidized and ag (silver) is reduced.

The correct answer is Option A.

Explanation:

Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

For the given chemical reaction:

The half cell reactions for the above reaction follows:

Oxidation half reaction:  

Reduction half reaction:  

As, silver is loosing 1 electron to form silver cation. Thus, it is getting oxidized. Hydrogen is gaining 2 electrons to form hydrogen atom. Thus, it is getting reduced.

Hence, the correct answer is Option A.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
