Question

Tarnish is produced by a redox reaction that occurs when a metal reacts with a nonmetallic compound. the black tarnish on a silver dish might be produced by a reaction between silver and hydrogen sulfide. what occurs during this reaction?

A. A double-replacement reaction takes place
B. An acid-base reaction takes place.
C. silver atoms Gain Electrons from sulfur atoms.
D. Silver atoms louse electrons to sulfur atoms.

Answer 1

2Ag + H₂S ⇒ Ag₂S + H₂

Ag ⇒ Ag⁺

Silver atoms loose electrons to sulfur atoms.

Answer 2

Answer:

Option D

Explanation:

The reaction is given by

• Ag+H_2S—»Ag_2S+H_2

In the reaction

silver loses two electrons to sulfur in atoms inorder to attain Ag²+ structure .

As loss of electron is oxidation it's redox reaction
