Answer:

One is tension force that acts on the string and the other one is gravitational force that is acting on the pen and is therefore, the one that pulls the pen towards the ground. Therefore, the pen's motion is caused by the unbalanced force acting on the pen.

2Ag (s) + H2S(s) → Ag2S(s) + H2(g)

Advocard [28]

Answer: Oxidation half: $2Ag\rightarrow 2Ag^++2e^-$

Reduction half: $2H^++2e^-\rightarrow H_2$

Explanation:

Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

$2Ag(s)+H_2S(s)\rightarrow Ag_2S(s)+H_2(g)$

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

Oxidation half: $2Ag\rightarrow 2Ag^++2e^-$

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

Reduction half: $2H^++2e^-\rightarrow H_2$
