[15 points, hlp]
complete the half equations by balancing it and identify as either oxidation or reduction.

cl^- (aq) → cl2 (g)

f^- (aq) → f2 (g)

s (s) → s^2- (aq)

h2 (g) → h^+ (aq)

o2 (g) → o^2 (aq)

The half reactions are given below.

Explanation:

Oxidation reactions are defined as the reactions in which a chemical species looses its electrons. The oxidation state of the specie increases.

Reduction reactions are defined as the reactions in which a chemical species gains its electrons. The oxidation state of the specie gets reduced.

For the given reactions:

1.)

Here, the oxidation state is getting increased, therefore it is an oxidation reaction. The equation for this follows:

2.)

Here, the oxidation state is getting increased, therefore it is an oxidation reaction. The equation for this follows:

3.)

Here, the oxidation state is getting reduced, therefore it is an reduction reaction. The equation for this follows:

4.)

Here, the oxidation state is getting increased, therefore it is an oxidation reaction. The equation for this follows:

5.)

Here, the oxidation state is getting reduced, therefore it is an reduction reaction. The equation for this follows:
