Answer: Oxidation reaction: 
Reduction reaction: 
Overall redox reaction : 
Explanation:
Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.
Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.

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

Overall redox reaction : 
The new volume of the balloon : V₂ = 4.89 L
<h3>Further explanation</h3>
Given
V₁ = 4.96 L
T₁ = 6 + 273 = 279 K
T₂ = 2 + 273 = 275 K
Required
The new volume
Solution
Charles's Law
When the gas pressure is kept constant, the gas volume is proportional to the temperature

Input the value :
V₂=V₁.T₂/T₁
V₂ = 4.96 x 275 / 279
V₂ = 4.89 L
Correct, it is a start of a experiment, something that is asked first.
