I wrote down the explanations, hope this helps!!!!

✅Chemical reactions often involve changes in energy due to the breaking and formation of bonds. Reactions in which energy is released are exothermic reactions, while those that take in heat energy are endothermic.

Answer:
3 mole O2
Explanation:
Need balanced equation first: O2 + 2SO2 --> 2SO3
assuming SO2 is in excess,
1.5 mol O2 (2moles SO3/1mole O2) = 3 mole O2
Answer:
The correct answer is option B, that is, CO + H2O → H2 + CO2
The redox reactions are regarded as the chemical reactions in which one reactant goes through the process of reduction and one reactant goes through the process of oxidation. The reduction reactions are the reactions in which gain of electrons occurs, while oxidation reactions are the reactions in which loss of electrons occurs.
From the mentioned options, only option B, that is, CO + H2O → H2 + CO2 is a kind of redox reaction. In this, the carbon is getting oxidized from +2 to +4 oxidation state, and hydrogen is getting reduced from +1 to 0 oxidation state. Hence, this reaction can be regarded as a redox reaction.
