Question

Questions balance the following redox equations

Answer 1

\[Fe ^{2+} + O_{2} \rightarrow Fe ^{3+} +H_{2}O\]

Answer 2

So essentially Fe is oxidized because it's oxidation state increases by one
and water is oxygen is reduced because it goes from an oxidation state of 0 to +1 in water.

so essentially this means electrons are going from Fe to Oxygen

Answer 3

so Fe is being oxidized in the process and causing oxygen to be reduced, so it's the reducing agent.

while oxygen is being reduced while causing the iron to be oxidized. Oxidizing agent.

One of my questions is that is this a spontaneous process or non spontaneous process and how do we know?

Answer 4

Here are the half reactions I did. @rushwr
