Question

Which of the following are redox reactions? For those that
are, indicate which element is oxidized and which is reduced.
For those that are not, indicate whether they are precipitation
or neutralization reactions.

Hey everyone. We're asked to determine the statement that is true for the following reaction. Looking at our answer choices, we can see that. We're talking about the type of reaction. Now we can go ahead and determine whether or not this is a redox reaction first by looking at our oxidation states. Starting with our carbon in our methane, We know that this will have an oxidation state of negative four Due to the positive four on our hydrogen. Next looking at our oxygen's, our oxygen in our reacting side is going to have an oxidation state of zero since it's in its standard state in our product side. Looking at our carbon dioxide, we know that oxygen has an oxidation state of negative two and since we have two, oxygen's our carbon must have an oxidation state of positive for To summarize our carbon went from an oxidation state of -4 to positive four And our oxygen went from an oxidation state of 0 to -2. And thinking back to one of our new Monix oil rig, we know that oxidation is going to be loss of electrons while reduction is going to be the gain of electrons. Looking at our carbon, we can see that our carbon was oxidized since it lost electrons while our oxygen was reduced. Since it gained electrons. Now checking our answer choices, it looks like c is going to be our answer since it states that the reaction is a redox reaction where the oxygen is reduced and the carbon is oxidized, which is exactly what we stated. So I hope that made sense. And let us know if you have any questions.
