**1. I need to find the element being oxidized and reduced for:**

CO2 + C = 2CO

I don't know how to do it for this one.

CO2 + C = 2CO

I don't know how to do it for this one.

3. I know how to do it for ones like this:

2Al + 3Cl2 = 2Al(3+) 6Cl(-)

it would be

zero for elemental Al and Cl

and the oxidation number for the product would be its charge.

but how do I do it for ones like this.

CO2 + C = 2CO
