Thank you Leah, recently ran into your youtube and wanted to thank you for such informative videos. Although I am not sitting the MCAT, I am sitting the GAMSAT (similar, just an Australian version) and these videos are highly relevant.
The rules state that the sum of all oxidation numbers in a neutral compound should be zero (see #3 on my list). Since CO2 is a neutral compound, the total of all its oxidation numbers should be zero. Oxygen, by itself, typically has an oxidation number of -2. Other atoms in a compound with oxygen will have to adapt their oxidation state to fit the oxygen. That’s why carbon in CO2 ends up with an oxidation number of +4.
Could you be more specific about what you don't understand? I address this topic at 8:45 in the video. The peroxy ion is composed of two oxygens single bound to each other, where each oxygen atom has an oxidation state of -1. In H2O2, the hydrogen atoms would each have an oxidation state of +1.
Thank you, one of the most clear explanations of this subject I've seen.
You're very welcome!

You are so welcome! I have quite a few GAMSAT students I work with, glad to help!
So clear and easy to understand, Thank you
You are welcome!
Great video! Thank u!
Glad you liked it!
this is fantastic
Thank you, glad you like it!
Thank you ma;am for upload this video and make me to learn easy. THANKS A LOT. I am from Nepal.😎😎😎😎
Glad you liked it! You're welcome.
Thank you
You're welcome
thanks for explaining
You're welcome!
Thanks for sharing this. Can you explain redox balance in biochemical reactions?
Stay tuned!
I am from India ...thank u so much
you're very welcome
Why in the CO2 you equal it to 0 then in oxygen you used -2 I dont get it

@@Leah4sciMCAT thank you😁
wait how would you do H2O2, i don't understand peroxy

You are good
thanks!
thank you
you're welcome! :)
Thanks teacher can you expansion in this
