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.

[@Leah4sciMCAT]

You are so welcome! I have quite a few GAMSAT students I work with, glad to help!

[@tmujir955]

Thank you, one of the most clear explanations of this subject I've seen.

[@Leah4sciMCAT]

You're very welcome!

[@lovesharma1000]

Thank you ma;am for upload this video and make me to learn easy. THANKS A LOT. I am from Nepal.😎😎😎😎

I am from India ...thank u so much

[@Leah4sciMCAT]

you're very welcome

[@sgrinev]

Thanks for sharing this. Can you explain redox balance in biochemical reactions?

[@Leah4sciMCAT]

Stay tuned!

Why in the CO2 you equal it to 0 then in oxygen you used -2 I dont get it

[@Leah4sciMCAT]

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.

@@Leah4sciMCAT thank you😁

[@RahulKumar-it2te]

thanks for explaining

[@Leah4sciMCAT]

You're welcome!

[@ninetofivefivetonine7765]

wait how would you do H2O2, i don't understand peroxy

[@Leah4sciMCAT]

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.
