Thank you, one of the most clear explanations of this subject I've seen.
You're very welcome!
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.
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!
thanks for explaining
You're welcome!
Thanks for sharing this. Can you explain redox balance in biochemical reactions?
Stay tuned!
Thank you
You're very welcome
thank you
you're welcome! :)
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.
I am from India ...thank u so much
you're very welcome
You are good
thanks!
wait how would you do H2O2, i don't understand peroxy
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.
Thanks teacher can you expansion in this
The free videos are what I do as I have time. For more help with this topic, feel free to contact me through my website: leah4sci.com/contact
Why in the CO2 you equal it to 0 then in oxygen you used -2 I dont get it
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.
