Hello! When calculating the Kh for oxygen, i got 777 instead of 769. Can you explain your process?

[@silverhey9474]

Seriously you are the best teacher ever. thank you SOOOOOOO much. all your videos are so good at explaining things

[@felixsunrise]

All your videos are great, thanks for helping me out !

[@stanleysu8812]

Why is C on bottom and not on top?

[@humanabeel440]

Wow! Thank you so much for saving me in medschool! Your explanations bring me joy. Thank you Dr. Rishi, love from Pakistan

[@DeepSeaDog]

Another Great Video! What technology are you using to draw all of these examples? I might want to invent in it for my classes.

[@UltraSidefx]

makes so much sense...thank you very much

[@gt4941]

c=kp not p/k

[@EpisisTune]

Thank you for enlightening me

[@feetlessdance]

Ok. I've watched your other videos, and you're really good at simplifying concepts. 👍 But I need to make a few corrections here. Firstly, the Kh of CO2 is higher than O2. And the Henry's law is C = Kh x P, not P/C = Kh. 🤓 When the CO2 Kh is higher than the O2, the concentration/solubility will be higher too, according to that equation. Correct me if I'm wrong! 😊

How did he find the partial pressure??

[@SallyCarly]

helps a lot in understanding thanks !

[@jennylim6769]

how do you get the Kh?? is it .21/.27...?

I think percentage of carbon dioxide in the atmosphere is very low, about less than 0.1%, NOT 21%.

[@eragon2121]

+Momin Khan He says that in the video.

[@sule4240]

He said that the percentage of O̲X̲Y̲G̲E̲N̲ in the atmosphere is 21%

Show your work so you dont confuse the fuck out of everyone next time

You have low iq. Not fit for science forget about medicine. Do humanity a favor and take non science path

This is wrong

How on earth did this guy test that oxygen had dissolved in the water? imo oxygen is hydrophobic and doesn't dissolve in water. Fill a plastic pop bottle with a little distilled water then fill the head space with oxygen gas. Once filled, tighten the cap and shake vigorously. If oxygen gas dissolves in water one should observe a collapse of the pop bottle. That is not observed unfortunately; the integrity of the bottle remains. The video's content is so fake!

[@feetlessdance]

Oxygen is Hydrophobic? Where did you get that from. Oxygen does dissolves in water. Where do you think Fishes get the Oxygen from ? O2 cylinder?😅.

[@PeterPete]

@@feetlessdance quote - Oxygen does dissolves in water. that's funny! Whenever I bubble oxygen gas through water it alwasy rises to the top!! In fact the only gases I've actually watched dissolve in water are CO2 and chlorine!! I'm sure there are others but oxygen?? I don't think so!! Try filling an empty plastic pop bottle with some water and then fill the head space with oxygen. Then close the stopper tight. Now vigorously shake the bottle for at least 5 minutes. Then tell me if you notice any collapse of the bottle!! If oxygen dissolves in water then one should observe a collapse of the plastic bottle!! Btw I've already done it and the bottle did not collapse! But have a go yourself as you're not going to trust my word are you?

[@PeterPete]

@@feetlessdance try filling a plastic pop bottle with a little water and fill the remaining head space with oxygen. Close the top tightly. Now shake vigorously. Will the bottle collapse because oxygen has dissolved in the water? I've already done it. Now you try! Instead of oxygen also use air and CO2 as a comparator 👍
