I fucking love you, my teacher is so bad but I just watch your video and understand it

Youre a miracle, i would watch your vidoes if they were 2 hours long

When you add up all the "MOLE FRACTIONS" does it always equal to 1? Anyone? Thanks

[tahajawad]

How happy does getting that last answer correct make you! Love you passion!

[sujata]

Best videos out here for a level chem, thank you, sir!

[debster]

Love this guy!! Your videos are really helpful thank you so much fir uploading them 😍😍😍 i bet your students love you for the resources

[ramboedah]

I’m sure that changing pressure affects the value of Kp, if you do your calculation at the end again with a different pressure then the value for Kp changes.

I was laughing my ass off at the end 😂😂😂

Great video!

[jacobsuresh]

it feels illegal to watch these for free

Great video! Just one thing, at roughly 9:30 when you found out the no. of moles of all the gases, I don’t understand how you go from 2 moles of PCl5 to 3.25 total moles. Where did the extra 1.25 moles come from. I know my understanding of what moles are is probably completely off, but I’m trying to self-teach in coronavirus lockdown, if someone could help it would really be appreciated! Thanks
