I’m gland that I found this amazing teacher when I was in hard times in grade 11 2023 and I’m still stuck on him 2024 in grade 12 and I’m always getting higher marks ❤❤
Regarding the Maxwell Boltzmann curve. If the temperature is decreased the curve shifts to the left. This would result in a decrease in the area under the curve if the peak of the curve remains the same. Note the area under the curve represents the total average kinetic enegry of particles. Therefore in order for the area under the curve to be the same - the peak must increase to allow for the total average kinetic energy to be the same. Remember energy must be conserved due to the energy conservation principle. Also the peak would increase since more particles would have a KE closer to the average kinetic energy which is the peak. Because the standard deviation would be lowwer. Just some statistics knowledge. Math is useful for science guys. And to have the same number of molecules/particles your peak would have to be higher. Since the curve is narrowing and the peak remains the same it would mean there's less molecules/particles.
Am i the only one who studies everything using Kevin's videos before the teacher even introduces everything?but still get straight level 7s?😂😂#kevinforpresident
We are looking for the mass of CO3 so that we can calculate time blah blah blah, but at the same time we don't know the number of moles of CO3 but we are told the mass of MgCO3, can you notice that, that MgCO3 is on the balanced equation? We can use it to find the number of moles of CO3 by calculating its moles first then use moles ratio to find moles of CO3....so we are using MgCO3 because we are told about its mass, this means that if we were told about anything on the balanced equation besides MgCO3, we were gonna use it...USE WHAT YOU ARE GIVEN
the 0,5 is 0,5g.min^-1 which is reaction rate. the 0,0595 is the amount of moles of CO2 used. He had to use the moles (0,0595) because of the formula n = V/Vm
I am writing my final paper of Chemistry tomorrow, and i feel confident after watching these videos.
Thanks Kevin
brotha dont keep ur hopes up
@Lost_soul78 I will keep my hopes up
@t.kchannel1732 keep your hopes high you got this❤only believe in yourself don't panic

It took Kevin 9 minutes to finally give us the answer😭😭
Day before final exam 😂
Same here😭😂
Location 😭
Yohh😂
Writing tomorrow so anxious😢😢😢😢
To Those that are here in 2025, dont worry Chommi, Kevin is the TRUTH!! You are in good hands❤😊
Prove you watching this before the day you write your prelims Exam tomorrow 😭
Tomorrow im writing😂
😭Eish
O slege u right😂😂😂😭
Yebanna😂😂😂😂
and i still have organic chem to cover 😭😭
Literally writing in a few hours 😢, which me luck
Kelvin you are really sent from heaven 🙌🙌🙌
not me tryin to watch all the videos to make up for tommorow😂
Same😭
Same😭
😂😂😂
Same😢
Writing on Monday😭✋️
Come on the teacher is calling me 😭😭
Bru said I must wait
Not me coming here the day before my exam
"my bro, my home dog" killed me 💀
Bro is casually making jokes while I study for my life😂
Effective collision 🤣😁 I like how you explained that
😂
Really helpful, thanks Kevin ❤ you're highly appreciated

gosh why am I here the day before my exam again
Yoh Kevin I think you need the chill pill 😂relax broo
Hey mr Kevin. May you please make more videos on this topic
hello kevin!
please do more videos on this topic or add more questions
Cooked is all I can say 😔😭
No because SAMEEEEEEE 😪the examiners of 2024? Mxm
Thank you sir , please do 1 hour videos for each topic like you did for organic chemistry
Am i the only one who studies everything using Kevin's videos before the teacher even introduces everything?but still get straight level 7s?😂😂#kevinforpresident
u the only one
Coooked😔✋️
Bro😢😂
Shout out to kevin😭🫵
Don't worry ur not alone😭😭😭😭😂😂

We are here 😅😂
@@hazel_eyed_sasha it's really going down😂😭

Writing in few hours an this is new to me
Same😭
real
how did u do
Thank you so much for this video. It really helped.❤❤
Here the day before exams 🤣🤣😭😭
kevin you the GOAT !
Writing tomorrow 😭😭
How did u write
Ehhh phukie 🤣🤣🤣🤣

we all are
writing in 3 hours I'm cooked😭

😂For reasons that goes way beyond grade 12 level
Kevin 5.4.1 you needed to calculate the time at completion which is 43°=0,6g•min^-1 instead you calculated the time at 40°
Does anyone know why at 19:01 he uses CO2 instead of HCl
We are looking for the mass of CO3 so that we can calculate time blah blah blah, but at the same time we don't know the number of moles of CO3 but we are told the mass of MgCO3, can you notice that, that MgCO3 is on the balanced equation?

kevin for question 5.4.1, why did we calculate the time in accordance to the CO2 gas produced?
For the collision theory questions [4 marks] does the order of our points matter?
4 hours before the exam and im here😂
Writing tomorrow I know I'm gonna fail just gonna try get code 4 minimum 3😅
how did it go?
Im cooked tomorrow 😭
Same dawg🙏😭
@@slasher4642 time paper 1 chowed 😭
Im only starting now...its 23: 42pm
why are we using 0,0595 instead of 0,5 since we're at 40° 23:54
the 0,5 is 0,5g.min^-1 which is reaction rate. the 0,0595 is the amount of moles of CO2 used. He had to use the moles (0,0595) because of the formula n = V/Vm
Now I understand collisions
Guys who else is studying before term 2 😅

day before the final TT
was kinda sus
Life sciences messed up my mind 😭😭😅😅 6:33
