you are singlehandedly saving my chemistry grades omg
I feel like this channel is slightly overshadowed by freesciencelessons, which doesn't make sense because they are both equally amazing. Thank you so much for all the work you do to help us!

I think FSL has existed for a bit longer than Cognito so they get more views... but I honestly prefer Cognito.

Thanks Cierra! Really happy to hear you like them :))
my teacher took 40 mins to explain this ur teaching is amazing and simple ty sm
Bros back probably hurt from carrying all our grades
A huge thank for these videos! I am a mature student, hoping to start a Nutritional Therapy Degree next year. I don't have a science A' level so am working through a science access course and your videos have proved to be so helpful. Short enough to hold my attention but detailed enough to cover the necessary content. The animations are really good too! I wish you'd been around in the 80s when I was at school!
i have a chemistry mock exam in two days for my o levels, and im using ur channel to understand some concepts that i dont get. thank you so much, ur saving lives!!
This is very helpful! Thank you so much!!! 🙏🏽
What will I ever do without this channel
this makes soooo much more sense, thank you for enlightening me :}
These videos are literal life savers ❤
you're literally saving me right now, i have a test tommorow and i could not be more grateful

Hi your videos are extremely helpful so thank you! I just wanted to ask, is there any particular topics /questions I should focus on for science? I have my mocks on paper 1 in a week and it'd be very helpful to know what topics I should focus my revision on. Thank you so much!!!!!

Hi. one quick question, why do you write ethane as C2 H4 instead of C2 H6
@ashtonmiller1186
2 жыл бұрын
ethANE is an alkANE the general formula of alkanes is CnH2n+2, but on 4:48 the screen shows the product ethENE which is an alKENE hence their general formula is CnH2n so C(2)H2(2) = C2H4

Can I ask why in 3:11 it must need to be (7xC) + (3xC)? Why can't it be (6xC) + (4xC) or others??
