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!
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!!
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!!!!!
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
this is exactly what i dont understand and what causes me to struggle, its been 1 month since you wrote the comment, do you know maybe now andd could explaine it to me pls ?
