Thank you so much for this video, I have struggled with chemistry the most out of all the sciences. I need a grade 8 or 9 as I’m doing in next year and I really appreciate all your help, thank you!
3 means 3 moles of oxygen, 3.5 moles means 3 and an additional half of a mole. (1 mole = 6.02*10^23 atoms, so half a mole would be 3.01*10^23 atoms.) btw, you can multiply all the number of moles in both sides of the equation by 2 so that all of them are whole numbers, this would still be balanced correctly as the ratio is still the same, and it makes it easier to look at. I hope this helps :)
I finished my chemistry paper 2 today and this video was a true gem for me ! it helped me understand GCSE Chemistry like never before. thank you for making complex topics so clear and easy to grasp ❤️
Hii I do separate science and I'm not going to lie, yesterdays paper was really difficult but i am glad i watched your video because if i didn't, i would have failed. Guys, these videos work and they are WORTH IT.
THANK YOUUUUUUUUUUUUUUUUUUUUUU, i got 9s and 7s in all my previous mocks simply by listening in lesson and watching your videos to revise and I'm so thankful you're putting out videos during exams, rly hoping for a 7-7 thank you again!!!!!
Thank you so for all your hard work, biology went great due to your video! I am just wondering what topics are single only a I do combined and don't ant to waste any time. Thank you again!!!
The molecular formula increases by CH_2 everytime as you go down the homologous series. I think idk. ahaha For example in alkanes: Methane = CH_4 Ethane = C_2H_6 Propane = C_3H_8 Butane = C_4H_10 etc..... NOTICE HOW THE NUMBER OF CARBON ATOMS ALWAYS INCREASES BY 1 and THE NUMBER OF HYDROGEN ATOMS ALWAYS INCREASES BY 2 This is the same in alkenes: Methene = (non - existant) Ethene = C_2H_4 Propene = C_3H_6 Butene = C_4H_8 Pentene = C_5H_10 etc..... This is also the same in alcohols: Methanol = CH_3OH Ethene = C_2H_5OH Propene = C_3H_7OH Butene = C_4H_9OH Pentene = C_5H_10OH etc..... HENCE THE MOLECULAR FORMULA OF SUCCESSIVE COMPOUNDS INCREASES BY CH_2 I hope this is right and this helps ahahha

alkenes are unsaturated 36:09
Thank you so much ☺, Chemistry is my favourite Science subject, but doing combined science and history is my priority. This will really help!
how
When is the physics paper video coming out???
Here! ruclips.net/video/MgUQ5btzxuE/видео.html
last minute gang?
Are we cooked?
I revise 30 mins before the exam 😔
I HATE SCIENCE THE ONLY THING I CAN DO IS BIOLOGY ISTGG
@@JE_sui hopefully AQA nice us like they have done so far
@@unknown_kingzzz4120 they cooked us on biology paper 2 so what's to say they won't cook us on chem paper 2
Thank you so much for this video, I have struggled with chemistry the most out of all the sciences. I need a grade 8 or 9 as I’m doing in next year and I really appreciate all your help, thank you!
Good luck!! You're so welcome
hope you got that grade!
i believe there is a mistake at 36:30 as alkenes are unsaturated while it is alkanes that are saturated

very helpful thank you so much for all your hard work it is very appreciated!!!!!
Hi when’s physics being released and tyvm for these vids
hi, i think there may be a mistake at 48:15 with the carboxylic acid structures!
defo
where r the last minute ppl💀
Bro I'm cooked I want a 7 and I'm doing revision the night before 😭😭😭
@@JE_sui same bvri
@@JE_sui bhahahaa same lmao
meeee
omg tysm for the video. all your grade 9 videos are so helpful
You're so welcome!
thankyou for making it this long this is how you know you really went through it all and i really needed this
You're welcome!
Hi will you be uploading physics aqa higher too? because your videos so far have helped a lot!!

hi thank you very much for your videos
@43:37 what does the 3.5 mean? Should it not be 3? Is there something wrong with my understanding?
ty
3 means 3 moles of oxygen, 3.5 moles means 3 and an additional half of a mole. (1 mole = 6.02*10^23 atoms, so half a mole would be 3.01*10^23 atoms.)

Aww this is so lovely!! Can't wait to pass this on to our Chem teacher ☺
you saved my biology paper 2 🙌🙌
36:17 alkenes are unsaturated
Thanks for this :) do combined science have to know the different products of fractional distillation??
no
do I have to remember the Diols and dicarboxylic acid things or was it just used as an example??
best to just memorise it just incaseee
remember
it
can u post the physics paper 2 tomorrow

WIll physics come out tomorrow? These videos have saved me
Here you go! ruclips.net/video/MgUQ5btzxuE/видео.html
@@Primrose_Kitten Thank you so much
Hello, Thankyou for doing a rundown on p2 chem but I think there's an error alkenes are unsaturated
cheers
im so grateful, i honsestly don't know what ill do without your videos💜💜💜
Well done - you've clearly been working so hard. Thank you for the feedback 😀
Thank you so much for posting all of these, they’re so so helpful! Really appreciate all the effort you put into these. I love youuu 💕
You're so welcome!

to cook or to be cooked
cookkkk
Be cooked
Good luck!!
YESSS this is what I’ve been waiting for 😍😍👌🏻
Hope it's useful 😀
Thank you so for all your hard work, biology went great due to your video! I am just wondering what topics are single only a I do combined and don't ant to waste any time. Thank you again!!!
updated the timestamps for you!
Thank you, hope it wasn’t too much of a pain
Chat im revsing the night before the exam and i want a 7/8 am i cooked???
thank you for this video! are you making a predicted paper?
yh it's already on her website like 1 pound or somt
so would i be okay if i watched this video only as revision?
I mean you wouldn’t fail
do some practice papers too
when will u post the physics paper 2 one
Here - ruclips.net/video/MgUQ5btzxuE/видео.html ☺
alkenes and their formula are in combined sci too
can you pls make same video for physics? this video absolutely helped me! thank you!!
Yes, soon
@@Primrose_Kitten will it be released today, please?
ruclips.net/video/MgUQ5btzxuE/видео.html - here!
Is this triple??
It's everything
Yes all of the topics are for triple (including Separate Chemistry ) i think
i thought this was about a levels until i saw the grade 9 and i was incredebly thankful that i didn't click the wrong video
i dont usually comment but your very helpful thank you!
Aw so lovely. Thank you!
Thank you so much!!!
No worries!
Please do a predictions video for chemistry topics
Thank you, that was helpful albeit boring.
At this point in exam season, it's all just dull now. You're nearly there!!
I'm doing some really last minute revision here, 49 minutes before the exam. First time revising this for a while. Bad idea
waiting for physics

Physics soon?
ruclips.net/video/MgUQ5btzxuE/видео.html - here!
organic chemistry might end me
Is this for triple higher?
it says which topics are triple!
yes it tells you when a topic is just for triple chemistry
Letsss goooo
💪
A few mistakes in organic reactions
could you please do ocr a triple
higher

27:52 can somone explain the 2nd bullet point
The molecular formula increases by CH_2 everytime as you go down the homologous series.
I think idk. ahaha
For example in alkanes:
Methane = CH_4
Ethane = C_2H_6
Propane = C_3H_8
Butane = C_4H_10
etc.....
NOTICE HOW THE NUMBER OF CARBON ATOMS ALWAYS INCREASES BY 1 and THE NUMBER OF HYDROGEN ATOMS ALWAYS INCREASES BY 2
This is the same in alkenes:
Methene = (non - existant)
Ethene = C_2H_4
Propene = C_3H_6
Butene = C_4H_8
Pentene = C_5H_10
etc.....
This is also the same in alcohols:
Methanol = CH_3OH
Ethene = C_2H_5OH
Propene = C_3H_7OH
Butene = C_4H_9OH
Pentene = C_5H_10OH
etc.....
HENCE THE MOLECULAR FORMULA OF SUCCESSIVE COMPOUNDS INCREASES BY CH_2
I hope this is right and this helps ahahha

Morning!!
last last minute gang (cooked)
Haha fools I am last minute-er
Messed up the structure of carboxylic acids at 48:17 🙄🙄
is the video one wrong
@@faatimah6420yeah look at ethanoic propanoic and butanoic acid they have the same structures in the video but the formulas are completely different
