The 'whole of the topic in … minutes' videos DO NOT comprehensively cover everything you need to know for your exams. It would be impossible to include 2 years of teaching in 1 hour. These should NOT be your only source of revision • Do the 'whole topic in... My exam predictions are just GUESSES!! I don't have any insider knowledge just years of looking at exam papers.

Thank you !!
Lord Mang0 why focus on that but when you can focus on the fact he helped us ☺️
omg you did this on the last video i watched, i actually love you
Pin this!
Thank you, you are making my revision an absolute dream!!!
For percentage yield, you have to times by 100 after dividing the actual and theoretical yields from one another, to actually get the percentage
Bro she spelt Percentage Yield wrong
i got u now i got 65 i my mocks thanks to u
Amazing - that's down to your hard work and commitment too!
omg thank you, I compiled a list from my notes of things I didn't understand at first glance I've learned all that; and due to poor performance in the quantitative section of my chemistry mock, I'm here a day before my exam trying to learn it!
good luck :)
LaFadeAway thanks! you too?
Ayy, at least I’m not the only one, good luck lol
This was super useful!!! Thanks so much and big up everyone who is doing their revision for 2021 exams through the hard times
✌️✌️
This is the morning of my mock kms
Thank you so much, I needed to learn quantitave chemistry before I go to school tomorrow. This honestly helped me out a lot.
Thanks 🥺

amen
We did this topic during quarantine and I didn't understand a single bit, but you make it look so easy! Thank you!!!!
My gcse are in 3 years. Already started preparing
bro u havent even started your gsce course lmao
Bro enjoy life ffs why
At 5:21 it's not 6x10^23 it actually is 6.02x10^23.This is for accuracy marks.
Harry Patel do I have to remember that?
Daniela Nastuta yeah
this is so minute.
actually its 6.022x10^23
@@bertiee3701 Actually, in the exams, for GCSE, they tell you to use 6x10^23
People who have their chemistry paper today ------>
Yay, mock tomorrow but I’m not actually feeling too stressed. Thank you!!
Good luck!!
Hey miss
I appreciate u r very busy doing awesome stuff but i was just wondering when the other whole topic videos will be out for aqa chemistry
Thank u for all your help😊😊
ASAP!!
i thought when you calculate the Mr you don't use the co-efficents (the large numbers)?
Priya Dutt yeah you dont
Same I am confusionnn....
You use the big numbers to find out how many atoms of that element there are. For example 2H would mean there are two hydrogens so you would multiply Hydrogens AR by two
@@alishahussain554 so she shouldn’t have done that for this?
Chemistry GCSE paper 1 tomorrow.. this is going to hep a lot!
Yeah.I'm failing science for sure :D
I’m doing your gcse now as a mock so any help?
This was really helpful & a great way to re-go over this topic as we did it last year so thank you! ☺️🐱
Thanks so. Much I really need this
Literally got an exam in a few hours doing last min revision😭
i have my mocks in abt 30minutes and i am omw to school right now while doing last minute revision. good luck to all who are doing tests
Measure mass or volume of a reactant by collecting products in gas syringe or balance
Degree of uncertainty
Concentration: amount divide by volume
Moles/dm3 =moles volume
dm3
Holy cow this is useful
2022 squad where are you
😭😭😭
Oh god
This was so helpful! Thanks so much :)
This was really helpful, thank you!
For reacting masses the method you showed us can i use that for any other question?
WTF DOES ANY OF THIS MEAN I HATE CHEMISTRY SM I CANT DO THIS ANYMORE
FR IM GONNA CRY
can someone explain why at 2:46 chlorine gets 2 ?
This is so boring how do people want to do this
just wait until you see how long hte A-Level version are!
Mock tomorrow thank god I’ve found something good for it!
I dont understand shit
Thanks for the help!
*6.02x10(power of)23
Mock tomorrow 😫😢
thank you
so helpful thank you
2:21 how do u know that it’s salt and how do u know if they are +2
last minute revision before chemistry end of year exam-
is this useful for foundation??
Hi Caitlin Anne, this covers both the content for combined science and separate science at both foundation and higher tier. If you're not sure which bit is which then I suggest you get my FREE revision guide from my website www.primrosekitten.com/collections which has everything clearly laid out for you
GCSE Chemistry tomorrow
hi does combined science students need to revise percentage yield and atom economy? and thank you so much for all the work you put in, I went from 5s to 7s and its all thanks to you!! so thank you so so much.
Hi Uke, this covers both the content for combined science and separate science at both foundation and higher tier.

The dislikes are from the brain boxes
yield was spelt wrong I'm pretty sure theoretical was spelled wrong too also percentage yield duhhh its percentage so you would have to times it by 100!!
Hi Angelica A, making these videos takes a lot of time and effort, I do this so I can help as many students as possible achieve the best grade they can. I'm sorry you don't find my channel helpful. I struggle severely with dyslexia, this means writing such long videos, with long complicated words in, is extremely difficult for me.

Oh I’m sorry, I do find your videos extremely helpful the spellings mistakes are just a pet peeve . ❤️❤️
Watch out with atom economy - it's not just the relative Mr of the substances in the formula. You need to take account of the balancing numbers as well.
For some people a mole may be 6.02x10 to the power of 23 (just saying this so you guys don’t make a huge mistake)
wait for titrations what indicator do you use?
you can use methyl orange or phenolphthalein
For the percentage yield wouldnt you have to time it by a hundred afterwards if you want to get the actual percentage?
Yep!!
This lady can discuss a whole topic in twelve minutes my teacher takes 2 hours
I think you just saved me from failing GCSE chemistry lol
The hydrogen peroxide part....i get the whole balancing but then i dont understand why youre multiplying / adding / dividing etc someone explain please. Is there an equation or formula that goes with it?
cici dilaurentis because the question asks how much oxygen is given off from 40.8g of hydrogen peroxide so you have to workout how much oxygen is given off as a product
thanks
You're welcome!
2:51 how do you know how many ions are in them?
is this triple higher?

@@Primrose_Kitten Alright, thanks for the workbook links :)
my end of year is tomorrow
Percentage yield = actual yield/theoretical x100
thats what i was thinking
Why so quiet?????
Nice
no bc my chem exam starts in 10mins
** yield not yeild - but anyways v helpful - im so scared for my mock- in 2 hours !!!!
Can I use this for triple science higher?
You spelt 'yield' wrong
