I thought paper 1 was hard, then came paper 2😭let's see what paper 3 will bring😨

[@michaelc6294]

Both paper 1 and 2 were way harder than what I expected lol. Paper 3 is my worst paper so I doubt I’ll even get a C in chemistry overall

[@niallmoseley6760]

I don't understand , where are you meant to get the knowledge for the practical question?Is it in the book. We did the required practicals but never in that much depth .

[@Jamesclass37]

Niall Malik the required practicals are where the info comes from. You should have done your write ups so you need to read over them.

[@goldenmonkyz]

literally type on youtube aqa a level chemistry practicals and a guy called chris clay has covered all 12. I'm in the same position as you

[@HS-ii9dj]

Would you be able to do the Edexcel Chemistry paper 3 2018 paper?

[@richi27102]

apparently when you work out percentage error for burettes and balances,you have to multiply by two because you take two readings. That's what my teacher said atleast. So I am confused as to why he didn't actually 0.15/3.98 x 100 x 2 which would actually give a %error of 7.5%. Perhaps that might be a marking strategy that's unique to Edexcel but still I wonder.

[@jamesoliverlang]

FIRST!! Notification squad also thanks for saving my A-Levels 1 video at a time

[@krepes8685]

Shouldn’t the percentage error question be doubled as your mean titre has come from two calculations?

[@bobbradley5331]

Krêpes no it should be but I asked about it and someone who does mark schemes says don’t do it

[@bijjuu2]

Great Video . Can you please help me with question 2.1 (17:42). How is number of moles of ethyl ethanoate and water produced is same as the number of moles of ethanoic acid reacted but not as same as number of moles of ethanol reacted. And how can we calculate the concentration of each reactant and products when the volume of reaction is not given.

[@wfk2757]

Here I am panic revising the night of, good luck everyone!!

for Q4.2 why cant HC2O4 - has the value 1*10^-1?

[@trigerhiger]

Youre the definition of a life saver

[@leolion12345101]

For question 15 you dont have to any calculations all you do is check which one is 3 significant figures (e.g B, or D) and which is in correct standard form (e.g A, B, or C) so it must be B.

[@ibby6628]

question 2.1 better not come up..... maths better not come up unless it asks to do an additon....

[@niloufarjamali1705]

Great videos!! Could you do paper 5- the planning and analysis paper in A2? :)

[@riadhossain1001]

Hi sir, where can i find revision resources for these specific topics in this specimen 3?

[@rrockchick1]

Hi can some explain how they worked out question 9 please? :)

[@SuperCalmCrew]

Popcorn 1 n=m/mr n= 2.01*10^-5 mg2+ mol also equals this because 1:1 ratio in equation. c=n/v dont forget to convert cm^3 to dm^3 by dividing volume by 1000 c=2.01*10^-4

[@rrockchick1]

Thanks :)

[@nedafinil]

12:40 shouldnt the sodium carbonate test be done before the tollens reagent test? because if it was done afterwards then there would be fizzing as the reagent will have oxidised the ethanal into ethanoic acid

[@georgey6423]

they asked what tests could be done, so you list the ones that could be done, this doesnt mean that you are doing all of them, just listing the possible ones. I used to think that as well but teacher said they only asked for the ones possible, you are not doing all to same mixture

[@blightX9]

Isn't question 26 3? Because the 4th one is the same as the third one?

[@tombates8741]

is the test for a carboxylic not sodium hydrogen carbonate?

[@sam-cn8tu]

Yeahh that's definitely one way

[@Sky-ez5wp]

why would anyone dislike this

[@zm7169]

for q.2-01 when working out moles of ethanol why is is (1.2×10^-1) - 6.40×10^-2 and not (1.2×10^-1) - 0.016

[@TheGemRobin]

0.016mol are the moles of ethanoic acid that are left at equilibrium, so (8x10^-2) - 0.016 = 0.064 moles have reacted. That means 0.064 moles of ethanol have reacted because the ratio of ethanoic acid : ethanol is 1:1, so you have 0.12 - 0.064 = 0.056 moles of ethanol at equilibrium. Hope this makes sense :)

Can someone explain for the second part of question 1, why 4 electrons produced??

[@TheGemRobin]

It's one of those simple half equations, so basically you do the EveryOne Hates Chemistry rule (EOHC). So first (E) make sure all the elements (apart from hydrogen and oxygen) are balanced; in this case the carbons already balanced so this is sorted. Second (O) balance your oxygens by adding H20 where it's needed; one oxygen on the left and 2 oxygens on the right, so you need to add one H2O on the left to balance it. Next (H) you need to balance the hydrogens by adding H+. 8 on the left and 4 on the right, so add 4H+ to the right side. And then finally (C) you sort the charges out. No charge on the left, but because you have 4 + on the right, you need to add 4 electrons to the right to cancel them. Hope this helps :)

[@fatimaalamien8786]

@@TheGemRobin hii this was so helpful , could u please explain why there are no charges on the left ?

[@gemmarobinson3838]

@@fatimaalamien8786 Just to balance out the charges - you've added 4 positive H ions so you need to cancel them out to make sure there's not an overall positive or negative charge on either side.

Sir which application are you used for this

[@daniel117100]

can some one explain question 20, i never remember learning about carbon dioxide in complex ions

[@jamalnajeeb751]

It's got a high charge:size ratio (3+) as he mentions. If you check out the other transition metal ions (M) with a charge of 3+ like Fe3+, Al3+ or Cr3+. When they react with carbonates (CO3^2-) they all form [M(H20)3(OH)3] a precipitate and CO2 Your best bet is juust to memorise this tbh Just tryna confuse us with the Ga for no reason :/

[@daniel117100]

wow nice one, my teacher completely ignored half of the complex ions topic

[@jamalnajeeb751]

Np :)

[@MissZeeXo]

for question 9, it wasnt that simple, you missed a step about the dm3 to dm3 conversion, thats where most people went wrong!

[@michaelc6294]

I’m just in a really shitty place right now

[@joewheeler3210]

few wrong answers , not sure about titre one as you read off the burette twice the calculation 2X0.15/titre value X100

[@bluetangerinebb]

I thought so as well but the question says "the uncertainty of the mean titre" not "the uncertainty of the burette". Since you only use the mean titre once his answer should be correct, at least that's what I believe.
