THANK YOU! My school decided to basically give us regular level exams (unseen questions AND marked by the board) but a month earlier, so this is great for quick revision!

[@cerenkoc.c]

I’m very grateful for your videos, especially in this pandemic 👍👍 You explain things so clearly that whoever has you as a teacher must feel lucky, thank youu :)

[@vm8886]

Your videos helped me so much this year thank you!

[@AlleryChemistry]

You are so welcome!

[@B1ast03]

thank you so much clearing my doubts and questions very impressive work

[@AlleryChemistry]

You are most welcome

[@igcsewithsadaf]

Great lesson 👍

[@Ollie28]

saves the day once again

[@zahraareeves2408]

Thank you so much! This is very helpful

[@AlleryChemistry]

You're very welcome!

[@rabiarafique9821]

Awesome description

[@AlleryChemistry]

Thanks!

[@himandiabeysundera]

hi thank you so much you helped me very much. but dont you have a revision for edexcel organic chemistry Arenes and organic nitrogen lessons?

[@daisylawrence7447]

22:25 how do we know concentration of CH3COOC2H5 = H2O? P.S thanks for such helpful explanations.

[@TheEverythingPill]

its a weak acid so we assume

[@abdullaasad4992]

does this apply for edexcel chemistry international alevels?

[@summa1749]

as usual so straight forward and easy to understand thank you! i wanted to ask about paper 3 for edexcel, do i need to revise the core practicals or are they not included? i'm a bit lost as im self teaching. cheers :)

[@amirah3791]

hi, i'm self-teaching too and i'm confused about p3 as well - please let me know if you find out!

[@abdullaasad4992]

Does this apply for edexcel IAL?

[@abdullaasad4992]

22:25 how do we know they are the same

[@salemabrahaley2774]

the reaction produces 1 mole of each, and the volume is the same for both as they're in the same container. so its the same concentration

[@stardreamix786]

same i am confused i have exam tomorrow 😭

[@CatherineBusola]

@30:32 why is it not 3 moles of SO2Cl2 as you only used 1 mole in your ICE table, but in the previous example you used 2 moles 18:02

[@ardchayasatheskaran5580]

Amazing, thank you

[@AlleryChemistry]

Glad you liked it!

[@wombatcom]

Sir, at 23:00, how do you know the two products have the same concentration? Thank you

[@ItsTheEddemundos]

Looking at the reaction equation the products are formed in a 1:1 ratio - so they are going to be produced in equal amounts and will have the same concentration

[@RahimaO]

@@ItsTheEddemundos they will have the same number of moles bc of 1:1 ratio sure but how do you know the conc in both are the same

[@cybro8925]

21:07 how can any of those species be put in the Kc expression if they're all liquids?

[@ItsTheEddemundos]

they're all in the same state (i.e. liquid) so it's a homogeneous reaction - omitting pure liquids/solids only applies to heterogeneous reactions

Chriss you are gr8

at 23:00, how do you know the two products have the same concentration? Thank you

[@JackM-un8co]

From the equation, they are in equal moles (1:1) and the total volume is the same, then if concentration= moles/volume and they have the same moles, concentration will be the same.

[@juliabenvs827]

yeah but then why dont the reactants - ethanoic acid and ethanol - have the same concentration as well?? shouldnt they be the same?

[@daisylawrence7447]

@@JackM-un8co Hi, how do you know total volume is the same?

[@vaishnavk5833]

when are the other videos going to be made public

[@AlleryChemistry]

Everyday at 12 noon. 👍

[@terminardo]

[@manlapyt3679]

how do you know that the initial of 2NO2 is 0.72?

[@salemabrahaley2774]

mass was given, mass/mr=moles

[@fizzaabbas3756]

18:00 wouldn’t it be 0.72- - 0.430 = 1.15

[@hotblooder6126]

I wanna ask is this a levels or international a level

[@AlleryChemistry]

They are just for the UK spec 👍

​@AlleryChemistry can IAL students still watch it

most of this is just recap of year 1
