Tyyyysmmmm sir 🤌🏻
Thank you so much for doing this video I didn't actually expect you to do it. Thanks. I was wondering if you could do ESQ for each topic for a level biology aqa on physicsandsmathtutor? If you could can you do topic 6 paper 2 ESQ for like control for blood glucose and homeostasis. Your probably busy but if you have time would appreciate alot. Your videos have helped me alot and I am actually starting to enjoy chemistry now. Thanks again
Thanks :)
Woww
Thanks a ton!!!❤❤
Pleas respond you know question 1.6 can U do e isomer so the cl is on left side of chromium and the other cl is on right side roof chromium intaed of having both cr top and bottom of Cr also when you say for E isomer it has to be oppositie I don't get like where is plane from
This is not like the c=c e z. When it is E isomer all the NH3 are in same plane around metal.ion but the other plane above and below contains Cl. The Z isomer would have at least one Cl above or below and one Cl in the horizontal plane you find the group/ element in both planes
A more technical way to look at it. Is if the all the ligands of the same type have 90 degree angle between them it is cis or Z if the ligands of same type have 180 bond angle between them it is E or trans. So in the example above where the cl is above and below metal.ion they are 180 degree apart so you get trans or e isomer.
How do we determine what q squared is and what p2 is as the alleles for the genotypes are codominant
@kamilahabubakari1088 Totally your choice. With codominant theres no recessive allele so you can assign one as P and one as q and the mIx of two alleles as 2pq it still works the same
@kamilahabubakari1088 So p2 Could be AA or BB and q2 is whatever the other is
Very good thanks
Thank you so much sir for doing this so promptly! These are very helpful
so helpful Thanks!!!
hello i am taking the harriss westminister sixth form entrance exam in 2 days do you have any advice
Its a difficult exam however best prep is too search online for available 6th form entrance exams on the internet and have a go. Mostly its GCSE level but they do ask AS level questions but they will give you the tools to answer the questions in the test. Prepare aswell as you can with the remainung time you have and do your best thats all you can do. If you give a good go and come up short then you can still be proud. Just makesure you try some past papers. Magdelan has some and its a highly rated school
This content is honestly amazing!!! Especially coz I spent hours trying to figure it out .Could you maybe do a video on the harder genetic crosses ?
Ocr or aqa
@ ocr !
Hi Sir. I know you dont really get many views so probably dont make much money from these videos but i just want to say that your videos really help and I am so thankful. I wish I had a teacher like you my teacher just explains content for chemistry but doenst really go through ESQ. I just found your yt channel a few days ago and the ESQ videos you have done on optical isomerism, aldehydes and ketones, carboxylic acids and derrivatives has helped me alot. We literally finished this topic in class today and have a end of topic test next week. For the first time I actually think i can get good marks in the test with the help of your videos. Im assuming you will upload a part 4 for carboxylic acid and derviates ESQ. Also will u do aromatic chemsitry ESQ after? Then i would he able to cover all ESQ for this topic thanks again
Hi I will do an exam pack for Aromatic Chemistry. Will release on weekend good shout for a video
1:26:55 why divide by 2 and not multiply by 2 for 2 atoms ?
Hi good question. Once we found how many moles of Edta reacted it was equal to the moles of AlH206 however we need the moles of Al2(So3)4 You need two Al(H20)6 (as.they only have 1 Al.atom) to make 1 Al2(So3)4 So if i have 1 mole of Al(H20)6 they can only make 0.5 mole of Al2(So3)4. Thats why we divide by 2. If you have 10 apples and it takes 2 apples to make an apple pie how many apple pies can you make from 10 apples. 10 /2 = 5 apple pies.
@@letsgettothemarks thanks! understand it now
Hello sir can you please do more edexcel A2 papers. Especially for a paper 3 even if its just one becuase they are hard and no one on youtube has dine a video on them
@@jefking2158 Hi ill do a paper 3 Edexcel chemistry or biology
@@letsgettothemarks A2 chem will be fab. Thank you
thanks sir
Thank you so much sir really helpful
Thank you very much. Appreciate you.
Hi sir, have you done a part 3 on this?
Not yet ive meant to do that for ages will do one tomorrow hopefully and upload
@@letsgettothemarks thank you so much sir
Hi sir, I am really sorry to bother you but when will the video be uploaded. I know you are probably very busy but I just needed the walkthrough before my test next week.
sooo helpful
Glad it helped!
thanks so much this really helps. This actually keeps me engaged unlike most other walkthroughs. THANKS AGAIN!!!
Hello anyone here?😅😅
I wish you were my teacher.
Hi where do U get these questions from also can U go over physicsandmathetutotur exam style questions a level chemistry for individual topics (revision section not pastpapers) pls
Hi I have done a few of these here is a link to one on carboxylic acids ruclips.net/video/gj65eO9XUpI/видео.html
@@letsgettothemarks Thank you so much I appreciate you doing these packs. I am struggling with like individual topics so I go over with physicsandmathtutor exam style questions. However sometimes I don't understand marchscheme id really appreciate if U can upload more of these videos thank you so much Ur literally a life saver thanks again
Thank you so much good explanation got my bio mock tomorrow
Thank you so much please don’t ever stop posting your videos !
Thanks boss
thank you🙏🙏
You're welcome 😊
What a good video wtf
thx rlly helpful!
Superbilous😂
appreciate the vid, any chance you could walk us through the 2023 A level chem paper 2? Thanks again u absolute legend :)
Yeah ill do 2023 p2 A level next week
u silly plonker of a teacher! love you very much xxx
Sir, you are a legend!
Hello Sir I am doing OCR A chemistry and we have that organic flow chart and I seem to be so confused or hard to remember about amines as well.. so many things to remember any tips pls?
@@Beautifulday1231r Hi ill make a video about organic synthesis and how to break it all down. My advise is to make a pack of about 20 revision cards. On one side you have the reaction eg halogenolakanes to alcohols and on the other side you have the reagents and conditions so in this case it would be reflux KOH nucleophilic sub etc
@ thank you Sir I seem to get it when its As but A2 just hits different!!!
thanks!
cheers boss
Thank you Sir.
You are most welcome
love the videos sir do you reckon you can just go through all of the AS aqa alevel biology indepth cause they’re alot of teachers who teach it but i learn it the most from you!!
@amoghvangapandu7284 will do looking to get through a couple of papers in the next few weeks
Thanks a lot sir!
Thank you so much
man like
can you do a walkthrough video of AQA A level Chemistry Paper 2 2023 please
@narmeen1192 Super will do

Here is a video on aldehydes and ketones have others on carboxylic acids
This was in my mock in end of yr 12
is this a question from edexcel
@@UltimateMemerSus No although it is applicable to the edexcel.syllabus this is one of the many topics that run through all exam.boards
underrated
Could you maybe do a video on buffer solutions or half titrations as I find them so confusing and found your explanations quite easy to understand
