I'm trying to get higher grades in my chemistry since I just started the GCSE courses and are becoming very difficult, but your simple explanantions are rrly helping me grasp the subject better. Tysm!
Again, another great video. Summarises everything and I’ve learnt 3/4 of my end of year exam that I am meant to sit tomorrow. Keep up with the amazing videos I am so glad to have found you!
Is another reason why a polymers boiling/melting point is higher than that oof simple molecular forces to do with the size of those Inter molecular forces? (as well as how many imf there are )
Hey Cognito You might have noticed me a lot in your comments now, it's a fact that I am using your videos to make my own notes, can you please exaggerate the types of additional and condensation polymers. If not a video, comment would work too. I like your video, great work.
Ok uhm anyone know what is the meaning of polymer using this video? 😊😀 Edit: nvm I found it. So now uhm does anyone know the properties of polymer using this video? Thank uuu :’)
Large molecules made up of smaller molecules called monomers Properties are that it has higher melting and boiling point cuz loads of intermolecular forces are needed to break them apart
Theres save my exams notes on it. If youre taking IGCSE it’s not a lengthy topic which requires video explanation but in general they are just a compound that’s presented in hydrated salts. If you want to test for water of crystallisation you can use cobalt chloride which turns from blue to pink if hydrated and copper sulphate which is white in anhydrous and light blue in hydrous.

Ah thanks, glad the content is helping 😊
not dat difficut if u keep u w da work n revise :D
@@yukislife572 it is if you don't have a good teacher like me so this channel really helps
Everyone is here because they have a test on polymers. I’m here because I have to teach it 😭.
The tables have turned
lmao😭
Again, another great video.

Keep up with the amazing videos I am so glad to have found you!
Thank you so much dvrina, glad you're enjoying the videos 😊
Same
Again u never let me down now I gonna pass am chem test thank u for ur amazing work
Thanks Amy, hope the test goes well 🤞
@@Cognitoedu it went perfectly I got only 90z and 80z thank u so much ur a life saver
POV: u have a test about polymers 🤦♂️💀
🤦♂️
🤦♂️
Pov: you have an exam that decides your future tmr
@@jerkhoff69 fr
well i have seminar 💀
Pls do more on the organic topic so helpful xx 🙏🏽

@@alinalilka8430 I think it was just a joke you should've kept it going 😭😭
bro tysm, i have my test overmorrow and i needed this sm
ur videos all ways show up when I search something up lul this is mazing
I had a class explaining this for an hour and I didn't understand anything about it.
Ur video made my brain open in 3 mins LOL... Tq
Could you extend theses videos to a level material. These videos are the best things to revise from ever
This channel is really useful thanks
Have you done one on polymer condensation and addition?
Not yet i'm afraid, we're working our way through the course in order, so that will come a bit later!
@@Cognitoedu awesome thanks!
@@Cognitoedu it’s here now!
Will you start uploading for A Levels sciences as well?
The animations help me learn better
Also, have you covered anything like the cracking crude oil or hydrocarbons
Why do we use a (Cl - Cl) “-“ notation for covalent bonds but not a notation for ionic bonds? Like instead of NaCl it’d be: (Na+-Cl)?
Thank you for such a great explanation
Nice and clear and slow. Thank you.
You are too underrated ❤
hey, can you tell me if if you would always put n even if you know the number of times it repeats. thanks
you put n only js to showcase h=how many times it can repeat

Would using square brackets instead of the curved ones be considered as a mistake on the igcse 0620 chem exam??
what software did you make this on?
when we watch your videos what else can we do to get them 9s in science
Do reaaaalllly well on your practicals and practise loads of past papers
Thankuuuu. This was really helpful
Thank you - this video has really helped me!!! :-)
revising for gcses thank you very much
OMG you guys are so good
Excellent well explained
I really luv the lessons from cognito
thankyooou radika 😊

I like your video, great work.
Just found that there are videos about them in playlist.
I am just fool never mind me
Bruh 💀
POV: you got moved into a set who just did this topic but it wasn't on the curriculum of your old class because they recently moved to combined
Don't we always use square brackets and not curved brackets?
no
ig we can use any of two.
@@silenceplzyeah2019 IDK, my teacher told me to ALWAYS use square brackets.
@@aaryanramani1699 maybe then you better see the mark scheme or simply listen to your teacher.
If you find out please let me know!!

Better than fuse school!
if it is a polypropene wouldn’t the diagram have a double bond since it’s an alkene
Watching this the night before my O Levels 🤪
Thanks for the great video
🥺i can see it all now...thank you✨🔥
💀💀
Thanks so much for this
I have exams in 2 hours and revising with this
Ty sir 🌟🧸
your content is so great thank you so much
Glad you're enjoying it Muhammad 👍
Thank you so much!!
POV: you're the one who will reports Polymers
My teacher told me to watch this
Same I was told to a few weeks ago only just looked at it
My also
@@sborkute3738 same lmao
same
@@averagegamer2724 hahaha-
is there an addition polymer video
That’ll be coming very soon, as currently we’re working our way through the course. Stay tuned! :)
POV: Miss Piggy is mad that Mrs Barnfield is telling me to watch science videos.
SHUSH. BRO MAYBE YOU WOULD GET SOME GIRLS IF YOU GOT RID OF THAT YEE YEE ASS HAIRCUT
MAYBE TANISHA WOULD CALL YOU BACK , IF SHE WASNT MESSING WITH THAT LAWYER OR BRAIN SURGEON SHE MESSIN WITH
lol he getting mad i aint from this school but u sound liek Londoners
@@ajaibbbbbb What? Ahghhhh (enters)
Tf happened here
POV your teacher sets tonnes of summer homework
every chemistry teacher : just watch this vid
I might do
Never gonna let me down, never gonna fail.
when you have a reporting about polymers
POV: the infamous Mrs Barnfield told you to watch
this
lol the infamous MS Haynes from my school told me to watch this
Tommorw is my polymer test
POV: you have a chemistry exam tomorrow at 10am
seems like a nice guy
is this paper 1 chemistry aqa
Pretty sure it's paper 2 as they're classed as organic, and paper 2 is all about organic chemistry
Thanks

Hello Mal :)
Maidens?
PLEASE CAN U MAKE A VIDEO ON WATER CRYSTALLISATION!!!!!!!!!!!!!!!!!!!!!

Oh It is 'GCSE' not 'IGCSE', I think my eyes gots some problems LOL
anybody else here because their teacher put this video?
do a beginners version
bro are you actally stupid this is a beginers version
@@yukislife572 💀
Thank you
Hi sir
