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!

Ah thanks, glad the content is helping 😊

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!

[@lasa18]

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)?

Better than fuse school!

no

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 )

[@moto2663]

I have exams in 2 hours and revising with this

[@iman2256]

Would using square brackets instead of the curved ones be considered as a mistake on the igcse 0620 chem exam??

[@Sarah-w8m2p]

Thanks for the great video

[@WEEBWHOSELLSWEED]

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.

if it is a polypropene wouldn’t the diagram have a double bond since it’s an alkene

is there an addition polymer video

That’ll be coming very soon, as currently we’re working our way through the course. Stay tuned! :)

[@apocalypse999]

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

PLEASE CAN U MAKE A VIDEO ON WATER CRYSTALLISATION!!!!!!!!!!!!!!!!!!!!!

[@didyouforgetalready]

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.
