how can we calculate how much energy in unit of electrovolt [eV] each level (shell) and each sublevel (s, p, d, f) has?
Do you have a vid on Year 1 Organic Chem?
33:18 if the Ca is reduced, how is it a reducing agent itself? Shouldn't it be an oxidising agent? Please clarify
Do these notes align with the specification? super helpful btw, thank you! :)
i don't take chemistry but i am now confident i will pass
Can you solve this question? Who is creat the word chemistry
Thank you so much for making this video
Supposed to be 2 bonding and 2 lone pairs for bent or non linear
Can you upload link dor the slides please
hey, at 7:34 you should measure pressure in pascals not kilopascals. amazing video though!!
thank you for the video!!! one question , the energy of the 4s energy level is not less than the energy of 3p it is more... this is how it goes 1s,2s,2p,3s,sp,4s,3d
“Metals always have a positive charge” Gold with the electronegativity of carbon: am I a joke to you?
can i use what i learned from this video for Organic Chemistry ?
easy stuff
Great video. I do make a levels video too. Hope you don’t mind if I share the link here. Thank you. ULTIMATE GUIDE FOR BALANCING CHEMICAL EQUATION USING OXIDATION NUMBER | CAEI CAMBRIDGE CHEMISTRY | ua-cam.com/video/qsG7S19MtJE/v-deo.html
999 lol
Great work! You explain things so clearly! I shared your video with classmates! You should have more subscribers!
couple of mistakes in this video but otherwise really helpful
26:56 ice is less dense than liquid water*
This is more like gen chem than college level inorganic for those looking to not waste their time…
Amazed you saw OCR A-Level Year 1, a whole english exam board with a spec called inorganic chem, and thought ah yea sure mate thisll be perfect for my college course. Fam this is for us stupid fuckers doing the eponymous OCR A-Level 🤧
here the night before the exam. I really hope this works lol
did it go well?
The units for pressure in the ideal gas equation is Pa not kPA!
Pressure is in pa not kpa:)
Thank you so much! This helped me to consolidate all my knowledge of the Year 1 topics in one go and in a short amount of time. I'm was super stressed out because my end of year's start next week but this run through thorough all the topics has honestly really helped me. Thank youuuu :)
I've never been good with Chemistry, but this just helped me pass a difficult paper. Thank you. Keep up the great work.
I procrastinate for 2 weeks, then revise half the entire course in 30 mins(x2 speed) 💀

18:55 How does Ionic Bonding form COVALENT lattices??
😂
Great video 👍 lots of fun to watch 👍
Collision theory
collision theory is basically: A reaction will not take place between two particles unless: - they collide in the right direction and orientation - they collide with an energy greater than the activation energy

can u make this for the year 2 content too ? it’ll be rlly useful for students having summer exams in 2022 thanks for all the support & ur hard work ❤️
Interesting that this is called "Inorganic Chemistry" In the US we refer to this as General Chemistry, or Gen Chem for short
2 x speed gang ✌
Damn, a whole year in _twenty-five_ minutes
It's the only way🙌
whole vid in 25 min
u......are........AMAZING!!! can u pls do one of year 2 as well?

no bc ur acc a lifesaver tysmsmsmssmm
This was so fun watching, thank you so much!

At 3:44, dichromate is missing the "di" in the table. Thank you so much for this video
Huh?
Doesn’t the atomic radius INCREASE down a group? Because more electron shells are being added 29:50
Yes
Yeah I think she got that wrong I searched it up aswell to make sure
@@omas1154 he*
Thank you for making this video, can you please create one on the whole of year 2 and organic chemistry please :)
🗿
Thank You🙏
Tp be honset This helps alot Thanks alot...upload more like this please...
ice is not denser than water
27:00 "Ice is denser than liquid water". I don't think so, Sister.
ice IS denser
@@pogu2224 why does it float on water then? Ice has the highest density at around 4 °C in liquid state.
Ice is less dence than liquid h2o
Thank you.
nice videos. i create videos for a level chemistry CIE. maybe my channel will also help any a level chemistry students here. thank you. @UCUlaVAyazVt18b2f3QOswIw
