Organic Chemistry Lesson 7 - Carboxylic Acids (Triple Only)
Переглядів 3054 роки тому
In this lesson we will explore the structure of carboxylic acids and how they're prepared via oxidation of alcohols. We will then explore the properties of carboxylic acids as weak acids and their reactions with carbonates.
Organic Chemistry Lesson 6 - Alcohols (Triple Only)
Переглядів 4654 роки тому
In this video we will explore the structure, properties and production of alcohols and evaluate the environmental and economic aspects of their use and production.
Enthalpy changes of solution and hydration
Переглядів 8834 роки тому
In this video, we will expand our understanding of Born-Haber cycles by applying it to enthalpy changes of solution and hydration in order to calculate an unknown.

In this video we will look at how to construct Born-Haber cycles and the associated calculations.
Lesson 4 Combustion of Fuels
Переглядів 9384 роки тому
In this video we will explore how the hydrocarbons found in crude oil are combusted as fuels. We will examine complete vs. incomplete combustion, learn how to construct and balance combustion equations, and look at some of the issues associated with the products of combustion and how they can be identified.
Displacement Reactions - Lesson 3 - Chemical Changes
Переглядів 4044 роки тому
In this video we will explore displacement reactions as well as how to determine the formula of compounds in order to write balanced symbol equations.
Crude Oil Lesson 3 - Cracking
Переглядів 3,1 тис.4 роки тому
In this video we will explore how the long chain hydrocarbons found in crude oil undergo cracking to produced shorter, more useful chains.

👏👏
Can you do an experiment for Magnesium ion with titan yellow and NaOH in excess pls😢😢
merci beaucoup !
why does excess sodium hydroxide redissolve the white precipitate in aluminum?
Awesome!
Thank you
Thanks for this video ❤❤❤
0:00 to 4:09 same observation of Zn+2 as aluminium
I was heating melted electronic scraps in hcl. Poured in NaOH(aq) and got a black precipitate. I have no idea what it could be. I thought it was iron but it wasn't green or red. I guess I'm going to have to dry it and do a flame test to find out.
Best video I've seen on this topic .However, I would have just included zinc, it also forms a white ppt in NaOH ! , its soluble in excess giving colorless solution.
THANK YOU SO SO MUCH
It's not only Al+ that dissolve in excess NaOH
Icse class 10 gems English school ❤
Wow Thanxs I can understand now❤
YOU HAVE THE VOICE OF COGNITO
Nah not really
Legendary channel
it is very useful. thank you so much.
Perfect sir exactly what my teacher explained in class
As an American, I use Fahrenheit and referencing them in your videos would be so helpful. Thank you.
Bro, as have somebody who’s trying to get into the oil and gas industry myself. Can I just say, that this is the best channel I found so far. You’re a God Sent 🙌
Really helpful videos ! Are you planning on doing any more A level ones please ?
Great video
Certiiiiii
very clear explanation, thank you!
What about the fact that hot air rises because of gravity? How does the bottom of the column stay hotter than the top? I'd really appreciate your help!
When forming the ethylnitrile (at 6 mins), why does the N become positive? I don't understand the explanation of just saying it makes more bonds.
Bless you son. Excellent. Excellent. Excellent 🌟🌟🌟🌟🌟
Thinks! great videos, so clear.
Thinks a lot!
finally understood this cheers
Will the ocean “run out” of plankton?
Indeed as they may extinct.
Likely not, unless as Jass suggests they go extinct. If your argument is "surely crude oil is technically renewable if plankton can be replaced" then you're I suppose correct. However the finite nature of crude oil regards the disproportionate rates of consumption vs production.
Are these all the mechanisms you need to know for aromatic chemistry
i can see why my chem teacher told me to watch this. Keep up the good work!
awesome content
Thank you soooooo much!
Nice, I like your method of explaining. Good Job
Keep teaching
Hi sir
Thanks you sir
thank you so much sir - this is the best video by far on UA-cam for born- haber cycles. I think i might actually stand a chance in my mocks now! Cheers Sir!
Absolutely great video, very detailed and well explained
Thank you so much!
HAHA this explanation is much better than bilal Hameed LOL
I studied 15 handouts in my class but your short video has cleared all my Doubts. Thank you
I haven’t understood this better with any other video other than yours. The detailed explanations are great! Thanks sir
Well explained.👍👍
thank you
loved the fact there wasn't so much clutter on screen, quality of audio and everything else is really good
Hi i love your explanations can you please make more videos for year 2 content especially organic as watching your videos makes me feel like i get it way better than being taught by my teachers
Thanks ..really helpful video
thank you very much, sir
Thank you, very useful lectures
