Are there liquid fuels with higher specific energy than hydrocarbons?
Different alkanes always end in "ane". E.g, But"ane" and Prop"ane".
If your struggling to remember the first 4 alkanes remember this saying: monkeys eat peanut butter. Methane, ethane, propane and butane
i yo get back to work!!!
Anyone else here whilst waiting to get on a plane ?
thx soooo much
You’re very welcome! Thanks for the support and taking the time to leave us a comment 🙌
Cognito, what is your training in chemistry? Do you have a Chemistry degree? PhD?
lol
Hi, are you gonna make any videos on Reactions of alkenes and alcohols? Those are the next two topics after this but not in your playlist
Hi, they're at the end of the playlist i think because they're triple science so we did them later :)
@@Cognitoedu Ah thank u
@@Cognitoedu Hello again, have you guys got a video on alloys?
4.10.3.2 in the spec

Uhhhh Im gonna fail my GCSE 😫
No you are not. Believe in yourself.
You can do this.
We've got quite a bit of time so we're good. If you're in triple science which you probably are then you definitely have the mental capability to pass as long as you revise what you don't understand
I recently move to Saudi Arabia 🇸🇦 and I lived in America almost all my life and I couldn’t understand the teacher I watch videos in Arabic didn’t understand then I was like why do I not watch videos in English so I popped up into your video and thank God I watched it now I understand what my teacher is yapping about 😂😂😂
You literally saved my life... not just in Chem, but Physics and Maths as well... I am very new to the GCSE syllabus and I am very late to join school because of migrating to back to my country..... I am behind everyone else in my class but thanks to your videos now I have started to catch up with them..... I can't thank you enough! May God Bless you.....
Ah that’s a tough ride - good luck with all your work
