Failed?

this is actually incredible; i’m learning all 3 sciences’ content through your videos and, for once, i genuinely understand topics i used to find difficult! i feel confident now- my gcse exams are next month, i can’t thank you enough.
How did u do
@@Lamplovr i got an 8 in chem, i was so shocked because i normally got 6s
@@ashleyyy955 proud of u bro but also give me tips 🙁🙁
@@Lamplovr tbh, i was really lazy during the year leading to my exams, but binge watching cognito and freesciencelessons a few months before mocks/the final exams really really helped
i also found that making a good revision schedule helped loads, if you're motivated enough then it's actually really easy to follow and include good break times :)
there was also a channel (ExamQA) who did lives hours before different exams for that specific exam's revision, i'm not sure if they'll be doing it again but there might be other channels if you look
good luck with your exams!!!
@@ashleyyy955 I appreciate you taking ur time typing that IM GRATEFUL THANK YOU🙏🙏🙏 you’re such a real one!! ☝️
youre a life saver man i slept the whole day even though I planned to nap and I have a chem test in 4 hours!!! your videos are helping me out so much really I've been failing chem for like 2 years now cuz my teacher sucks lol but your videos have saved my ass on test days. thank you so much!
Same here. My teacher didn't even know what a mark scheme was she would spend three hours explaining one paragraph, and no one would understand anything
Imma pass my GCSEs for you
my teacher is setting us these videos in almost every lesson! i love these videos as they are so insightful and easy to understand. you really do it well
How is it that you made such a difficult topic a piece of cake?! Thank you so so much for the ease
Glad you're enjoying the videos!! 😊
omg I love you guys soo much u literally helped me for my mock exams I only have 7 days left you guys are like lifesavers I recommended this to my friends
How did your mock go?
@@samueldcosta6893 we got sent home for lock down in December we are not going to school till March the 8th it's kinda sad after all that preparation
@@joanmathew1354 anyway you would have failed right?
you would have failed right?
@@motivateyourself8506 I see why ur name is "motivated urself" lmao
thanks so much, due to having covid, i have had to learn almost the entirety of the organic chemistry myself. so thanks for your aid in these mocks. mine's tomorrow- looking for a 9
hope it went well :)
@@Bear-xd3mx it went fantastically today
@@zincbakwarrior9844 i'm so glad !!!! here's to a 9 :D
how was the result?
@@alinaashfaq1742 i got an 8 :( i fucked all of my gcses (apart from an 8 in citizenship) very displeased
If you’d like to practise what's covered in this video, check out the lesson on the Cognito platform - cognitoedu.org/coursesubtopic/c2-gcse-aqa-h-t_7.14. The platform’s totally free, and has been built to make learning and revision as easy as possible. The main features are:
- Lessons organised by topic, only the lessons relevant to your specific exam board and tier are shown.
- Automatic progress tracking. Progress bars tell you what you’re doing well at, and what you need to spend some time on.
- Practise quizzes so you can test your knowledge. You can quiz yourself on any combination of topics you like.
- A huge number of fully-hinted questions that take you step-by-step through some of the trickiest calculations & concepts.
- A comprehensive bank of past exam papers, organised both by year, and also by topic.

where is the maths????????????
@@thanansayanbalachandran6081 here now mate
Hello, I really love your videos. Can you make a video on isomers and how to draw them?
yes................same here
thanks a lot man
I like your explanations
thank you so much i have my exam in 1 and a half hour
Hope it went well Rhidhan 🤞
@@Cognitoedu yes thank you soooooo much
If i got a full mark by these 3 mins
I will thank for the rest of my life bro
I hope you make a video on how to make alcohols by fermentation
Can I know what apps you use for edit this video?
thanx cognito. its so helpful
I really appreciate you ,for de video
nice
Lovely video
how to remember the symbols for butanol etc
There maybe a typo in the description; 'carbonates' should be replaced with 'alcohols' for how carboxylic acids are made
at 1:16 should it be called a reversible reaction arrow? Equilibrium is slightly different. I may be wrong tho :)
i think its because only a reversible reaction has equillibriam
Thanks
Hello Mr Davies
year 11 triple
Cognito literally saves lives.
May God bless you
Miss Musoke was almost here
i just learned more in three minutes than i have in 4 weeks lmao thank you
I didn't get how at first that in methane hiw H came before COOH anf CH3 before COOH
Video #69? Nice.
Video no 69
Nice
What about palmitic acid
Good morning Boys
Can someone explain the reaction at 2:40? You have 4 carbons on both sides but you have 8 hydrogens on the acid compared to the 10 on butanol. What happened to the others? I know we added an oxygen due to the oxidising agent but why lose 2 hydrogens?
Oxygen is diatomic, which means it has 2 atoms, One of the atoms reacts with the alcohol to form a carboxylic acid. The other atom reacts with the hydrogen to form -OH.
The second hydrogen is in the -COO(H) itself
Good videos but good i dont have to watch them anymore as GCSE’s are cancelled
They are cancelled for may and june but not all together.
xyz23 have you seen the education secretary giving an interview
i think the entire world knows by now that gcse's have been cancelled, you don't have to tell the man such an obvious fact, he is not living under a rock.
@@purplebea501 not everybody has 'GCSE' buckaroo
@@lazybones1342 but no one lives under a rock
2:42 i dont understand why there are only 8 hydrogen atoms in butanoic acid... arent there supposed to be 9 hydrogen atoms because butanol had 9???
I'm not sure either, maybe it was just a mistake. But I think that it's the way the oxidising agent makes it lose some hydrogens.
The oxidising agent replaces one Hydrogen atom and replaces it with oxygen....as u can see in the reaction...the product has a O2 with a double bond
Formula ??
For example in Ethanoic acid, the formula is CH3OOH, why don't you just put the hydrogen on the end with the CH3 in the start and write CH4OO instead?
It’s written that way to help show how the atoms are actually linked together. Not something you have to worry about at the moment, but as you learn more about chemistry, it becomes important :)
@@Cognitoedu Alright thanks!
I know Cognito has basically said this already, and I know I'm 2 years late but it's just so that you can see the functional group, and for carboxylic acids, that would be -COOH
A
wow
Well barely anyone will watch now, exams are cancelled
bhallage nai bhai
Sorry bro, gcses over
sht videos
bro is mad
@@Boosher_ bro boossher whats up with u
@@f9iteeditz I'm confused why you do this
@@Boosher_ becasue i don't sometimes understand his videos
@@f9iteeditz sounds like a you problem ngl😊
nice
