- The dreaded Hess's cycle I hear you cry! Hopefully this video will put those Hess's demons to rest. Take a look to find out how you use a Hess's cycle and how to draw them correctly in order to work out enthalpy of reaction, combustion and formation.
Absolute legend, I don't know why I still go to school.. migh aswell complete my studies with the help of UA-cam and from talented people like you sir.
Ah. No substitute for school though. Hope your revision is going well.
watch these videos carefully kids.. I got an A grade in chem following this channel ;)
Grade A comment too! Thanks for that!
kids? u fucking muppet u probably got a U grade
same here
Will do
Can I use these videos for Cambridge syllabus too ?
I’ve been struggling at this particular chapter for ages AND YOU FIXED IT ALL WITHIN JUST 20 MINUTES OF PURE MASTERCLASS. may god bless you, thanks for being such a blessing. Means a lot istg
You're welcome!
you are an amazing person!
never understood this concept so well until now...THANKS A TON 👍👍👍
No problem.
I legit wish u were my Chemistry Teacher! Amazing video!.
Sir, I am a Sri Lankan doing cambridge A levels. For like 1 and a half year I had no clue of what the hess's law is, i asked many teachers but i didnt still get it, just watched this video now and now hess's law is the most easiest lesson for me !! THANK YOU SOO MUCHH SIR !!! I REALLY WISH IF I COULD MEET YOU !! YOU ARE AMAZIMG !! KEEP DOING SUCH VIDEOS SIR !!
This is honestly the most well-done explanation for Hess's Cycles I could find, absolutely outstanding! Wish I had discovered your channel sooner, love the content! Keep up the great work mate!
This has been stumping me for the past 2 years, thank you so much. It is a lot clearer now!
Yes Hess's law is the thorn in the side for A level chemists up an down the country! Pleased you now understand it. An exam favourite!
You are a genius! I've spent the whole day watching your videos in preparation for my AS exam tomorrow! These have really helped me to understand key topics that I didn't get before! If I do well in chem for my predicted grades, I'll thank you!!
Hope your exam went well! Please the vids have helped you too, makes it all worth while!
the best video out there for understanding Hess Cycles. I struggled so much trying to learn these but this video made them so simple and understandable, just what i needed as my mocks are in a couple weeks!!! :)
great video-best explanation on UA-cam :D
Thanks very much. Pleased it helped you!
I hadn't understood this for a while but after watching this video, everything has been cleared up! Thank you so much!!
You're welcome!
This is really the best tutorial I have found for Hess's Law THANKS
thank you! I missed my last chemistry lesson which was on this, and I was totally clueless as to what was going on since I hadn't learnt it. I watched so many videos but none helped apart from this one! I have had to try to teach it to myself, so thank you so much for this, i really cannot explain how much its helped me, and its not the first time that your videos have just made me get something so easily. THANK YOU!!!!
Amazing video, you actually give us the time to follow you as you go through everything quite slowly, which is quite rare in science videos. Even better for foreign students like myself. Thank you! Really really loved it
Youre explanations are always straight-forward sir! Thank you.👍
Please never stop making these amazing videos! you are a great help
Thank you sir.😊
I've been struggling with this for 7 months and you made me understand in 20 minutes!👏👍
You're very welcome!
The best explanation I have ever seen!!! Thank you so much!!!
Absolute legend, I have never understood this before, now 1 week before my exam I finally do, thank you so much!
thank you so much for the video, i didn't understand Hess's Law until i watched this.And i am glad to say that it helped me understand it so much better.
Was so confused until watching the first 5 minutes of your video. Thank you !!!
im in love with the way you teach you are a great person!
You are the best teacher ever!!! You just cleared all the doubts I had in this topic!!! I can't thank u enough!!! Lots of love from Bangladesh!!!!! 🍀🌹🍀

No problem!
I'd feel terrible if I didn't thank you for this amazing video- thank you so so much for making this topic so easy to understand, I was really struggling with this as the textbook explanation was pretty confusing. Thanks again!
Its the best tutorial on Hess's Law! Yesterday I taught my student using this approach and they told me it really made things clearer!! Thanks! I would apreciate if you could do Enthalpy level diagrams for AS AQA in the same way, would be amazing!
Literally just saved my life for my chem test tomorrow - thank you!!
I like the way you explain the on the board....traditional and best way to learn due to interactions and what I like...Thanks sir..You saved my grade..so useful I used to watch this sir everyday after lessons and got me A in As level chemistry...Thanks and keep it up
This was really helpful for me Thank you SO MUCH!!!!
Very well explained.thanks a million.God will always bless you.
From a mom who is teaching her children.
Just had a go at the calculations before you did them and I got them both right! Absolutely buzzing now that I understand it more.. HESS CYCLES ARE NO LONGER SCARY!
It has taken me forever and a half to understand the cycle calculations! Made it make sense - THANKYOU
You're very welcome. Pleased it helped! 👍
thank you so so much! you are saving my chemistry as grade. i almost cried in lesson because i was so confused and you explained in 20 mins what my teacher couldn't explain in 2 hours
You're very welcome!
omg where has this video been?? The best video of hess's Law
Cheers bro this was really helpful for my revision if I do well in my test it’s because of you

I'm currently in year 12 preparing for my end of year exams which start on june 20th, these videos have helped me understand the energetics topic that I have struggled with, thank you so much, im aiming for at least an ABB in chemistry, biology and business studies
Good luck
@@AlleryChemistry sir do you have any main websites that teachers get exam questions/inspiration from?
Business studies instead of maths ?
@@arlobryant4231 a lot of teachers get questions from physics and maths tutor so I recommend looking at that
Thank you sir, grateful for your help.
You're welcome 😊
Thank you very much!
Life saver,thanks genuinely appreciate it 👍
You're welcome!
that was a real good video, you explain really well
This man is a blessing for me😘😘❤
wowowow you just saved me for my test tomorrow, my teacher does not know how to teach, i got it straight away with you. :D
Never mind a mourinho masterclass against Chelsea yesterday this is an allery chemistry masterclass in Hess's cycles 😂👌
Heh! Thanks, what a result it was for the red devils! My local side Newcastle will be challenging you lot next season!
Allery Chemistry Ipswich were a bit of a struggle never mind united 😉😂
Yes. Newcastle supporters get used to inconsistency. They are a nightmare for the bookies. I have my real club - Morpeth Town FC - great football, only lost 1 game at home all season and won the rest! FA Vase holders too!! Nice to see a team that delivers time and time again!
THank you sir.. really appreciate the video.
thank you sm. You just saved my mocks grade :)
I nearly jumped out of my skin when I saw this section. Thanks a ton for untangling the twisted Knots.
Yeh a tricky topic
Cheers needed to learn this as got a U in my year 12 mocks really helped me
Nik Danhawoor I felt that
Thanks a lot sir. Your videos are amazing!!
Glad you like them!
excellent explanation
Sitting the Cambridge Chemistry Challenge tomorrow and this video has helped me so much! Thank You
Fantastic stuff
Simply superb
Does anyone know how you work out Hess' Law of combustion/formation if the values given from an equation?
Love this video thanks!
.
.
Question - at the end of the Combustion cycle explanation you flip the question around to see how you would calculate the enthalpy of combustion of glucose. the answer you get is +2820.. does one simply just change the sign because it is an exothermic reaction overall?
Thank you so much
Great work!!
Thanks vey much! Please share the vid, the more people that see it the better!
Excellent! You’re the man! 👊🏿
I appreciate that!
Thank u so much u are an absolute life saviour
I appreciate this so much
You're very welcome!
