- 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.
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 ?
Absolute legend, I don't know why I still go to school.. migh aswell complete my studies with the help of RUclips and from talented people like you sir.
Ah. No substitute for school though. Hope your revision is going well.
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!
yaaa thts really trueeee🎉🎉🎉🎉🎉 thanku

No problem.
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 !!
I legit wish u were my Chemistry Teacher! Amazing video!.
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!
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!
Thank you sir.😊
I've been struggling with this for 7 months and you made me understand in 20 minutes!👏👍
You're very welcome!
Idk how much i can thank you, this video finally made me understand how to solve these type of questions keep it up!!
You're very welcome!
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! 👍
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!
To anyone who reads comments before deciding to watch a video... This doesn't have the nice computer animation and the dry erase marker is kind of hard to see and read but this is by far the best and easiest explanation I've found on how to solve these problems. And I have been doing some serious searching! Thanks for this, man!
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
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!!!!
Was so confused until watching the first 5 minutes of your video. Thank you !!!
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!!! :)
This is really the best tutorial I have found for Hess's Law THANKS
great video-best explanation on RUclips :D
Thanks very much. Pleased it helped you!
Watched this guy during my A-Levels now I’m back for my final year of degree….true goat
Thank god i found this video, i got a chemistry mock exam tomorrow and this was the part i was struggling on but now i fINALLY understand:) thank you sir
Was it helpful?
probably the only person that made this topic actually understandable, thank you!
This is a topic I had troubles with since semester 1 and I didn't solve it until today. Thanks a lot for this informative and easy to understand video !
Yes it is difficult! But important to know so I'm pleased you understand it now.
Allery Chemistry 😀
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
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!
Absolute legend, I have never understood this before, now 1 week before my exam I finally do, thank you so much!
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!!!!! 🍀🌹🍀
absolute life saver. i always hated this topic thanks to you its now my favourite
I really appreciate this video .It makes it make so much sense..You actually answered a lot of my questions
No problem!
omg where has this video been?? The best video of hess's Law
I finally understand this after I kept messing up the signs!! Thank you so much!!!!
Glad it helped!
Very well explained.thanks a million.God will always bless you.
From a mom who is teaching her children.
i just did my chemistry mock paper 1 and i just want to say a big thank you for your videos because even if i don't get high scores i actually didn't feel like i knew nothing on the paper and actually had a go at all the questions so thank you so much. hopefully ill be even more prepared for the actual exam in june
Is it really? Because i’m finding difficulty in chemistry and idk if i should watch his videos as a resource
I nearly jumped out of my skin when I saw this section. Thanks a ton for untangling the twisted Knots.
Yeh a tricky topic
i wish that i could have met u before sir, cuz this lesson is so easy for me now. thanks a lot sir....
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!
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.
Bless the existence of this video I'm literally cramming for my finals tmr😂
OMG thank u so much!!! u saved me!!!!!! Finally understood this concept!!!
No problem
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!!
The best explanation I have ever seen!!! Thank you so much!!!
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
My teacher confused me soo much but your video made it soo easy for me, thank you so much!
I wish you were my chemistry teacher instead 😂
My teacher couldn't even be bothered to teach me this properly, so it really means a lot :)
Mine too lol
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
ayo my guy came in clutch!!!!!
Sitting the Cambridge Chemistry Challenge tomorrow and this video has helped me so much! Thank You
thank you so much sir
was getting very anxious, this helped me loads!
Youre explanations are always straight-forward sir! Thank you.👍

Nik Danhawoor I felt that
Great video! The concept was taught really well, appreciate the help.
thank you so much!!! your video was the most straightforward and simple to understand!!! may allah reward you with goodness
Wonderful, short & concise tutorial, fab work 👏👏
I literally didn't understand this till i watched this video. thanks alot.
11:49 when working out standard enthalpy of combustion, why do we have to against the arrows and not the other direction, with the arrows? (why couldn't it be -86-2734 = -2820 rather than 86+2734 as you do in the video). Is either way correct? Also thank you so much, this video is really helpful!
I just wanted to say, THANK YOU FOR EXISTING.
Very useful video, clear explanation! Thank you
You are welcome!
You have made this so easy! I will definitely be using your videos for the next two years! Its great to find someone who is able to explain these topics so well, especially chemistry being so hard! Do you have any tips on getting your head around exam questions? Thank you!
you can tell that this man is a genuinely good guy really m8
Wonderful explanation, just all of it summarized so well!
Proper legend!!!
sir can u do harder questions
i struggled with this concept sm, but this video was super helpful, i think i've got it now, thank you so much! (:

this was amazing! thanks so much ur actually a legend u saved my life !!
actual legend! the only video that acc helped me w hess cycle is this video thank you :))))
Heh. Thanks very much! Yes Hess' cycles can be a bit strange at first but I hope I've explained it enough to see that they actually can be pretty useful! Work smarter not harder!
recommended your videos to my friends and subscribed very helpful for a level chemistry thanks
Excellent! You’re the man! 👊🏿
I appreciate that!
What do you do if a question gives both combustion and formation data
e.g:
Calculate the enthalpy of combustion of propanone, CH3COCH3(l), given the information below.
∆Hêc : H2(g) -286, C(s) -393 ∆Hêf : CH3COCH3(l) -217 kJ mol-1
Keep up the good work! This channel really helps !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Thank you sir, grateful for your help.
You're welcome 😊
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!
This man is a blessing for me😘😘❤
Thank You, this helped me a lot !!!
Thanks a lot this helped me soo much. May God bless you always.
No problem! Please share the vid. The more people that use it the better!
sure I will xo
Thanks a lot sir. Your videos are amazing!!
Glad you like them!
Thanks alot. Perfect explained
you're videos are amazing I love them defiantly recommend you to all my friends who are doing chemistry
Thanks very much!
thank you sm. You just saved my mocks grade :)
THIS WAS SO HELPFUL!!!
You're very welcome!
