How can we calculate the enthalpy change of a reaction without doing it? There are two easy ways! This is how we can make sure a reaction won’t explode in our faces!

Sorry guys, there's an error! At 1:26, the second reaction with carbon dioxide as a reactant should have a change in enthalpy of positive 566 kJ. That changes the answer from what I've shown so please make a note of it. Luckily this error doesn't change the algorithm used, so apart from that you can still apply this concept to any set of reactions as shown here!
هذا هيس ابو المعادلات 🤝
Does heat a formation talk about the required energy to make that form out of regular disassociated ions?
What's the difference between potential energy and enthalpy?
This law is nostalgic
Good
so easily explained thank u
The wrong value for reaction enthalpy makes this video super confusing. Just update a new one without errors if you're about people learning stuff
Thanks papa dave
How do I know the value of the heat of formation of each compound?
You will live long
Hi Professor Dave! Quick question: I find the H*f of water to be around -285 kJ/mol in every resource I see. Which source did you use to get -241.8 kJ/mol? Your videos have helped me study so much, thank you!
Sir you are great😊Now I understood Hess's law well..thnk u soo much sir🌝
Since H2O is liquid at STP, why did you use the number for it in a gas state?
merci 😭😭😭😭
thank you so much professor!! this helped me so much since tmr is my chem final exam,
good explanation
That was helpful thank you 🤍
HOW IS O2 EQUAL TO 2O2
Thank you so much for your help
You should have said the H2O was vapour and not water as I used the wrong enthalpy for it. No matter
What is the difference between this and standard enthalpy change?
You are like chemistry Jesus you save us all!
Thank you chemistry Jesus.
Excellent!
THANK YOU SIR YOU CLEAR MY DOUBT
You explain everything so so well. Appreciate the help
Thank you Chemistry Jesus
there needs to be state symbols for that reaction
I hate videos with errors, tch!
I'm just a little confused when we use
Kj/mol
Kj
or when we talk about
Standard enthalpy of formation
Enthalpy change
enthalpy change of reaction
Is there a video talking about this more? and the differences if anyone knows
Apa cuma saya disini orang indonesia
Thank you so much
Can u explain standard enthalpy of formation and combustion. I'm a jee aspirant, please explain this it will be very useful
I'm here after searching for Rudolf Hess
Why is your theme song so damn catchy ffs
Yo yo
Hello, is there a way to calculate the heats of formation?
I have a science project where I need the heats of formation for diesel and biodiesel, and its heat of formation is not online.
