8.3 Bond Enthalpy | Calculating Delta H | General Chemistry

[@kkrieski]

Seriously, these videos are saving my life! Thank you so so much for the time you've spent helping us all learn chemistry! 😊🙌🏻

[@ChadsPrep]

You're welcome and Thank You!

Powerful Video! Three different ways to calculate enthalpy !

[@ChadsPrep]

Glad you found it helpful, Jon - Happy Studying!

[@SuzannesTutoring]

AHA! This is what I was looking for. I was confusing enthalpies of formations with average bond enthalpies. Thank you very much! Also looking forward to checking out all your organic chemistry vids on your website. In the orgo class I'm taking, we're mostly left to teach ourselves, so these will be immensely helpful :-)

[@ChadsPrep]

Great to hear that you're finding the videos helpful Suzanne :)

[@Ahmadthegoat762]

Thank you soo much for helping us learn these specific way of learning enthalpy these past videos😊

[@ChadsPrep]

You're very welcome!

[@devikanair44]

thank you for clarifying when to use bonds broken - bonds formed vs products - reactants! Hoping just the table given of Delta hf or Bond enthalpy value will be clear!

[@ChadsPrep]

It will be clear. The difficulty comes when students don't realize that they should be looking for which of the two are actually given...big source of confusion but I think you got it!

Hi in 2H2+O2---->2H2O Is the delta bond enthalpy different than the delta heat of formation?

[@FrontierThesisYU]

Amazing lesson. Thank you. Do you have videos for Introductory Biology and/or Biochemistry anywhere, please? Do you plan on making them?

[@ChadsPrep]

I don't currently have one on youtube but I have a free biochemistry playlist here: www.chadsprep.com/chads-elementary-biochemistry-videos/

Thankyou for more understanding

[@ChadsPrep]

You're welcome

Since H bonds are weaker than covalent bonds Shouldnt the enthslpy between O-H be noticeably different from O=O?

life saver !!!!

[@ChadsPrep]

Excellent!

[@n2flight125]

You are a lifesaver! Thank you so much! P.S. Love the shirt :-)

You're welcome and Thank you!

Thank you so match ❤❤

[@ChadsPrep]

You are very welcome.

Sir is enthalpy of formation always exothermic because it is the enthalpy of formation reaction

[@ChadsPrep]

Most enthalpy of formation will be negative (exothermic) with a few exceptions, for example NO

[@luke_MacLaughlin]

Can confirm that students do sometimes forget they have learned 3 distinct ways to calculate Delta H 🤣

[@ChadsPrep]

Yes Indeed!!!
