8.1b Born Haber Cycle | General Chemistry

[@LeonardoCastro-ge2dl]

Hello, professor. I just wanted to briefly thank you for these videos. I started university a month ago, and I had a terrible high school base for everything, and honestly I thought I was lost and that maybe I got the wrong choice. But your classes simply saved me in a way no other professor was ever able to put Chemistry in my head. My first test is tomorrow, and I still have some videos to go through, but I already expect better results than I did a week ago. Thank you very much for making this available. Big hugs x

Thank you for letting me know how the channel is helping you. I hope you do well on your test tomorrow. Best and Happy Studying!

Never stop uploading such an amazing informative videos

Glad you enjoy them, Belay!

Seriously i didn't found such sort of best teacher even in my college and in u tube also

[@ChadsPrep]

Glad you found us!

Will we always have 1/2 in these questions on one side of the equation? just curious?

[@Nonameerwe]

why do you put 1/2 in front of Cl, do you do it for all anions?

[@jawatu6326]

Because you balance it so it matches NaCl

[@AvinAhmadiiii]

Sir you just saved me , thank you!!!

[@ChadsPrep]

You're welcome

What exactly is the energy for betwen 1/2 Cl2 to Cl? Becauee they are both in gaseous state already

[@JohnDuong-le1jl]

I think it's the bond dissociation energy

[@AgborSamuelEyoung-gq6ot]

I love your teaching sir and I wish to learn more

[@ChadsPrep]

Thank you and Happy Studying.

[@jawatu6326]

Why is it formation and not ΔΗat you make 1 mole of gaseous atom from its standard state

[@zubair4875]

Why are we writing 1/2 cl2?

[@ChadsPrep]

Hey Zubair! This is so that we have the same number of atoms on the left and right. Each Na bonds with 1 Cl atom to form NaCl. Since Cl exists as Cl2 naturally we need half of this to form on NaCl.

Chad, as always great lesson!! 😊Very helpful. I actually have a question about ionization energy and electronegativity. I understand that the more shells there are, the weaker the bonds. But i am having trouble with the second factor. What is the rule that affects electronegativity and ionization energy levels? If there are more electrons in valence shell is it weaker/ higher or less. It's all getting mixed up in my head. The top to to bottom and left to right rule is confusing. Thanks again for your course!!!

[@ThunderSpear-b7q]

Isn't lattice energy exothermic (-ve) tho

[@ChadsPrep]

Lattice energy is indeed exothermic, where in the video did you think this was contradicted?

[@ThunderSpear-b7q]

@@ChadsPrep I mean u put your final answer in +ve , which implies an endothermic right? or is it that the -ve of the lattice energy would be +ve

[@ChadsPrep]

can you give me the time in the video?
