Born-Haber Cycle for MgCl2, Magnesium Chloride

The Born-Haber Cycle shows the energies required (and released) when elements (like Mg and Cl2) are converted into their ionic form. One path is straight from elemental form to ionic form; the other involves vaporizing, atomizing, and ionizing to gas-phase ions, then using the lattice enthalpy.

watched this literally 2 hours before exam, saved my life. thank youuuu

my exam is literally in 10 minutes. This saved me.

at 4:24 , isn't it the enthalpy of sublimation ?

Thanks. I needed this

[@Knightmare445]

Thank you so much sir. This helped me a lot with my homework.

Thank you! Very helpful.

Thank you for explaning !😊👍

[@apolloalexander2251]

I love this guy... hes so positive
I'm 13 and I understood this

[@kalpanashedthy3101]

@Merlin dude there are some syllabus which cover lot of topics for students at an early age or else he is studying this himself for fun.

[@fatimafahad2531]

woooow thx , u saving my life man !!!

[@wuuekywuueky869]

Hi, what the defference between Born-Haber and Haber-Bosch.
Please Help me...

Thank you!

[@nijanaemovon7152]

Great video

[@henidarguech2142]

from solid to gas is a sublumation not a vap

[@panpanp657]

Thanks dude u are amaizing

[@kingsleyjohn4213]

Thank you so much Sir. Kindly permit me to share this with my students on classroom channel.

[@umaarabdullah8814]

You're awesome

[@sachirasamarakoon1554]

Hey sir . Isn't it Delta H s for the making Mg solid form in to Gas form ??? 🧐im bit confused there

[@EiliyahK]

Delta H atomisation energy, (enthalpy)

[@panchetawest30]

Hi. Can you please send me an email that I can email you on? I would love to ask you a few questions.

[@belaachie1244]

Pls sir I don't understand how there is now a 2 in front of chloride but from the start we had but Cl2

[@susanzhu2928]

It’s the bond dissociation energy, which we did to break the bonds between Cl2 to get 2 Cl atoms

[@faizahbegum5257]

Why do we need to change cl2 to 2cl what is the difference and what is the purpose of this step

[@twinomugishawinniefred2887]

Thnx sooooo much coz now am steady

[@malm3048]

but sir the lattice enthalpy is always exothermic isn't it? since the lattice enthalpy is the change when one mole of an ionic compound is formed from its gaseous state under standard conditions, so is the formation of a bond where energy is released (3:11)

[@yoh7605]

Lattice enthalpy can be said as being exothermic or endothermic. If it says it should be exothermic in your syllabus then just put the arrow down 😁

[@ehsaanulhaque1857]

Lattice Energy can only ever be exothermic.

[@nothingmatters2022]

Yes

[@ashungafackgodi6525]

Woooow

[@h0rrify]

Love u

[@rahickmahabub7255]

Should lattice energy be exothermic in this one . (As it’s the energy release when one mole of an ionic solid is formed from require amount of gaseous ions)
Also ur forming a bond here … so should be exothermic

[@chemistNATE]

This depends on the “definition” of lattice energy that your teacher / textbook / country uses
Unfortunately I have seen it done both ways. The NUMBER is the same but the SIGN is different.
I always learned lattice energy as energy REQUIRED to break the solid apart, but you may be correct in your own jurisdiction

[@CodeGamerProgene]

That's my teacher's way

[@igortelles6779]

my boy is calmly explaining Born-Haber cycle while the camera is insanely changing the white balance

[@nothingmatters2022]

It’s exothermic

[@andrewhuss1505]
