yeah I'm alright just had a couple visit to the dentist got a root canal done and had 7 fillings also done and today just a few minutes ago one of my braces' brackets fell off and the orthodontist isn't in until Saturday so I'll have to deal with the wire pushing in on my gum and teeth for a while also the gyms opened on sunday and I have been working out but also got super sore because I haven't worked out in a month which sucks because I can't walk correctly until it goes away
and I have exams starting next week beginning with chemistry and uhhh what else? nothing much else I guess all in all I would say pretty uneventful how are you doing?

Pretty unventful? You've been having a time of it, I'd say.
Sucks about your teeth, but why'd you have to get 7 fillings done? I'll send you some toothbrushes, this'll never happen again.
Good luck with the chemistry, I'm having my own chemistry issues as well.
Other than that, things're busy and crazy at work, but overall not too bad yet, things could get a lot worse though.

>>3871586
it requires more energy to break one mol LiF than it does to break BaCl2 right?
>>
>>3871692
Correct.
I imagine they want you to get to that answer by using the periodic table and knowing the electronegativity trend. In which fluorine (at the top right) is the most electronegative at ~4, and francium (bottom left) is the least at ~0.7.So as you move up and to the right, electronegativity increases.
Electronegativity, being an indicator of the strength of an atom's electron's ability to attract positive charges (other atoms), is used to gauge bond strength. The greater the difference in electronegativity between two atoms, the greatets the bond strength is, and the more energy it'd take to break that bond.
LiF has a greatest difference than BaCl2, so the LiF bond is stronger and requires more energy to break.

You can verify that by looking up the heat of formation for both LiF and BaCl2. LiF has a heat of formation of -1017 kJ/mol and BaCl2 is -799 kJ/mol. Essentially the heat of formation is how much energy is exchanged when a compound is formed. When LiF is formed from Li+ and F-, it releases 1017 kJ per mol to form LiF. It's the same in reverse, to break LiF, 1017 kJ/mol must be supplied, that's the energy required to break LiF.

I think the question might throw some people off because LiF has one ionic bond (only 2 atoms in the molecule) and BaCl2 has two ionic bonds (3 atoms in the molecule). Which is an interesting thing to think about and I'm not entirely sure why it's less energy to break BaCl2's two ionic bonds than it is to break a single LiF ionic bond even though the electronegativity difference isn't that great.

But the answer that LiF takes more energy to break than BaCl2 is supported by the heat of formation for both, and by the periodic table electronegativity trend (which is the method I assume they want you to use), so I hope that helps you.

Yeah that is what I thought too but apparently I’m wrong somehow because there are more bonds in the BaCl2 salt than in LiF ? Very weird if you have a way to or equation or whatever that could help I would be thankful

Aye
>>3872317
Yeah I figured it might be a tricky question like that. Not entirely sure on how to explain the answer. It makes sense in terms of comparing the bond energies, Li-F is greater than Ba-Cl, but Ba-Cl has two bonds, so it makes sense to be greater. But based on the heat of fusion, which is the amount of energy needed to break LiF into Li+ and F-, and BaCl2 into Ba2+ and 2Cl-, it seems that LiF is still more energetic.
Try to look up bond energies of both, I'm sure there's a table out there somewhere.

I have a table but the thing is that it doesn't have BaCl2 in it that is the only thing that makes me unable to refute the teacher

I think one of the previous tables I looked at was wrong/misleading, looks like BaCl2's heat of formation is greater than LiF's.
Look that one up, their heats of formation are well documented.
