@kristinatime what do you think the answer is?
I think it's D
interesting, what is your reasoning?
@kristinatime tell me your reasoning and I'll walk you through it
I'm not sure I just think lithium would create a high melting point, I'm terrible at chemistry so I need help explaining these things /:
Melting point depends on intermolecular attractions and the crystalline structure.
Well what do you guys think it is?
Thing is (it's melting point not boiling point) so @kristinatime whenever you have to determine whether a compound has a higher melting point, always identify which compound is found in the solid phase.
because essentially we're going from solid to liquid i.e. MELTING.
Oh okay I'm understanding it a bit better
why would the other answers not make sense @kristinatime? could you tell me a little about those?
Actually LiCl is a gas element so that wouldn't have a melting point lol so I'm not sure. Water can't melt so it isn't h2o. So...
It has to be NH3 or C6H6
@kiristinatime dont confuse yourself. remember LiCl is a solid at Room-temperatue. why? because it's ionic, Li is a metal and Cl is a non metal. whenever we have a metal and a non metal the result is an ionic compound. now Water, Benzene, and ammonia are all liquids at room temperature. that's because of the type of bonding too as well.
So it would be LiCl?
@kristinatime i'll give you another one Which has the highest melting point and why? KCl Cl2 C6H6 H2O
So would it be LiCl or no? And hmmmm
Not sure maybe C6H6
always provide your reasoning
I honestly don't know
LOL why won't you tell me if I was right on the first question?
I believe it's lithium because ionic compounds are solids at room temperature right? because they have an electrostatic attraction. between the metal and non metal. does this make sense?
Makes total sense actually
so yeah i tried to give you another problem I posted it above
so tell me why the others aren't good answers and go through them individually @kristinatime
Uhhh idk haha
the biggest concept with melting point is that you need to ask yourself what compounds are solids at room temperature right? because solid --> liquid that's what melting is.
In order to answer questions like these, you need to know about intermolecular forces, rank these in terms of strength, and be able to identify which compounds have which. |dw:1444054209829:dw| read this http://www.chem.sc.edu/faculty/shimizu/333/Chem_333/2b.i.html
