Which of the following are ionic, and which are molecular? (a) PF5: Molecular (b) NaI: Ionic (c) SCl2: Molecular (d) Ca (NO3)2: Ionic (e) FeCl3: Ionic (f) LaP: Ionic (g) Co (CO3): Ionic (h)N2O4:Molecular
here is the other one.... A match is lit and held under a cold piece of metal. The following observations are made: (a) The match burns (b) The metal gets warmer (c) Water condenses on the metal (d) Soot (carbon) is deposited on the metal. Which of these occurrences are due to physical changes, and which are due to chemical changes. Physical changes: B, C, D Chemical changes: A This question I was certain of the answer but then I conversed with a fellow classmate and they argued their responses so I kind of got in between feelings about it. Can you explain it a little bit?
Too many. too long.
its right. for the first, I would double check the electronegativity differences between some of them, like PF5
Ok thank you so much. I appreciate it. At least you were more of a help than abb0t hahaa. No but I really appreciate it.
Not dissing abb0t here but you know what I mean or at least I think you do. Anyways yea
Oh yea I kind of fanned you so yea
Not a stalker or creep I PROMISE
nah, abb0t's comment is it's not with bad intentions. A lot of people here just post huge blocks of writing and except people to read through them. Part of the site's policy is that you only post 1 question per thread. haha yeah man no worries, i fanned you back.
OOPS
No but I was only kidding about abb0t. I have a bad sense of humor i guess hah
haha it's all good. i doubt he cares
yea but if he does... Sorry if I offended you Mr. abb0t (your real name is not evident). It was all out of pure intentions. If I hurt your feelings well I'm sorry. :) There. My public apology. Anything I should change about it? no Im kidding but yea I don't think he cares but still just in case.
