Look for the compound which in a dilute solution has the most ions. for instance, in b
KNO3 is completed ionized,2 ions per molecule
Ca(NO3)2, three ions, but one of them carries two charges, so in fact one moleucle can break up to carry 5 net charges.
HNO3, 100 precent dissoacated, but two ions per molecule.
Answer: circle calcium nitrate.
I still don't understand. Can someone help, and elaborate more?
for B Ca(NO3)2 is NOT the right answer. i got it wrong.
lol UCI students
Yes, UCI students. We haven't learned this in lecture.
I know that HCl is one of the correct choices
d. K2CO3, also in the lab we did. it all depends on the cation (k, li, and na) which one has the highest mass
e. AlCl3 (that was in the lab we did.)
you are my hero.
its wrong...^^^^^^^ is wrong!! :(
never mind!!!! its right lol! dude u guys.. my chem teacher didn't go over this neither did the TA.....
You are seriously my hero.
you are amazing!
UCI FTW. Haha webworks has NOTHING to do with lecture. They don't correspond, it suuuucckkks.
omgggg yay..i thought i was never going to figure this out....i freaking HATE webworks
Do we really need to know all of this for the lecture AND lab??
Are these going to be on the test?
chem lab uci 2012! suffering with this a year later =/
YEA UCI chem lab where 2units > 4 units
Thank gosh... herooooo.... I have no clue with these webwork question
