Homework Help: chemistry

Posted by lyne on Tuesday, January 13, 2009 at 8:10pm.

predict the identity of the precipitate that forms.

calcium nitrate, Ca(NO3)2, and sodium chloride , NaCl

why does the answer come out as no reaction?

couldnt it form to be CaCl2 or NaNO3

i thought it had something to do with the fact that Na and NO3 are both soluble so they can't go together but that still leaves CaCl2....

help please!!

There is no reaction because none of the following occurred.
Reactions take place for one of the following three reasons:
1. A precipitate (an insoluble material) is formed. If you look, none of the possible combinations are insoluble. (NaNO3 and CaCl2 are the only two other possibilities besides the starting materials.)
2. A gas is formed. (There is no gas in this equation.)
3. A slightly ionized material is formed. (All of the possible combinations are 100% ionized.
4.(These three leave out the possibility of an oxidation-reduction reaction taking place.) Actually, that counts as a fourth reason.
