## anonymous 5 years ago BaCl2+ NaCl--->

1. Xishem

Seeing as there is no driving force for the reaction (i.e., no precipitate, water, or gas would form; it's not a redox reaction), no reaction would occur. $BaCl_{2}+NaCl \rightarrow NR$

so how do u determine their states?

3. Xishem

There are no products, so there is no way to determine their states. There is no reaction that occurs between those two compounds.

4. anonymous

yeah i just realised that

5. anonymous

but in general how do u determine the sates of your product after the reatants do react

6. anonymous

how do u know whether is solid,aqueous or gas

7. Xishem

It depends what type of reaction it is. To determine the products of a reaction, you need to know if it's a precipitation reaction, acid-base reduction reaction, gas-forming reaction, or redox reaction. If it's a precipitation reaction, the cations of each reactant bond with the anion of the other cation. The precipitate, which will be (s) is determined by solubility rules ( http://www.files.chem.vt.edu/RVGS/ACT/notes/solubility_rules.html), and the other product is in aqueous sol'n If it's an acid-base reduction reaction, the products are always a salt (in aqueous sol'n) and water (liquid). If it's a gas-forming reaction, it's a salt (aq), some gas (g), and sometimes water (l) Redox reactions are much harder to predict products for.

ok thanks,let me read it up right away :)
