Question #2304c

Answer 1

Do you mean is it wrong to write this reaction:

`2NaCl(s) rarr 2Na^(+)(aq) + 2Cl^(-)(aq)`

Explanation:

Of course it would depend on the context. For instance, I could take `116.88` `g` of salt, and dissolve it up in water, and THEN react this quantity with 1/2 a mole of `AgNO_3(aq)`. How much `Cl^-` would be left?

In general, we would try to simplify the coefficients.
