It is called 'answers' and not hints.
39) NaNO3 + PbI2--that would be 'd' . . . and . . .
40) Double replacement 'd'.
Get an "A".

If you look at the charges of the components of the molecule, you'll find that (d) is the correct answer.
This is a double replacement reaction, with each ion ending up with a different partner.

These are really simple questions that you should be able to answer.
I helped you with one. You can do the rest.
In fact, it takes you much more energy to key the question onto Yahoo Answer than it would for you to answer them yourself.
Being lazy always take more energy.
