I am trying to buy continental bike tube - 700 x 25, but the size change to 700 x 32-42 pv on the cart. why?

I found the same problem and had to buy it from a different source in order to be sure I was getting the correct size. It’s an amazon problem.

Is this 650cc or 700cc? The name says 650 but the picture shows 700

It is 650cc. Bought to install on my older SCOTT road bike.

Will it fit a 25x700c tire?

Yes. I just put these in my 25x700 and they fit.

will this work on a trek fx3? I'm confused about the length of the valve for this bike? 42mm OK or longer?

This has nothing to do with the bike but rather with the wheel or more specifically with depth of the wheel. If you wheel is X mm deep you will need at least X +15 mm long valve. Example: you wheel rim is 25mm deep. You will want tube with at least 40mm valve. Longer is OK but at some point it will impair the aesthetics.
