explain on a particle basis how the addition of a solute affects the boiling point, the freezing point, and the vapor pressure of the solvent.

Identify the following as either reduction or oxidation: a. 2I^- -> I2 + 2e- (my answer oxidized) b. Zn2+ + 2e^- -> Zn (reduced) could someone check my answers? I remember OIL RIG (oxidation is loss, reduction is gain.) but I'm still uncertain of what I a...

anyone?

the cookie choice seems to be rifght for me they asked about dumb marbles. but your next cookie could be peanut butter or chocolate. It depends on how you picked them. I could be wrong but the cookie choice seems right.

thank you!

the resultant velocity would be 0.00 because you subtract one from the other.

Don't forget to divide the 1/2 out of the equation. 9.8 will become 4.9 a lot of people make the mistake of forgetting to cancel and divide 1/2.

I think I got 27 - 4sqrt3

I'll help with part 1 W=P(delta)V or work=pressure X volume change W=(2.3 atm )(5 x 6.1) W=70.15 J

I'm confused on this one I could really use a second opinion
