Only answer if your going to give a correct explained answer to me you so much

1.)list all of the different intermolecular interactions (imfs) that are possible in a solution of cacl2 in methanol (ch3oh)?

2.)which pairs of molecules have the correct boiling point (bp) trend?

bp of cs2 > bp of co2
bp of o2 > bp of h2
bp of sih4 > bp of snh4

3.)based on the information given, which one of these molecules has the weakest intermolecular forces?
substance boiling point (°c)
ch3f −78
ch3cl −42
ch3br 4
ch3i 42
ccl4 77

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
