Please only answer if your going to give a correct explained answer to help me thank 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

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
