Intermolecular forces are responsible for which of the following. Select all that apply. Question 5 options: A) Boiling points B) Melting points C) Solubility D) Phase (solid, liquid, gas) at room temperature E) None of the choices are applicable

A) Boiling points

B) Melting points

D) Phase (solid, liquid, gas) at room temperature

Explanation:

Intermolecular forces are attractive forces between molecules. Generally, intermolecular forces are much weaker than intramolecular forces.

All substances exist in one of three states: gas, liquid, or solid. The major difference between the condensed state and the gaseous state is the distance separating molecules.

The boiling points of substances often reflect the strength of the intermolecular forces operating among the molecules. At the boiling point, enough energy must be supplied to overcome the attractive forces among molecules before they can enter the vapor phase. If it takes more energy to separate molecules of substance A than of substance B because A molecules are held together by stronger intermolecular forces, then the boiling point of A is higher than that of B. The same principle applies also to the melting points of the substances. In general, the melting points of substances increase with the strength of the intermolecular forces.

i had this on my unit activity, i can you if you are a plato student. are you a plato student?

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
