Consider the molecules H2O, H2S, H2Se, and H2Te. Which do you expect to have the highest boiling point, and why? H2O, because it experiences hydrogen bonding.
H2S, because it dissociates and forms ions.
H2Se, because it experiences ion-dipole forces.
H2Te, because it has the most electrons to form a dipole.

The most efficient way to establish the best possible economizer position is to measure

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
