  1. (a) Coefficients represent molecules, or formula units, or moles, depending on the situation.
    (b) Removing air from a sealed container reduces the pressure inside it. How this affects the container, depends on the strength and rigidity of the container.
    (c) Polar solvents dissolve polar and ionic solutes and nonpolar solvents dissolve nonpolar solutes.
    (d) The freezing point of a solution is always lower than the freezing point of the pure liquid.
    (e) Spontaneous reactions have low activation energy
