(WCSP24)  Shown below are five curves that represent the distribution of molecular speeds of five different gases at the same temperature and pressure, each in a separate 10 L container. The gases are H2, CH4, He, SF6, and N2. Complete the statements so that they are true.   a. The gas represented by [drop1] has the largest fraction of molecules traveling at the most probable speed. b. Curve [drop2] corresponds to N2. c.  All of the gases represented have the same [drop3]. d.  Gas [drop4] has the greatest density. e.  Decreasing the speed of the molecules will [drop5] the pressure.

(WCSP24)  The cross sections of three different ionic compounds (labeled Compound 1, 2 and 3) are displayed in the figures below. In the figures, the charge on each ion is indicated, and the diameter of each circle reflects the diameter of each ion.    Rank these compounds in order of increasing melting point. lowest [drop1] < [drop2] < [drop3] highest
