1. which of the following can take the shape of the container it is in but has a fixed volume? . a. argon gas. b. liquid bromine. c. solid water. d. hydrogen plasma. 2 . in which of these samples do the molecules have the greatest kinetic energy? a. solid ice (-25 °c). b. water vapor (102°c). c. ice water (0°c). d. liquid water (54°c).

The correct answer for the first question is liquid bromine. Liquids take the shape of its container but has a fixed volume. The correct answer for the second question is B. Water Vapor. Kinetic energy is a function of temperature, thus molecules at a higher temperature will have high Kinetic energy. In the choices given, water vapor has the highest temperature therefore it has the greatest kinetic energy.

Answerthe half-reaction having the greatest tendency to occur at the anode:     i₂(aq) + 2e⁻  ⇄ 2i⁻  ;   e = +0.53 v======oxidation occurs at the anode. we must therefore find the half-reaction with the greatest tendency to oxidize.the given values of e are reduction potentials (the form of the half-reactions are of reduction).the lower the reduction potential, the higher the potential to oxidize. the half-cell with the lowest reduction potential will have the greatest tendency to oxidize at the anode.the half-reaction having the greatest tendency must be    i₂(aq) + 2e⁻  ⇄ 2i⁻    e = +0.53 vbecause its reduction potential is the lowest out of the three.

C, small, hard spheres with insignificant volumes
