Question
Water exists in different forms depending on the pressure and temperature. A portion the phase diagram for ice I, ice III and liquid water is shown below. What statement about the densities of three phases is correct. a. The density of liquid water is greater than the densities of either ice or ice III. b. The density of ice III is greater than the densities of either ice liquid water. c. The density of ice I is greater than the densities of either ice III or liquid water. d. The density of ice I and ice III are equal and they are both denser than the density liquid water. The electron affinities of five elements are given below. Which statement best explains why the electron affinity at phosphorus does not follow the general trend. _13Al 12 kcal/mole _14Si 32 kcal/mole _15P 17 kcal/mole _16S 48 kcal/mole _17Cl 87 kcal/mole
Explanation / Answer
35) (A) The density of liquid water is greater.
(36)
Because of phosphorous has half filled elecrtronic configuration in its valece shell, due to which it is in some how more stable state. So, it has less affinity towards electron than the expected.
