Concept explainers
(a)
Interpretation:
The given compound is to be identified as either an ionic compound (i.e., one containing ionic bonds) or a covalent compound (i.e., one containing only covalent bonds).
Concept introduction:
If elements in a compound have large electronegativity differences, ionic bonding can occur. A more electronegative atom acquires electrons given up by a less electronegative atom forming oppositely charged ions. The electrostatic attraction between the positively charged cations and negatively charged anions forms the ionic bond. Most ionic compounds consist of a metal (the elements from left side of the periodic table) and a non metal (the elements from right side of the periodic table), whereas most covalent compounds consist of nonmetals only.

- 32. Consider a two-state system in which the low energy level is 300 J mol 1 and the higher energy level is 800 J mol 1, and the temperature is 300 K. Find the population of each level. Hint: Pay attention to your units. A. What is the partition function for this system? B. What are the populations of each level? Now instead, consider a system with energy levels of 0 J mol C. Now what is the partition function? D. And what are the populations of the two levels? E. Finally, repeat the second calculation at 500 K. and 500 J mol 1 at 300 K. F. What do you notice about the populations as you increase the temperature? At what temperature would you expect the states to have equal populations?arrow_forward30. We will derive the forms of the molecular partition functions for atoms and molecules shortly in class, but the partition function that describes the translational and rotational motion of a homonuclear diatomic molecule is given by Itrans (V,T) = = 2πmkBT h² V grot (T) 4π²IKBT h² Where h is Planck's constant and I is molecular moment of inertia. The overall partition function is qmolec Qtrans qrot. Find the energy, enthalpy, entropy, and Helmholtz free energy for the translational and rotational modes of 1 mole of oxygen molecules and 1 mole of iodine molecules at 50 K and at 300 K and with a volume of 1 m³.
