Interpretation:
The steps of drawing the Lewis structure needs to be explained.
Concept introduction:
Lewis dot structure is also known as Lewis dot formula or electron dot structure. The bond formation between the atoms takes place due to the sharing of valence electrons of bonded atoms while the remaining electrons present in outer shell represented as lone pair of electrons. To draw the Lewis structure, calculate the total number of valence electrons in each atom and draw the structure in such a way that each atom gets its octet configuration.

Answer to Problem 51SSC
- Check the valence electron in each bonded atom.
- Count the total number of valence electrons in the given molecule.
- Draw the Lewis structure between bonded atoms in such a way that each bonded atom will get octet configuration.
- Draw the lone pairs with dot or cross and
chemical bonds with lines.
Explanation of Solution
Lewis dot structure is the representation which shows the bonding between atoms present in a molecule. It shows lone pairs and bond pairs that existing on each bonded atom. Thus to draw the Lewis structure:
- Check the valence electron in each bonded atom.
- Count the total number of valence electrons in the given molecule.
- Draw the Lewis structure between bonded atoms in such a way that each bonded atom will get octet configuration.
- Draw the lone pairs with dot or cross and chemical bonds with lines.
Thus, the Lewis structure of a molecule depends on the valence electrons of all bonded atoms.

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.
