Question
Chapter 4, Problem 11Q
Interpretation Introduction
Interpretation:
The reason to avoid the use of beaker for recrystallization should be determined.
Concept introduction:
Recrystallization is a technique that is used to purify the impure compounds. It is based on the principle that the solubility of substances increases with the increase in temperature.
Following are some of the types of recrystallization:
- Single-solvent recrystallization
- Multi-solvent recrystallization
- Hot filtration-recrystallization

Quantum mechanics. Explain the basis of approximating the summation to an integral in translational motion.
Quantum mechanics. In translational motion, the summation is replaced by an integral when evaluating the partition function. This is correct becausea) the spacing of the translational energy levels is very small compared to the product kTb) the spacing of the translational energy levels is comparable to the product kTc) the spacing of the translational energy levels is very large compared to the product kT
