Interpretation: The name of the technique for the separation of table salt and pepper is to be interpreted.
Concept introduction:
A mixture consists of two or more components that can be physically separated into their respective components. The mixture can be categorized as homogeneous or heterogeneous depending on how uniform it is.
There are several separation techniques used to separate the components of the mixture. Some common examples of separation techniques are evaporation, distillation, fractional distillation, etc.

Now consider the two bicyclic molecules A. and B. Note that A. is a dianion and B. is a neutral molecule. One of these molecules is a highly reactive compound first characterized in frozen noble gas matrices, that self-reacts rapidly at temperatures above liquid nitrogen temperature. The other compound was isolated at room temperature in the early 1960s, and is a stable ligand used in organometallic chemistry. Which molecule is the more stable molecule, and why?arrow_forward
