(a)
Interpretation:
The given diagram has to be classified as a mixture, an element or a compound.
The given diagram is,
Figure 1
Concept Introduction:
Matter can be classified into two type’s namely pure substance and mixture.
Pure substance: A single component that has a constant composition, irrespective of the
Example: Water, sugar etc.
A pure substance can be classified into an element and a compound.
Element: A pure substance, which cannot be broken down into smaller substances by a
Example: Hydrogen gas, Magnesium ribbon and copper wire etc.
Compound: A pure substance that is formed by combination of two or more elements by chemical process is called as a compound. Example: Sodium chloride is a compound because it is formed from elements sodium and chlorine.
Mixture: A mixture consists of more than one substance and the composition of a mixture is dependent on the sample. The separation of mixture into its components can be done by physical changes.

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
