Answer:
Paper chromatography would separate the pigments into several bands that appear green or yellow/orange.
Explanation:
Chloroplasts have a mixture of pigments with different colors: intense green chlorophyll-a, green chlorophyll-b, yellow carotenes and orange-yellow xanthophylls, in different proportions. All these substances have a different degree of solubility in non-polar solvents, which allows their separation when a solution of them ascends by capillarity through a porous paper strip, vertically arranged on a film of an organic solvent, where the most soluble move faster, and the less soluble move less on the filter paper strip. Therefore, several bands of different colors will appear that will be more or less distant from the solution according to the greater or lesser solubility of the pigments.
Answer:
In chemistry, a structural isomer (or constitutional isomer in the IUPAC nomenclature) of a compound is another compound whose molecule has the same number of atoms of each element, but with logically distinct bonds between them. The term metamer was formerly used for the same concept.

Because i learnt this before and i aced a test about it dont worry
Answer:
Option c. It contians ionic bonds
Explanation:
Let's take as an example NaCl
An element from group 1 (alkali) with an halogen.
Elements from group 1 form cations with +1 (charge)
This ionic salt, can't never has the formula XZ₂
Ionic salts, also can be dissolved in water, and they don't contain covalent bonds.
