Im a bit torn here, lets look at the definitions of physical and chemical changes:
physical change changes only the phase/state of a substance, but not what the substance is
chemical change is a chemical reaction where a new substance is formed and energy is given off or absorbed.
(it just started raining and it smells really nice out my window)

clearly, this cannot be just a physical reaction. i think i would be inclined to pick B. but C. could have merit as an answer too. sorry for the ambiguity x

Paper chromatography is a technique used to separate molecules based upon their size and solubility in a particular solvent. If
dalvyx [7]

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.

The third thing I notice is that all planets have one element that makes up 75% or more of its atmosphere except Mercury.

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.


Lattice energy is the key to the formation of a salt because without that energy it wouldn't form, it makes the overall process spontaneous
