Part 1. De-chlorinated water is water that doesn't contain any chlorine.
Part 2. Tap water contains chlorine, the chlorine should be removed from the water before putting in an aquarium. This is because Chlorine is known for cleaning and killing micro-organisms. It should not be put into an aquarium because it can be harmful to the life inside of it.
Part 3. There are various ways to de-chlorinate water. One of the ways is by dissolving a tablet of potassium <span>metabisulfite into it. 1 tablet = 20 gallons of water dechlorinated.

Answer:
Volume
Explanation:
In chemistry, the CONCENTRATION of a solution is the amount of a substance present within a volume of another substance. In other words, the concentration refers to the amount of a solute dissolved in a particular volume of a solvent to make a solution.
Concentration can be expressed in mass per volume i.e. g/cm³ or mol per volume i.e. mol/L or mol/dm³ etc. The amount of a substance is measured in Mass or mole, while the volume of a substance in Litres (L).
The answer is false it wouldnt be true
The correct answer is class.
Taxonomic category (rank) is the level of a group of organisms in a taxonomic hierarchy. The major ranks are domain, kingdom, phylum, class, order, family, genus, and species. Higher rank has more general characteristics of organisms. The lowest rank-species contains most specific descriptions of life forms in it.
Theoretically it is the Chargaff's rule which entails that the ratio of purines and pyrimidines are 1. So following that rule you can solve this question.
G (purine) = C (pyrimidine) and
A (purine) = T (pyrimidine)
So G + C would be 28% and hence
A +C would be 72% i.e. 36% each.
Please note that their are certain modified bases besides these four are also there including methyl Cytosine, Methylated Adenine. But htese modification does not violate the Chargaff's rule and they follow standard Watson Crick base pairing.
