It shows the answer in the text.
Explanation:
On dissolution of chromium(II) sulfate is water 2 ions of chromium(III) ion and and 3 sulfate ions are formed.
The balanced chemical equations of the dissolution of chromium (II) sulfate:

On dissolution of gold(III)nitrate is water 1 ions of gold(III) ions and and 3 ions of nitrate ions are formed.
The balanced chemical equations of the dissolution of gold(III) nitrate:

The bacterial endospores are microorganisms formed due to nutrient deprivation. These are placed first on a paper strip and not directly in the fermentation broth because these microorganisms are very resistance, thus, they need to adjust to the environment first before being acclimated to it.
The longest hydrocarbon chain in the given compound is hexane, therefore it is the parent chain to be considered with one methyl group attached to the 3rd carbon and one chloro attached on the 2nd carbon, therefore the name of the compound is 2-chloro-3-methylhexane
The masses of the liquids are different making them have different densities
