The formula unit equation for the given reaction occurring in water is
CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq).
<h3>What is chemical reaction?</h3>
Chemical reactions are those reaction in which reactant molecules react with each other for the formation of product.
When calcium sulfide reacts with iron (II) bromide for the formation of iron(II) sulfide and calcium bromide will be represented through the following equation:
CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq)
Above reaction best explains the formula unit of given reaction as all valency of atoms are satisfied there.
Hence, the required formula unit is CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq).

Below is an attachment of the Lewis structure with the lowest formal charges.
The formal charge is the fictitious charge that an atom in a molecule would have if the electrons in the bonds were evenly distributed among the atoms. The nonbonding electrons on a neutral atom are subtracted from its valence electron count, which is then followed by the number of bonds that bind it to other atoms in the Lewis structure, to get the formal charge. This is another way to put it. When hyponitrous acid is oxidized in the atmosphere, nitric and nitrous acids are produced. By reducing a nitrate or nitrite by sodium amalgam in the presence of water, hyponitrite salts have been created.

Partial pressure the the amount of pressure exerted from a mixture of gasses. So the total pressure of the solution will be the sum of the partial pressure, even if a constituent has is inert.
Explanation:
Density is defined as the mass of the substance divided by the volume of the substance.
Mathematically, Density =
Since, it is given that mass is 18,754 kg and density is 0.788 g/. We know that there are 1000 grams in 1 kg.
So, 18,754 kg equals 18,754000 grams.
Hence, calculate the volume of the waste collection tank as follows.
Density =
0.788 g/ =
volume = 23799492.38
It is known that 1 equals 0.001 liter. So, 23799492.38 equals 23799.49 liters.
Thus, we can conclude that volume of the waste collection tank is 23799.49 liters.
