<u>Answer:</u>
<em>The returns of the company as it is given is already large that is 91% and to get an outcome even better is what it is getting now. There should be certain improvements that needs to be applied with the </em><em>help of stoichiometric data gathered.
</em>
<u>Explanation:</u>
Since the cost of materials cannot be affected and have to be bought under similar rate of cost of working or process can be decreased. By using machines calculation and mechanical devices this come would be accurate and the laws would be minimised. Hence the companies outcome would increase.
Answer:
C- the breakdown of rock into sediment
Explanation:
Because sedimentary rocks have layers and are made of of those layers which are made up of the breakdown of rock into sediment.

Find the Molecular mass of all atoms in the chemical formula and divide it with the mass of the sunstance to get the amount of moles
It is given that the charge on potassium is +1 i.e. Potassium is a cation, K⁺
The charge on selenium is given as -2, i.e. selenium is an anion, Se²⁻
The two ions are shown to combine to form a molecule: KXSeY where X and Y correspond to the proportions in which the two atoms combine.
Since the molecule is neutral, the positive and negative charges need to be balanced. This is possible only if 2 units of K⁺ combines with 1 unit of Se²⁻.
Therefore, the formula would be K₂Se
X = 2 and Y = 1
THE METAL IS THE ELEMENT AND IDK IM GUESSING
