The dermis or corium is a layer of skin between the epidermis
Answer:
The answer to your question is maybe letter D, but the last oxygen needs a number 6.
Explanation:
The empirical formula gives the actual elements that form part of a molecule but not the total numbers.
The molecular formula gives the total number of atoms of each element in a molecule.
We must factor the molecular formula to know if a formula is the empirical formula of that.
A. CH₄ C₂H₆ = 2(CH₃) these are not empirical molecular formulas
B. CH₂O C₄H₆O these are not empirical-molecular formulas
C. O₂ O₃ these are not empirical-molecular formulas
D. C₃H₄O₃ C₆H₈O these are not empirical-molecular formulas
the last oxygen needs a number 6 to be
the answer.
Fractional distillation is used for the refining of crude petroleum.
<h3>How are the components of
crude petroleum separated out?</h3>
Fractional distillation is the procedure used to separate crude oil's numerous constituents.
- A mixture is divided into several components, known as fractions, using fractional distillation.
- A combination of hydrocarbons makes up crude oil. The crude oil evaporates, and in the fractionating column, its vapors condense at various temperatures.
- The hydrocarbon molecules in each percent have a comparable number of carbon atoms and a comparable range of boiling points.
- The mixture is placed above a tall fractionating column that has multiple condensers coming off at various heights.
- The bottom of the column is warm, while the top is cool. High boiling point compounds condense at the bottom, whereas low boiling point substances condense as they ascend.
