The branch of chemistry that the chemist might use will be the branch of <em>organic chemistry</em>. This is because gasoline is an organic compound. We can say that a compound is organic if it contains a carbon atom. Gasoline is composed of long chains of alkanes (hydrocarbons with single bonds) ranging from 4 carbon atoms to 12 carbon atoms.

Answer: Organic chemistry

Explanation:

As the chemist is studying two forms of gasoline, where both are organic chemicals hence they belong to organic chemistry as the branch. Also, the two forms of the refined gasoline can be used to study other features of gasoline in organic chemistry and the experiment can be help to analyze the gasoline in many ways.

Sladkaya [172]

M1 = 17.45 M

M2 = 0.83 M

V2 = 250 ml

M1. V1= M2. V2

V1 = (M2. V2)/M1 = (0.83× 250)/ 17.45= 11.89 ml

xeze [42]

Answer:

Selenium

Explanation:

Oxygen is present in the group sixteen.

This group consist of oxygen, sulfur, selenium, tellurium and polonium.

All of these have same number of valance electrons thus they show similar properties.

From the given list of elements only selenium is belong to oxygen family thus it has properties similar to the oxygen.

Electronic configuration of oxygen:

O = [He] 2s² 2p⁴

Electronic configuration of selenium:

Se = [Ar] 3d¹⁰ 4s² 4p⁴

While aluminium, boron and phosphorus are belongs to other groups that's why their properties are not similar to the phosphorus.

phosphorus is present in group 15.

Boron and aluminium are present in group 13.
