Answer:

The correct answer is sedimentary rock.

Explanation:

The sedimentary rocks are the types of rocks, which are produced due to the deposition and the succeeding cementation of that substance at the shallow part of the Earth and within the water bodies. In the geological sciences, sedimentation refers to the procedure of the deposition of the solid substance from a state of solution or suspension in a fluid, that is, water or air.

Why is 15 m acetic acid an appropriate solvent in which to perform rate studies of electrophilic bromintations?.
Alekssandra [29.7K]

Acetic acid activates the bromine and makes it a better electrophile.

<h3>What is bromination?</h3>

When a substance undergoes bromination, bromine is added to the compound as a result of the chemical reaction. After bromination, the result will have different properties from the initial reactant.

<h3>Why is 15M acetic acid used as a solvent for bromination?</h3>

DCM (dichloromethane) requires more time. Acetic acid has protons that can give one of the Br (bromine) a positive charge and activate it. There is a brief loss of aromaticity that calls for high energy activation.

Refer to the attached image for bromination reaction.

According to the law of conservation of mass, if an element A has an atomic mass of 2 mass units and element B has an atomic mas
LenaWriter [7]
The law of conservation of mass states that mass is neither created nor destroyed. Since we have 2 g/mol of A and 3 g/mol of B then AB should be equal to the sum of their molar mass that is 

2 g/mol + 3 g/mol = 5 g/mol AB

for the case of A2B3

A2 = 2 * 2 = 4 g/mol
B3 = 3 * 3 = 9 g/mol

therefore A2B3 = 13 g/mol
