The only option that makes sense is D). Stirring will increase the contact between solute and solvent.

The correct option is D.

When dissolving a substance in a solvent, stirring the solution will increased the rate at which the substance dissolved. This is because, when one stirs a solution, it exposes more surface area of the solute to the solvent, thus, increasing the interaction between the solute and the solvent. The higher the quantity of the solute that is exposed to the solvent, the higher the rate of dissolution of the solute.

Which one of the following best represents the predicted approximate chemical shift and coupling for the hydrogen(s) indicated w
melomori [17]

Answer:

The answer is quartet 2.40 ppm.

Note: Kindly find an attached image below for the part of the solution to this question

Sources: The image was researched from Course hero platform

Explanation:

Solution

Multiplicity or (n+1) rule:

It helps in determination of multiplicity of an individual proton or individual types of proton which are available in the molecule.

Multiplicity =(n+1)

Thus

The non equivalent protons which are attached from adjacent atom is denoted by n.

Now because there are three non-equivalent protons are present at adjacent carbon of methylene group, hence the multiplicity of methylene hydrogen is given as follows:

The multiplicity will be the same for the two hydrogen's. thus we compute multiplicity only for one  hydrogen atom stated below:

Non- equivalent = 3

Multiplicity = (3 +1)

= 4

= Quartet for 2H

A quartet for 2H indicates that the hydrogen atoms attached from the carbon, which is attached one side from a methyl group and the other side form an atom that have no any hydrogens.

Now due +I effect of carbonyl group, chemical shift value is high for these two hydrogens which is exactly at 2.40 ppm or 2.40 Quartet.

What is the empirical formula for<br> P2S3 ?
tatiyna

Answer : The empirical formula is P_2S_3.

Explanation :

Molecular formula : It is represented by the actual number of the atoms of all the elements present in a compound.

Empirical formula : It is represented by the simplest whole number of the atoms of all the elements present in a compound.

The given molecular formula is P_2S_3.

For determining the empirical formula, we need to determine the valency which is divided by each element to get the empirical formula.

In the given formula, the valence is 1.

So, the empirical formula is P_2S_3.
