A 10.0mL sample of a sugar solution has a mass of 5.0g. What is the density of the sugar solution?
Ludmilka [50]

Answer:

The answer to your question is: density = 0.5 g/ml

Explanation:

Data

Volume = 10 ml

mass = 5 g

Density = ?

Formula

density = mass / volume

Substitution

density = 5/ 10

density = 0.5 g/ml

Suppose that a molecule has four bonding groups and one lone pair on the central atom. Suppose further that the molecule is conf
Grace [21]

Answer:

The bond angles between the axial bonding groups are slightly less than 180°.

The bond angles between the equatorial bonding groups are slightly less than 120°.

Explanation:

Accordign to VSEPR theory, a molecule with four bonding groups and one lone pair on the central atom has a trigonal bipyramidal electronic geometry.

The position of the lone pair can be located in the equatorial position or axial position.

When the lone pair is found in equatorial position, it has two axial groups that repel it and the angle of the lone pair between each axial group is 90°.

When the lone pair is in axial position it has 3 equatorial groups that repel it and the angle of the lone pair between each equatorial group is 90°.

Since the molecule has a lone pair, the most stable geometric structure is when the lone pair is in the equatorial position, because it has fewer repulsions than in the axial position.

The molecular geometry is "seesaw"

The bond angles between the axial bonding groups are slightly less than 180°.

The bond angles between the equatorial bonding groups are slightly less than 120°.
