Answer:
c
Explanation:
it must absorb electrical energy
Answer:
unsaturated
Explanation:
All solutions have a definite capacity of dissolving solute in it.
Unsaturated solutions are the solutions which contain less amount of solute than the maximum capacity of dissolving the solute. If more amount of solute is added in such a way a point is reached where addition of more solute cannot be dissolved. The solution is known as saturated solution.
Amount dissolved > Maximum solubility limit, the solution is saturated.
Amount dissolved < Maximum solubility limit, the solution is unsaturated.
If the amount of the salt exceeds the solubility limit, then the solution is saturated solution. If it is less than the limit given, then it is unsaturated solution.
The solubility = 0.667 grams per liter
Amount dissolved = 0.502 grams per liter
Since,
Amount dissolved < Maximum solubility limit, the solution is unsaturated.
The gravitational potential energy of a basketball : PE = 18.375 J

Given
height = h = 3 m
mass = 0.625 kg
Required
The potential energy
Solution
The energy produced from its position is called potential energy (PE)
which can be formulated as:
PE = m. g. h
(g = 9.8 m/s²)
Input the value :
PE = 0.625 x 9.8 x 3
PE = 18.375 J
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°.
