Answer:

A) saturated

Explanation:

In an unsaturated solution, the solute is lower than the solvent in the chemical solution. When this occur, there is higher rate of dissolution of the solute in the solvent

A saturated solution is said to be a chemical solution in which the concentration of solute that is dissolving in the solvent is of equal proportion and at maximum  amount,

In a supersatured solution, there exists more solute than the solvent in the chemical solution. When this occur, there is higher rate of crystallization of the solute in the solvent

A solubility curve helps to show a diagrammatic graphical based representation of the amount of solute that is required to dissolve in a given amount of solvent at different temperatures.

Thus, potassium iodide is indeed soluble in water. At 20°C, it is said that the solubility of potassium iodide is 140 grams per 100 cm³ of water. This is similar to the 180 grams of potassium iodide which dissolves in 100 cm³ of water at 30°C because increase in temperature also increases the solubility of a solute in a solvent.

Summarize the relationship between an electron's energy level and its location in an atom
FromTheMoon [43]

Answer:

The further an electron is from the nucleus. the greater its energy level.

Explanation:

When an electron is close to the nucleus, it is at as low an energy level as it can get.

We must put energy into an electron to pull it away from the attraction of a nucleus.

So, electrons that are further from the nucleus are at higher energy levels.

HELP PLEASE!! (100 points)
MrRa [10]

Answer:

As you cool a matter to absolute zero, their kinetic energy reduces significantly and the molecules slows down and begins to aggregate together. ... As heat is added, the molecules gain more kinetic energy. This shown in their increase motion. When heat is withdrawn, the particles slows down hope this helped
