Answer:

The motion of the object is changing

Explanation:

Objects will only change their motion (direction, speed) if there is an unbalanced force of some kind acting on them. Balanced forces result in no change in the object's state of motion.

Strike441 [17]
When a solvent has as much of the dilute dissolved in it as possible, then it is saturated.

If you were to heat the water, its capacity would increase and would then be super-saturated because it has more dissolved in it than possible as room temp.

Since there is no heating being done, the water is just saturated.

Hope that helps!

Calculate the molarity of each of the following solutions. Use the periodic table if necessary. A salt solution with a volume of
Andru [333]

The molarity of the NaCl in the 250 ml slat solution is 2.8M.

<h3>What is molarity?</h3>

The molarity of a solution is defined as the concentration of a solute per unit volume of the solution.

Given, the volume of the solution is 250 ml converted into l 0.25

The number of moles of NaCl is 0.70.

By the formula  of molarity

M = \dfrac{n}{V}\\\\\\M = \dfrac{0.70}{0.25} = 2.8 M

Thus, the molarity is 2.8 M.
