When elements transfer electrons from a cation and an anion it called ionic bond.
The correct option is D. 0.2 M CaCl2 is has the lowest freezing point.
<h3>What is aqueous solution?</h3>
When one significance liquefies into another, a solution is formed. A solution is a homogenous mixture consisting of a solute dissolved into a solvent. The solute is the essence that is being dissolved, while the solvent is the dissolving medium. Solutions can be formed with multiple different classifications and forms of solutes and solvents. In this branch, we will focus on a resolution where the solvent is water.
- An aqueous solution is a moisture that contains one or more dissolved essence. The dissolved importance in an aqueous solution may be solids, gases, or different liquids.
- In directive to be a true solution, an assortment must be stable. When sugar is fully dissolved into moisture, it can stand for an undetermined amount of time, and the sugar will not recompense out of the solution. Further, if the sugar-water solution is passed through a filter, it will stay with the water.
- This is because the liquefied particles in a resolution are very small, usually less than 1nm in diameter. Solute particles can be atoms, ions, or molecules, counting on the type of essence that has been dissolved.

Answer:
I could create a slower reaction because the particles might be moving slower due to the cold. if it was warm there will be a faster reaction. similar to the elements movements in solids and liquids.
Remember the formula as per the second Law of Newton: F = m*a
And also remember that the weight is the force with which the mass is attracted by the planet (or satellite in the case of the moon).
With that information you can answer the questions:
a) Weight = F = m*a
m = 175 slugs = 175 lbm
i) Earth
a = 32.17 ft/s^2
Weight on Earth = 175 lbm * 32.17 ft / s^2 = 5,629.75 poundal
ii) Moon
a = [1/6] 32.17 ft/s^2
Weight on the Moon = [1/6]*5,629.75 poundal = 938.29 poundal
b) Force = 355 poundal
m = 25.0 slug
a in m/s^2 = ?
First calculate the force in ft/s^2
F = m*a => a = F/m = 355 poundal / 25.0 slug = 14.2 ft/s^2
Conversion:
14.2 ft / s^2 * [ 0.3048 m/ft] = 4.32816 m/s^2
Answer: 4.33 m/s^2
