Venus is making soup. She is putting her ingredients into a pot of water. She places small amounts of the ingredients into water

and heats up the pot on the stove. She slowly stirs the pot on the stove. What should Venus do to speed up the rate the ingredients are dissolving?
A She should place larger amounts of ingredients into the water.
B She should take the pot off of the heat to lower the temperature.
C She should place the pot in the fridge to cool it down.
D She should stir the pot of ingredients faster.

Answer:

Your answer is D

Explanation:

This is the only viable solution due to the fact that first of all the other options would slow down the dissolving of the ingredients, second of all when you are trying to dissolve ingredients faster you should stir faster because when you stir faster you distribute the particle faster thus speeding up the process. Therefore that is my proof that your answer is D.

Hope this Helps!

Answer:

D

Explanation:

increase in rate of stiring leads to an increase in rate of which the ingredients will dissolve

Imagine two solutions with the same concentration and the same boiling point, but one has benzene as the solvent and the other h
11Alexandr11 [23.1K]

Complete question:

Imagine two solutions with the same concentration and the same boiling point, but one has benzene as the solvent and the other has carbon tetrachloride as the solvent. Determine that molal concentration, m (or b), and boiling point, Tb.

benzene boiling point=80.1 Kb=2.53

carbon tetrachloride boiling point=76.8 Kb=5.03

Answer:

m = 1.32 mol/kg

Boiling point: 83.4°C

Explanation:

When a nonvolatile solute is added to a pure solvent, the boiling point of the solvent increases, a phenomenon called ebullioscopy. This happens because of the interactions between the solute and the solvent. The temperature variation (new boiling point - normal boiling point) can be calculated by:

ΔT = m*Kb*i

Where m is the molal concentration (moles o solute/mass of solvent in kg), Kb is the ebullioscopy constant of the solvent, and i is the van't Hoff factor, which indicates how much of the solute dissociates. Let's assume that i is equal in both solvents and equal to 1 (the solvent dissociates completely)

Calling the new boiling point as Tb, for benzene:

Tb - 80.1 = m*2.53*1

Tb = 2.53m + 80.1

For carbon tetrachloride:

Tb - 76.8 = m*5.03*1

Tb = 5.03m + 76.8

Because Tb and m are equal for both:

5.03m + 76.8 = 2.53m + 80.1

2.5m = 3.3

m = 1.32 mol/kg

So, substituting m in any of the equations (choosing the first):

Tb = 2.53 * 1.32 + 80.1

Tb = 83.4°C
