Chapter 13 Chemical Mixtures: Solutions and Other Mixtures

Question 1

Solubility

Answer 1

a quantitative measure of the amount of solute that will dissolve in a solvent at a given temperature (solute/solvent)

Question 2

Is mixing gases entropy favored or entropy disfavored?

Answer 2

mixing gases is entropy favored because it increases the disorder of the system

Question 3

Does enthalpy play a role in gas mixing?

Answer 3

no, because gases have no appreciable IMFs, therefore, all gases are expected to mix in all proportions and the process is favored at any temperature

Question 4

What is one thing that can prevent the mixing of gases?

Answer 4

when a chemical reaction occurs between gases that result in a solid molecule

Question 5

Are hydrocarbons polar or nonpolar?

Answer 5

all hydrocarbons are nonpolar molecules
