Chemistry
1 answer:
PtichkaEL [24]2 years ago
5 0

Answer:

"Your Choice: Liberation From Your Own Choices or Continue the Choice That Decreases Your Liberation."

Explanation:

Liberation is the freeing or release from something restraining you. In this case, smoking holds you back from doing the things you used to do.

It's not that creative, but I hope this is good enough for you! :D (don't smoke)

14. a. Acidic

15. b. Weaker

16. d. Dilute and weak

Explanation:

14. Which type of the solution is one with the pH of 3?

Solution with pH from 1 to 7 are acidic, equal to 7 is neutral and from 7 to 14 basic. The solution with the pH equal to 3 is <u>acidic</u>.

15. The smaller the value of the base dissociation constant (Kb), the <u>weaker</u> the base.

The dissociation reaction of a base (B) is:

B + H₂O → BH⁺ + OH⁻

Kb is defined as:

Kb = ( [BH⁺] × [OH⁻] ) / ( [B] × [H₂O] )

The potency of the base depends on the concentration of the hydroxide ion [OH⁻], so if the Kb ratio is small it means that the concentration of hydroxide ion is smaller so the base will be <u>weaker</u>.

16. A 0.39 M solution of an acid that ionizes only slightly in solution would be termed <u>dilute and weak</u>.

The acid is weak because is only slightly ionizing in solution. The therm diluted is a little bit arbitrarily because we ask yourself "diluted in respect with what"? I would characterize the acid to be diluted at a concentration of 1 M and concentrated at a concentration of 10 M.

Which response includes all of the following processes that are accompanied by an increase in entropy?
dlinn [17]

Answer:

1 and 3.

Explanation:

The entropy measures the randomness of the system, as higher is it, as higher is the entropy. The randomness is associated with the movement and the arrangement of the molecules. Thus, if the molecules are moving faster and are more disorganized, the randomness is greater.

So, the entropy (S) of the phases increases by:

S solid < S liquid < S gases.

1. The substance is going from solid to gas, thus the entropy is increasing.

2. The substance is going from a disorganized way (the molecules of I are disorganized) to an organized way (the molecules join together to form I2), thus the entropy is decreasing.

3. The molecules go from an organized way (the atom are joined together) to a disorganized way, thus the entropy increases.

4. The ions are disorganized and react to form a more organized molecule, thus the entropy decreases.
