A. P1, V1, T1, P2, and V2: 3.5 atm, 3.2 L, 323 K, 1.5 atm, and 2.6 L, respectively

B. The problem is asking you to determine T2, the temperature of the gas based on the conditions above

C. Since pressure, volume, and temperature are all changing and are all interrelated, the combined gas law is best for this problem:

P1 • V1 P2 • V2
———— = ————
T1 T2

D. Substituting in all of the values above:

(3.5)(3.2) (1.5)(2.6)
————— = —————
(323) T2

(11.2) (3.9)
——— = ———
(323) T2

(3.9)
0.03467 = ———
T2

(3.9)
T2 = ————— = 112.49 K
0.03467

The second temperature under these conditions would be about 112.49 K.

Hope this helps!

hat is the best way to compare a concentrated solution to a dilute solution, given the same volume of solution?
xxMikexx [17]

Answer:

Using the molarity of the solution

Explanation:

The concentration of the two solutions can be compared by the use of the number of moles of solute present in each of the solutions. The solution with a higher molarity will be concentrated while the solution with a lower molarity will be dilute.

Ali says the climate of a town is rainy because it is raining outside today. Is she correct? In one or two sentences, explain wh
Umnica [9.8K]

Answer:

Ali is incorrect.

Explanation:

Ali is wrong because the climate is a study of the weather pattern over a long period of time. You cannot look outside one day and determine the climate because the climate is long-term.

She could say the weather is rainy, because that is short term, but not the climate.
