Identify 3 characteristics that would be taken into consideration when evaluating any proposed site for a national repository of

nuclear waste.
Chemistry
1 answer:
Mashutka [201]3 years ago
7 0

Answer:

  • Proximity to water bed/water source
  • Geographical isolation and barriers
  • unavailability of plant or any biosystem

Explanation:

A nuclear repository would be required to be isolated with barriers in place to keep people out. Ideally, it should be stored underground and away from any underlying waterways, or biosystems so as to avoid contamination. A good example would be the proposed Yucca Mountain repository.

I hope this was helpful and useful.

Which of the following actions would cause the volume of the chamber below to increase to 36.0 L?
Orlov [11]

Answer:

Option C. Triple the number of moles

Explanation:

From the ideal gas equation:

PV = nRT

Where:

P is the pressure

V is the volume

n is the number of mole

R is the gas constant

T is the absolute temperature.

Making V the subject of the above equation, we have:

PV = nRT

Divide both side by P

V = nRT / P

Thus, we can say that the volume (V) is directly proportional to both the number of mole (n) and absolute temperature (T) and inversely proportional to the pressure (P). This implies that and increase in either the number of mole, the absolute temperature and a decrease in the presence will cause the volume to increase.

Thus, the correct option is option C triple the number of moles. This can further be seen as illustrated below:

Initial volume (V1) = 12 L

Initial mole (n1) = 0.5 mole

Final mole (n2) = triple the initial mole = 3 × 0.5 = 1.5 mole

Final volume (V2) =?

From:

V = nRT / P, keeping T and P constant, we have:

V1/n1 = V2/n2

12/0.5 = V2/1.5

24 = V2/1.5

Cross multiply

V2 = 24 × 1.5

V2 = 36 L.

Thus Option C gives the correct answer to the question.
