The answer is c, because we use it as an "index" to tell when the animal lived, so if it's unique to that time level in the ground we know it lived that long ago.

At a pressure of 1.00 atm, the solubility of nitrogen in water is 23.5 mg gas/100 g water. Indicate whether each of the followin
marysya [2.9K]

Answer:

a) Solubility diminishes.

b) Solubility remains constant.

c) Solubility increases.

d) Solubility increases.

Explanation:

Hello,

a) In this case, we've got to take into account that the solubility of a gas into a liquid increases as the pressure does it (because the molecules are forced to gather with the liquid's particles) and the other way around, in such a way, as the pressure is decreased, the solubility is decreased as well.

b) Well, the outer space is related with the atmospheric pressure as long as the column of air is what is exerting the pressure, thus, as this pressure is quantified as 1 atm, there won't be any appreciable change in the solubility as the pressure remains the same.

c) Now, as the pressure is increased, the solubility is increased in a very similar way that in the a) part.

d) Submerging the solution 40m underwater means that the fluid's column above the solution is increased, thus, the pressure is increased, so the solubility is increased as well.

Best regards.
