How will the solubility of a gas solute change if the pressure above the solution is reduced?

the limit of the gas's solubility will fluctuate.
the limit of the gas's solubility will stay the same.
the limit of the gas's solubility will decrease.
the limit of the gas's solubility will increase.

The limit of the gas's solubility will decrease.

Explanation:

The solubility of a gas in a liquid is explained by Henry's law.

S = k . P

where,

S is the solubility of the gas

k is the Henry's constant (depends on each gas)

P is the partial pressure of the gas (at equilibrium with the pressure above the solution)

We can see that the solubility is directly proportional to the pressure. If the pressure is reduced, the solubility decreases.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
