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.

Answer:
1.30 m
Explanation:
First we <u>calculate the number of moles of solute in the solution</u>, using the <em>definition of molarity</em>:
- Molarity = moles / liters
- Converting 250 mL ⇒ 250 / 1000 = 0.250 L
- moles = 1.50 M * 0.250 L = 0.375 moles
Then we <u>calculate the mass of solvent</u>, using the <em>given volume and density</em>:
- 1.15 g/mL * 250 mL = 287.5 g
- Converting <em>287.5 g to kg</em> ⇒ 287.5 / 1000 = 0.2875 kg
Now we <u>calculate the molality of the solution</u>:
- molality = moles of solute / kg of solvent = 0.375 mol / 0.2875 kg
Nobody specifically made the periodic table but it was first thought of by Dmitri Mendeleev in 1869.
