A gas that exerts a pressure of
spayn [35]

Answer:

3.089 L

Explanation:

From the given information, provided that the no of moles and the temperature remains constant;

P_1 = 15.6 psi

V_1 = ???

P_2 = 25.43 psi

V_2 = 1.895 L

Using Boyle's law:

P_1V_1 =P_2V_2 \\ \\ V_1 = \dfrac{P_2V_2}{P_1} \\ \\  V_1 = \dfrac{25.43 \times 1.895}{15.6}  \\ \\ \mathbf{  V_1 = 3.089  \ L}

Answer:

Which of the following

properties distinguishes a solution

oversaturated with a dilute?

  • The supersaturated solution is one in which the solvent has dissolved more solute than it can dissolve in the saturation equilibrium.  The solute can be a solid, or a gas. The molecules of the solvent surround those of the solute and seek to open space between themselves to be able to harbor more amount of solute.
  • A dilute solution is a solution that has not reached the maximum concentration of solute dissolved in a solvent. The additional solute will dissolve when added in a dilute solution and will not appear in the aqueous phase.   It is considered a state of dynamic equilibrium where the speeds in which the solvent dissolves the solute are greater than the recrystallization rate.
