A decrease in pressure has the greatest effect on a solution that contains.. ?
Naddika [18.5K]
<h3><u>Answer;</u></h3>

A gas in a liquid

<h3><u>Explanation;</u></h3>
  • Pressure affects the solubility of gases. According to Henry's law, the solubility of a gas in a liquid is proportional to the partial pressure of the gas above the liquid at a given temperature,
  • Therefore; For the solubility of gases in liquids, as pressure increases, solubility increases. Hence pressure will have a effect on a solution with a gas in liquid.

Which of the following will increase solubility the rate of the dissolving process of a gaseous solute in solvent? (mark all tha
Pepsi [2]

Answer: The increase in solubility or the rate of dissolving process of a gaseous solute in a liquid solvent is due to following:

  • Increasing agitation
  • Increasing temperature
  • Increasing solute's partial pressure over the solvent
  • Increasing solute's surface area

Explanation:

When agitation is increased then there will occur an increase in kinetic energy of the molecules of a substance. As a result, more number of collisions will take place due to which more amount of solute will dissolve into the solvent.

Similarly, increasing the temperature will further increase the kinetic energy of molecules. Hence, this will lead to more solubility of gaseous solute into the liquid solvent.

As solubility of a gas is directly proportional to the pressure of the gas above surface of the solution. So, an increase in solute's partial pressure over solvent will also lead to an increase in solubility of gaseous solute into liquid solvent.

When surface area of solute is increased then there will be more solute particles available for reaction. Hence, more collisions will take place. As a result, rate of reaction is more due to which there will be an increase in solubility.

Thus, we can conclude that the increase in solubility or the rate of dissolving process of a gaseous solute in a liquid solvent is due to following:

  • Increasing agitation
  • Increasing temperature
  • Increasing solute's partial pressure over the solvent
  • Increasing solute's surface area

What is redox reaction??<br><img src="https://tex.z-dn.net/?f=%20%5C%5C%20%20%5C%5C%20" id="TexFormula1" title=" \\ \\ " alt="
MAXImum [283]

Answer:

Oxidation–reduction or redox reactions are reactions that involve the transfer of electrons between chemical species (check out this article on redox reactions if you want a refresher!). The equations for oxidation-reduction reactions must be balanced for both mass and charge, which can make them challenging to balance by inspection alone. In this article, we’ll learn about the half-reaction method of balancing, a helpful procedure for balancing the equations of redox reactions occurring in aqueous solution.
