Well a molecule of water is equal to 1 Oxygen and 2 Hydrogen each, so it'd be 2 molecules of water

Answer: Option (b) is the correct answer.

Explanation:

$2H_{2} + O_{2} \rightarrow 2H_{2}O$

As it can be seen from the chemical equation, 2 moles of hydrogen reacts with 1 mole of oxygen.

Therefore, 2 moles of oxygen will react with 4 moles of hydrogen. So, oxygen is the limiting reagent and hydrogen is the excess reagent. Therefore, the reaction equation will be as follows.

$4H_{2} + 2O_{2} \rightarrow 4H_{2}O$

Thus, we can conclude that 4 moles of water are produced when 5 moles of hydrogen gas react with 2 moles of oxygen gas.

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:
