Answer:-
(a) 3.5
(b) 3
Explanation:-
2KClO3 --> 2KCl + 3 O2
From the equation we see that 2 moles of KClO3 gives 2 moles of KCl.
So 3.5 moles of KClO3 will give 3 moles of KCl.
Again
3 moles of O2 are produced with 2 moles of KCl.
If 4.5 moles of O2 produced then
moles of KCl = 4.5 x 2/3
=3

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
I believe the correct answer would be the last option. All of the quantities given above contain the same number of particles. We determine this by using the avogadro's number. It represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole.
2 moles of carbon atoms ( 6.022 x 10^23 particles / mole ) = 1.20 x10^24 particles
<span>
2 moles of carbon dioxide molecules </span>( 6.022 x 10^23 particles / mole ) = 1.20 x10^24 particles<span>
2 moles of diatomic oxygen molecules </span>( 6.022 x 10^23 particles / mole ) = 1.20 x10^24 particles
As you can see, no matter what is the gas as long as they have the same number of moles, they would also have same number of particles<span />
