15. An apparatus consists of a 4.0 dm3
Solnce55 [7]

Answer:

i· Partial pressure of nitrogen gas is 219.429kPa and partial pressure of argon gas is 33.714kPa ·

ii· Total pressure of the gas mixture is 253.143kPa·

Explanation:

<h3>solution for i :</h3>

Assuming that the given gases to be ideal,

so by ideal gas equation

PV=nRT

where,

P is the pressure of the gas

V is the volume occupied by the gas

n is the number of moles of the gas

R is the ideal gas constant

T is the temperature of the gas

Actually partial pressure of each gas is the pressure of the gas exerted when it occupies complete volume

As the temperature of both gases are same, the mixing process  is an isothermal process

PV=constant

Initially for nitrogen gas PV=803×4=3212

let Px_{1} be the partial pressure of the nitrogen gas

(Px_{1})×14=3212

∴Px_{1}=219.429kPa

∴Partial pressure of nitrogen gas is 219.429kPa

Initially for argon gas PV=47.2×10=472

let Px_{2} be the partial pressure of the argon gas

(Px_{2})×14=472

∴Px_{2}=33.714kPa

∴Partial pressure of argon gas is 33.714kPa

solution for ii :

Total pressure of the gas mixture will be the sum of the partial pressures of each gas as

Partial pressure of the gas=(total pressure of the mixture)×(mole fraction of the gas)

∴Total pressure=Px_{1}+Px_{2}

                          =219.429+33.719

Total pressure    =253.143kPa

A sample of a solid labeled as NaCl may be impure. a student analyzes the sample and determines that it contains 75 percent chlo
Evgesh-ka [11]

Answer:

D

Explanation:

The sample must contain impurity that is lower in atomic mass to sodium and since potassium has higher atomic mass to sodium, the answer is the sample contains NaCl and LiCl. We are sure already that the sample is not pure which rules out  option a and option b contains sodium iodide which cannot contribute to the increase in chlorine
