Chapter 9, Problem 9.121CHP

(a)

Interpretation Introduction

Interpretation:

The balanced equation for the decomposition reaction has to be written.

Concept Introduction:

Balancing equations:

In a reaction, the number of molecules before and after the reaction should be equal. That means the number of moles of particular compound on either side of the reaction should be equal, this can be done by multiplication with the number of molecules required to make them equal in a reaction.

(b)

Interpretation Introduction

Interpretation:

The total pressure and partial pressure of $\text{Xenon}\text{and}\text{Oxygen}$ in the container has to be calculated.

Concept Introduction:

Ideal gas equation is an equation that is describing the state of an imaginary ideal gas.

$\text{PV}\text{=}\text{n RT}$

Where,

P is the pressure of the gas

V is the volume

n is the number of moles of gas

R is the universal gas constant $\text{(R=0}{\text{.0821LatmK}}^{\text{-1}}{\text{mol}}^{\text{-1}})$

T is the temperature

Number of moles:

It is a physical property, which is defined as the mass of a given substance divided by the amount of substance. Unit of the mole is $\text{mol}$

$\text{number}\text{of}\text{moles}\text{=}\text{amount}\text{of}\text{mass}\text{×}\frac{\text{1}\text{mol}}{\text{molar}\text{mass}}$
