Concept Introduction:
In a balanced chemical equation, all the constituents present in the reaction have equal number of atoms on both side of the reaction arrow.

Answer to Problem 5.119P
Explanation of Solution
Decommission of solid Ammonium Nitrate generates gaseous dinitrogen oxide along with the water vapour.
The balanced chemical equation of the reaction taking place is as depicted below:
From the above balanced reaction, for each mole of NH4 NO3 produces one mole of di-nitrogen oxide and 2 moles of water.
(b)

Answer to Problem 5.119P
Partial pressure of
Explanation of Solution
Calculate the number of moles of
Therefore, number of moles of
Calculate the number of moles of water is as follows:
Therefore, number of moles of water is 0.0624 mol H2 O.
From the ideal equation we have.
To calculate the partial pressure of
Therefore, the partial pressure of
Volume of tank v = 1.75 L.
Number of moles of water n = 0.0624 moles.
The temperature t = 503 K.
To calculate the partial pressure of water, substitute all the known value in the equation.
Therefore, partial pressure of water is 1.47 atm.
(c)
Interpretation:
The total gas pressure present in the flask at 2300 C should be determined.
Concept Introduction:
Dalton's law of partial pressure is state that the total pressure of a mixture gases is sum of the pressures that every gas would exert if it were present alone.

Answer to Problem 5.119P
Total pressure present in flask is 2.21 atm.
Explanation of Solution
In the provided reaction the gases molecules are
Therefore, total pressure present in flask is 2.21 atm.
(d)
Interpretation:
The three equivalent resonance structure for
Concept Introduction:
The resonance structures show the arrangement of electrons and bonds in a molecule. The lone pair present on atom can show delocalization with pi electrons of double or triple bonds resulting formation of resonance structures. The position of atoms remains the same only position of bonds changes.

Answer to Problem 5.119P
Explanation of Solution
The resonance structures of N2 O is shown in the following diagram.
Since, nitrogen has 3 valence electrons it can form three covalent bonds with other atoms. There are two valence electrons in oxygen thus, it can form one double or two single bonds with other atoms. Being more electronegative in nature, oxygen atom will be placed at the terminal position. Thus, there will be one double bond between two nitrogen atom and one double bond between nitrogen and oxygen atom resulting negative charge on one nitrogen atom and positive charge on other nitrogen atom.
The negative charge can delocalize with pi electrons of double bond resulting two resonance forms.
