Air-bags can be inflated by the decomposition of sodium azide, NaN3. At 25.0◦C and 1.10 atm, what volume of N2(g) is produced by

Mashcka [7]

Answer:

V = 36.7L of $N_{2}$

Explanation:

1. Write the chemical reaction for the decomposition of sodium azide:

$_{2}NaN_{3}(l)=_{2}Na(s)+_{3}N_{2}(g)$

2. Find the number of moles of $N_{2}$ produced by the decomposition of 71.4g of $NaN_{3}$ :

$71.4gNaN_{3}*\frac{1molNaN_{3}}{65gNaN_{3}}*\frac{3molesN_{2}}{2molesNaN_{3}}=1.65molesN_{2}$

3. Use the ideal gas equation to find the Volume of $N_{2}$ occupied by 1.65 moles of $N_{2}$ , at the temperature and pressure given by the problem:

$PV=nRT$

Solving for V:

$V=\frac{nRT}{P}$

Converting the temperature from ◦C to K:

25◦C+273.15=298.15K

Replacing values:

$V=\frac{1.65mol*(0.082\frac{atm.L}{mol.K})*298.15K}{1.10atm}$

V=36.7L of $N_{2}$

Explanation:

During the formation of BeCl2, the beryllium atom bonds with two chlorine atoms via single covalent bonds. The number of electron pairs around the central atom will be two. No lone pair is found in the molecule. If we analyse this information then we can conclude that BeCl2 has sp hybridization.
