Nitrogen dioxide, a major air pollutant, can be produced by the combustion of nitrogen oxide as shown. 2NO O2 Right arrow. 2NO2
Gnesinka [82]

Nitrogen dioxide is one of the primary components of air pollution. It is released by the combustion of nitrogen oxide.

<h3 /><h3>How do you calculate the percentage yield of nitrogen oxide?</h3>

Given:

  • Mass of nitrogen oxide consumed = 1500 kg
  • Mass of nitrogen oxide produced = 1500 kg

The given chemical equation of nitrogen oxide is:

\rm 2 NO + O_2 \rightarrow 2 NO_2

Now, to calculate the percentage yield, the following conversion factor should be used:

\rm 1500\; kg \;NO \times \dfrac{1000 \;g\; NO}{1\; kg \;NO}\times\dfrac {1 \;mol \;NO}{30\; g \;NO}\times\dfrac {2 \;mol \;NO_2}{2 \;mol \;NO}\times\dfrac {46 \;g \;NO_2}{1 \;mol \;NO_2}\times\dfrac {1 \;kg}{1000 \;g}

Nitrogen dioxide = 2300 kg

The percentage yield will be:

\rm Percentage Yield = \dfrac{Actual \; Yield}{Expected \;Yield}\times 100\\\\\\&#10;\rm Percentage Yield = \dfrac{2500\;kg}{2300\;kg}\times 100\\

Percentage yield = 65.2 %

Thus, the percentage yield of nitrogen dioxide is 65.2%.

WORTH 20 POINTS! MY LIFE DEPENDS ON IT HELP
igor_vitrenko [27]

Answer:

2

Explanation:

Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.
