<span>The water cycle has no starting point. But, we'll begin in the oceans, since that is where most of Earth's water exists</span>

The water cycle begins in evaporation. For example, the suns heat causes water to evaporate and the water cycle goes on.

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:

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

Percentage yield = 65.2 %

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