Acid rain can be destructive to both the natural environment and human-made structures. The equation below shows a reaction that occurs that may lead to the formation of acid rain.
                            3NO2 + H2O  2HNO3 + NO

How many moles (precise to the nearest 0.01 mol) of nitric acid are produced from 300.00 mol of nitrogen dioxide?

200.00 mol
200.09 mol
450.00 mol
450.02 mol

Balanced chemical equation

3 NO2 + H2O = 2 HNO3 + NO

3 mol NO2 --------> 2 mol HNO3
300.00 NO2 --------> x mol HNO3

3 * x = 300.00 * 2

3 x = 600.00

x = 600.00 / 3

x = 200.00 mol

hope this helps!.

Answer : The correct option is, 200.00 mole

Explanation : Given,

Moles of nitrogen dioxide = 300.00 mole

The balanced chemical reaction will be,

[tex]3NO_2+H_2O\rightarrow 2HNO_3+NO[/tex]

From the balanced chemical reaction, we conclude that 3 moles of nitrogen dioxide react with 1 mole of water to give 2 moles of nitric acid and 1 mole of nitric oxide as a product.

As, 3 moles of nitrogen dioxide react to give 2 moles of nitric acid

So, 300.00 moles of nitrogen dioxide react to give [tex]\frac{2}{3}\times 300.00=200.00[/tex] moles of nitric acid

Therefore, the number of moles of nitric acid is, 200.00 moles
