Question

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  + H

2 O   2HNO 3  + 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

Answer 1

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 2

Answer : The correct option is, 200.00 mole

Explanation : Given,

Moles of nitrogen dioxide = 300.00 mole

The balanced chemical reaction will be,

`3NO_2+H_2O\rightarrow 2HNO_3+NO`

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
`(2)/(3)* 300.00=200.00` moles of nitric acid

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