If 5.2 moles of oxygen react, how many moles of nitrogen monoxide are produced? Round to the nearest tenth, include units on your answer.

10.4 moles

Explanation:

Given parameters:

Number of moles of oxygen = 5.2moles

Number of moles of nitrogen monoxide = ?

Solution:

To solve this problem, we need to work from the known to the unknown specie according to the reaction.

Oxygen gas is known and we can estimate the amount of mole of nitrogen monoxide;

Let us write the balanced reaction equation;

                N₂    +      O₂          →          2NO

  according to this reaction;

       1 mole of oxygen gas will produce 2 mole of NO

       5.2 moles of oxygen gas will produce  (5.2 x 2)moles  = 10.4moles

10.4 moles

Explanation:

The equation of the reaction between oxygen and nitrogen to produce nitrogen monoxide is,

N₂(g) + O₂ (g)→ 2NO (g)

1        :   1         :   2

This mean 1 mole of nitrogen gas react with 1 mole of oxygen gas to give 2 moles of nitrogen monoxide

In this case the if 5.2 moles of Oxygen react, it will give 2 moles of NO

5.2*2=10.4

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
