A compound is formed by the reaction of nitrogen with oxygen gas. Can you predict the formula of the compound formed? Explain.
1 answer:
Nitrogen Oxides (or Oxides of Nitrogen) are a mixture of gases that are formed by the reaction of nitrogen and oxygen.
Some of these Oxides of Nitrogen to name are:
Nitric Oxide ()
Nitrogen Dioxide ()
Nitrogen Monoxide ()
Nitrogen Pentoxide ()
Nitrogen dioxide is mainly formed for the manufacture of nitric acid, most of which is further used in the manufacture of fertilisers, while some is used in the production of explosives for mining and military purposes.

Answer:
6,97x10⁻³ gallons
Explanation:
pH is defined as:
pH = -log [H⁺]
Thus, you need to have, in the end:
10⁻⁷ = [H⁺]
And you have, in the first:
= [H⁺]
The volume of swimming pool is:
700'000 galllons × = 2649787 L
Thus, the moles of H⁺ in the first and in the end are:
First:
× 2649787L = 1,24x10⁻³ moles
End:
× 2649787L = 0,265 moles
Thus, the moles of H⁺ you need to add are:
0,265 - 1,24x10⁻³ = <em>0,26376 moles</em>
These moles comes from 10M HCl, thus, the volume in gallons you need to add are:
=
<em>6,97x10⁻³ gallons</em>
<em></em>
