The source of oxygen that drives the internal combustion engine in an automobile is air. Air is a mixture of gases, which are principally N2 (~79%) and O2 (~20%). In the cylinder of an automobile engine, nitrogen can react with oxygen to produce nitric oxide gas, NO. As NO is emitted from the tailpipe of the car, it can react with more oxygen to produce nitrogen dioxide gas.Write balanced chemical equations for both reactions.Express your answers as chemical equations separated by a comma. Identify all of the phases in your answer.

Explanation:

1) Reaction between nitrogen gas and oxygen gas.

[tex]N_2(g)+O_2(g)\rightarrow 2NO(g)[/tex]

According to reaction, hen 1 mole nitrogen gas reacts with 1 mole of oxygen gas it forms nitrogen oxide gas as a product.

2)reaction between  nitrogen oxide and oxygen gas.

[tex]2NO(g)+O_2(g)\rightarrow 2NO_2(g)[/tex]

According to reaction , when 2 mole of nitrogen oxide reacts with 1 moles of oxygen gas to form 2 moles of nitrogen dioxide.
