Answer: The equation is written below.
Explanation:
For the formation of nitrogen dioxide, the reactants used are nitrogen monoxide and oxygen gas.
The balanced chemical equation for the above reaction is given as:
[tex]2NO(g)+O_2(g)\rightarrow 2NO_2(g)[/tex]
By Stoichiometry of the reaction:
2 moles of nitrogen monoxide gas reacts with 1 mole of oxygen gas to produce 2 moles of nitrogen dioxide gas.
