${4NO}_{2} (g) + O_{2} (g) + {2H}_{2} O(l)$ $"4NO"_2("g")+"O"_2("g")+"2H"_2"O("l")$ $\to$ $rarr$ ${4HNO}_{3} (aq)$ $"4HNO"_3("aq")$

Explanation:

This is a synthesis reaction, also called a combination reaction, because two or more reactants produce a single product. You essentially have been given a word equation, which does not give the chemical formulas of each substance. In order to write a chemical equation, you need to determine the chemical formulas of each substance. Then write the equation and balance it.

Reactants
Gaseous nitrogen dioxide: ${NO}_{2} (g)$ $"NO"_2("g")$
Gaseous oxygen: $O_{2} (g)$ $"O"_2("g")$
Liquid water: $H_{2} O (l)$ $"H"_2"O"(l)"$

Product
Aqueous nitric acid: ${HNO}_{3} (aq)$ $"HNO"_3("aq")$

Balanced Equation

${4NO}_{2} (g) + O_{2} (g) + {2H}_{2} O(l)$ $"4NO"_2("g")+"O"_2("g")+"2H"_2"O("l")$ $\to$ $rarr$ ${4HNO}_{3} (aq)$ $"4HNO"_3("aq")$
