N2+NO2=

The reaction between nitrogen (N₂) and nitrogen dioxide (NO₂) typically leads to the formation of dinitrogen tetroxide (N₂O₄). The balanced chemical equation for this reaction can be written as:

\[ N_2 + 2 NO_2 \rightarrow N_2O_4 \]

This equation indicates that one molecule of nitrogen reacts with two molecules of nitrogen dioxide to form one molecule of dinitrogen tetroxide.
