How to Balance Nitrogon monoxide + Oxygen gas → Nitrogen dioxide

How to Balance: NO + O2 → NO2

Type of Chemical Reaction: This is a combination reaction.

Word Equation: Nitrogon monoxide + Oxygen gas → Nitrogen dioxide

Balancing Strategies: In this combination (also called synthesis) reaction, the NO and O2 are combining to form NO2.

Be sure to count all of the Oxygen atoms on the reactant side of the equation.

About Balancing Chemical Equations

When balancing chemical equations our goal is to have the same number of each type of atom on both sides of the equation.

Only change the coefficients (these are the numbers in front substances).
Coefficients are the numbers in front of the molecule.
Never change the subscripts (the small numbers after elements).
Coefficients are the numbers in front of the molecule.
