How to Balance:

NO + O2 → NO2

Word equation: Nitrogon monoxide + Oxygen gas → Nitrogen dioxide

Type of Chemical Reaction: For this reaction we have a combination reaction.

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.

For a complete explanation, watch:

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.
