How to Balance Formaldehyde + Oxygen gas → Carbon dioxide + Water

How to Balance: CH2O + O2 → CO2 + H2O

Type of Chemical Reaction: This is a combustion reaction.

Word Equation: Formaldehyde + Oxygen gas → Carbon dioxide + Water

Balancing Strategies: In this combustion reaction we have CH2O and O2 gas combining to form CO2 and H2O.

Be sure to carefully count all of the O atoms on each 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.
