How to Balance C3H4 + Oxygen gas → Carbon dioxide + Water

How to Balance: C3H4 + O2 → CO2 + H2O

Type of Chemical Reaction: This is a combustion reaction.

Word Equation: C3H4 + Oxygen gas → Carbon dioxide + Water

Balancing Strategies: In this combustion equation C3H4 is reacting with O2 to form CO2 and H2O. It's best to balance the C and H atoms first and leave the O until last.

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.
