swing by trial and error

this is a method used to balance chemical equations and make them balanced

1. write your reagent (we will use the
C3H8 + O2 -> H2O + CO2 as example)

C3H8 + O2 => H2O + CO2

2. Locate the elements that are presented in the equation

C3H8 + O2 => H2O + CO2
Carbon
Hydrogen
Oxygen

3. List the elements trying to leave the hydrogen in place and the oxygen at the end.

C3H8 + O2 => H2O + CO2
C
H
O

4. Count the number of atoms in each equation and write them down

C3H8 + O2 => H2O + CO2
                 3C3
                 8H2
                 2O3

5. add coefficients to equations to equalize

C3H8 + 5O2 => 4H2O + 3CO3

3C3

8H8

10O10
