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 Lose weight . 1.
