In your opinion, what would be the simplest way to balance any size of the chemical equation?
For example here is an equation: $$\ce{C12H26 + O2 -> CO2 + H2O}$$
I saw some ways by putting letters in front of each molecule, but I just don't get too much how to do this with this method! My teacher is always speaking about another method, but it simply doesn't feel logic/mathematics is enough for me.
