To do so let's multiply all coefficients by two: Right now there are same numbers of atoms on both sides of the equation - but to finish balancing we have to remove the fraction.
Remember, we can use fractions at this stage: Two are already present in the ethylene glycol, so we need five more - 2 1/2 oxygen molecule will do. To balance equation thus we need seven oxygen atoms on the left. There are seven atoms of oxygen on the right - four in molecules of carbon dioxide and three in water molecules. There are two atoms of carbon in ethylene glycol molecule, so let's add 2 in front of CO2.Ĭarbon is balanced, what about hydrogen? There are six hydrogen atoms on the left side of the reaction, so we need three water molecules on the right to balance hydrogen: Let's start balancing with carbon and hydrogen. Technically speaking if there is no coefficient, it means there is only one molecule of the compound, but we will put ones into the equations now to differentiate between molecules we have already tried to balance, and those that are not touched yet.īoth carbon and hydrogen are present in two molecules, oxygen is present in all four molecules. The most complicated molecule is that of ethylene glycol, so let's put 1 in front of it. Let's try with ethylene glycol combustion:
Start with the most complicated compound.
