Octane and Oxygen
2C8H18+25O2 -> 16CO2+18H2O
Octane + Oxygen yields to Carbon Dioxide + Dihydrogenoxide
A combustion type of reaction
This reaction is used to produce gasoline, a transparent petroleum-derived liquid that is used primarily as fuel for engines.
Step 1: Write a balanced equation for the reaction.
Balance the equation by looking at each element seperatly and what amount of atoms the have, ONLY CHANGE COEFFICIENTS DON'T CHANGE SUBSCRIPTS! put a coefficient in front of each compound until each separate element is even with its counter element on the other side of the equation
A stands for given
B stands for what you are trying to find out
Step 3: Convert mass of reactant to moles of reactant.
Step 4: Put coefficients of A (lower) and B (upper) into third columns
