The video tutorial covers combustion and oxidation reactions, focusing on how to determine the amount of fuel combusted with air. It introduces a simplified reaction equation, discusses theoretical combustion, and performs a mass balance for carbon, hydrogen, oxygen, and nitrogen. The tutorial uses methane as an example to illustrate the process, balancing the components to derive the final reaction equation.
