The video tutorial explains the basic chemical reaction involved in barbecuing, where oxygen from the air and carbon from charcoal combine to form carbon dioxide. The process is described with the chemical formula CO2, highlighting the presence of dioxygen in the air and carbon in charcoal. The video concludes with a thank you note.
