Combustion Reactions and Products

The video tutorial explains combustion reactions, focusing on the burning of hydrocarbons in the presence of oxygen. It distinguishes between complete and incomplete combustion, highlighting the differences in oxygen supply and resulting products. Examples using methane demonstrate how to write and balance chemical equations for both types of combustion. The tutorial emphasizes the importance of balancing equations, especially for incomplete combustion, due to the presence of toxic byproducts.

What is always a reactant in combustion reactions?

• Carbon
