The video tutorial explains how to predict the products of a reaction between hydrogen (H2) and oxygen (O2). It suggests that the most likely product is water (H2O) due to the exothermic nature of the reaction. The possibility of forming hydrogen peroxide (H2O2) is mentioned but deemed unlikely due to its instability. The tutorial concludes with balancing the chemical equation for the reaction.
