The video tutorial explains chemical reactions, starting with the basics of reactants and products, and the law of conservation of mass. It covers different types of reactions: synthesis, where smaller molecules form larger ones; decomposition, where larger molecules break down; replacement, where compounds swap atoms; and combustion, where oxygen breaks apart hydrocarbons to form water and carbon dioxide. Each reaction type is illustrated with examples, and the video concludes with practice problems for students.
