Exploring the Five Types of Chemical Reactions

The video tutorial explains the five main types of chemical reactions: combination, decomposition, single replacement, double replacement, and combustion. Each type is described with examples and general equations. The tutorial also highlights that some reactions can fit into more than one category and discusses the activity series of metals for single replacement reactions. The video concludes with a reminder that combustion reactions can involve hydrocarbons or other elements.
