Decomposition Reactions Overview

The video explains the decomposition reaction of MgCO3 into MgO and CO2. It describes how a single substance breaks down into two new substances, classifying it as a decomposition reaction. The video also presents the general format of such reactions, where a compound AB breaks into A and B. Dr. B concludes by summarizing the reaction process.
