Chemical Reactions and Their Types

The video explains the reaction between sodium bicarbonate (NaHCO3) and hydrochloric acid (HCl). Initially, it appears to be a double displacement reaction, forming sodium chloride and carbonic acid. The carbonic acid then decomposes into carbon dioxide and water, illustrating a decomposition reaction. The video clarifies the two-step process and identifies the types of reactions involved.
