Types of chemical reaction
Chemical reactions can be grouped into different types based on how substances change. The main types are combination, decomposition, single displacement, double displacement, and combustion reactions. In a combination reaction, two or more substances join to form one new substance. In a decomposition reaction, one compound breaks down into simpler substances. In a single displacement reaction, one element replaces another in a compound. In a double displacement reaction, two compounds exchange ions to form new compounds. In a combustion reaction, a substance reacts with oxygen, releasing heat and light. Understanding these types helps us explain many chemical changes that happen in nature, industries, and everyday life.
