Chemical Reaction and Equations
Chemical Equations and Reactions – A Detailed Guide for Class 10 CBSE Introduction Chemical reactions are the foundation of chemistry, enabling the transformation of substances. A chemical equation is a symbolic representation of a chemical reaction, showing the reactants and products. 1. Chemical Reactions A chemical reaction is a process in which one or more substances ( reactants ) undergo a transformation to form new substances ( products ). The reaction is usually accompanied by changes such as: Change in state (solid, liquid, gas formation) Change in color (e.g., rusting of iron) Evolution of gas (e.g., reaction of acids with metals) Change in temperature (exothermic and endothermic reactions) 2. Chemical Equations A chemical equation represents a chemical reaction using symbols and formulas of the reactants and products. Balanced Chemical Equations A balanced equation has equal numbers of atoms of each...
