Question of Class 10-Chemical Equations : Chemical Equations: The short-hand method of representing a chemical reaction in terms of symbols and formulae of the different reactants and products is called a chemical equation. A chemical reaction is described by a chemical equation that gives the identities and quantities of the reactants and the products. In a chemical reaction, one or more substances are transformed to … A chemical equation or chemistry notation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas. On this page of our Chemistry Tutorial, learn how to represent chemical reactions symbolically using formulas, coefficients, and state symbols—and discover how to count atoms to ensure your equations are balanced, reflecting the law of conservation of mass. Managing your way through a Chemistry course can be difficult.
