A chemical reaction is a reaction in which reactants reacts and form new compound or a subtances in a chemical reaction is called chemical reaction Types of chemical reaction. +Combination reaction. +Decomposition reaction +Displacement reaction. +Double Displacement Reaction. +Redox reaction

A chemical reaction is in which the bonds are broken within reactant molecules, and new bonds are formed within product molecules in order to form a new substance. Two examples are:- #hydrogen + oxygen ---> water #iron + oxygen ---> rust Types of reactions are as follows:- 1. Combination Reaction A reaction in which two or more reactants combine to form a single product is known as a combination reaction.It takes the form of X + Y → XYCombination reaction is also known as a synthesis reaction.Example of combination reaction: 2Na + Cl2 → 2NaCl 2. Decomposition Reaction A reaction in which a single compound breaks into two or more simpler compounds is known as a decomposition reaction.It takes the form of XY → X + YA decomposition reaction is just the opposite of combination reaction.Example of a decomposition reaction: CaCO3 → CaO + CO2The reaction in which a compound decomposes due to heating is known as a thermal decomposition reaction. 3. Displacement Reaction A chemical reaction in which a more reactive element displaces a less reactive element from its aqueous salt solution.It takes the form X + YZ → XZ + YIt is also called a substitution reactionExample of displacement reaction: Zn + CuSO4 → ZnSO4 + Cu 4. Double Displacement Reaction A chemical reaction in which ions gets exchanged between two reactants which form a new compound is called a double displacement reaction.It takes the form of XY + ZA → XZ + YAIt is also called a metathesis reactionExample of double displacement reaction:             BBaCl2 + Na2SO4 → BaSO4 + 2NaCl 5. Precipitation Reaction A chemical reaction that involves the formation of an insoluble product (precipitate; solid) is called Precipitation reaction.The reactants are soluble, but the product formed would be insoluble and separates out as a solid.The chemical equation by which a chemical change is described is adequate for reaction in solutions, but for reactions of ionic compounds in aqueous solution (water), the typical molecular equation has different representations.A molecular equation may indicate formulas of reactants and products that are not present and eliminate completely the formulas of the ions that are the real reactants and products.If the substance in the molecular equation that is actually present as dissociated ions are written in the form of their ions, the result is an ionic equation.
