Chemical Reaction: A process in which two or more substances react to form some other new substances with a new set of properties is called a chemical reaction.

 

A chemical bond is an attractive force which holds the atoms of a molecule together in a compound.

 

Chemical reactions are represented by chemical equations.

 

Substances taking part in a reaction are called reactants, and the new substances formed are called products.

 

Chemical reaction: Reactants → Products

 

Example: Sodium hydroxide reacts with dilute hydrochloric acid to form salt and water.

stack space space 2 NaOH with sodium space space hydroxide below space space plus space space space space space stack HCl space with hydrochloric space space acid below space space space space space space rightwards arrow space space space stack space NaCl with sodium space space chloride below space space space plus space space stack straight H subscript 2 straight O with space water below
 
 
Sodium hydroxide and hydrochloric acid are reactants, and sodium chloride and water are products.
