Chemistry / Transformation of Substances

Chemistry / Transformation of Substances

Crystals Have you noticed, changes happen everywhere around us and at all times ? All changes can be divided into two broad categories -Physical and Chemical .
Physical changes are the changes in physical properties that does not produce any new substances. These changes can be reversed like - melting of ice.
New substances are produced due to chemical changes.
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another. It is represented by a chemical equation. A complete chemical equation represents the reactants, products and their physical states symbolically. „ A chemical equation is balanced so that the numbers of atoms of each type involved in a chemical reaction are the same on the reactant and product sides of the equation. Equations must always be balanced.
In this module we'll deal more about the types of chemical reactions, oxidation and reduction.
