Physical Changes of Matter

A physical change occurs when a substance changes but no new substance is formed. The chemical composition remains the same. Examples: Crushing of bottles, cutting of paper, etc.

Chemical Changes of Matter

A chemical change occurs when a new substance is formed. It can be identified by:

  • Change in colour
  • Production of gas
  • Change in temperature.
  • Change in state

Chemical Equation

It is the equation used to represent a chemical reaction. It has reactants in the left and product in the right of the direction sign.

For example: Mg + O2 = MgO2

1. Combination Reaction: In this reaction, a single product is formed from
two or more reactants.
Examples: The reaction of quick lime with water to produce slaked lime is a
combination reaction.

2. Decomposition Reaction: The reaction in which a single reactant breaks
down to give simpler products are called decomposition reaction.

Examples: The reaction of ferrous sulphate to give ferric oxide, sulphur dioxide, and sulphur trioxide is an example of a decomposition reaction.

3. Displacement Reaction: In this reaction, the most reactive elements
replace the less reactive elements.

4. Double Displacement Reaction: In this, two compounds react to form
different compounds. This occurs by mutual exchange of ions or atoms.

Examples: The reaction of sodium sulphate and barium chloride is an example of
displacement reaction.
