CHEMICAL REACTION

We know, the chemical reaction is process involve transformation of substance to form another substances.

Initial substances involved in reaction called REACTANT or REAGENTS
Final substances produce after reaction happened called PRODUCTS

# Example of reaction students learn in Chemistry is

i) Neutralisation : Reaction between Acid and Alkali.
ii) Displacement of Metal : Reaction of Electropositive metals and Salts Solution.
iii) Combustion : Burn the substances with oxygen in the air. 
iv) Precipitation : Reaction to produce - Insoluble salts

HOW REACTION OCCUR?

According COLLISION THEORY :
1st  : Reacting particles must collide each other ;
2nd : Have minimum required energy;
3rd : Collide in the correct orientation.

Effective Collision Occurs when reacting particles have enough energy and correctly oriented when they collide. Effective Collision of REACTANTS will formed the new PRODUCTS
- Chemical Reaction occurs...
