• That means the total mass before and after chemical reaction remain same

• Reactant are the substance that take part in the chemical reaction
• product are the substance that results in a chemical reaction

• Chemical reaction - The reaction in which there is a formation of new substance and the property of initial substance changes

• Types of chemical reaction (common type)

1. Combination reaction
2. Decomposition reaction
3. Displacement reaction
4. Double Displacement reaction
5. Precipitation reaction
6. Exothermic reaction
7. Endothermic reaction

• Characteristics of chemical reaction

1. Evolution of gas
2. change in state
3. change in temperature
4. change in colour
5. formation of precipitate
