2. LEARNING OBJECTIVES
1. Chemical Reactions
2. Balancing of Chemical Equations
3. Types of Chemical Equations

3. CHEMICAL REACTIONS
 It is the process in which two or more substances (reactants) are
converted into one or more than one product. The property of the new
product is fully different from the property of the reactants.
 This image is showing rusting of a iron nail.
 Rust always form on the surface of iron.
 It is formed due to the oxidation of iron.

4. RUST
• Fe2O3·xH2O
• The chemical name of rust is Iron Oxide.
• Here Fe2O3 is Ferric Oxide and ·xH2O is the Water of Crystallization.
 It is a reddish-brown substance which
forms a layer on the surface of iron when
contact with air and moisture.

5. SOME DAILY LIFE CHEMICAL REACTIONS
Some daily life chemical reactions are:-
• Digestion
• Combustion
• Photosynthesis
• Respiration

7. WHAT IS A BALANCED EQUATION ?
 It is an equation for a chemical reaction in which the number of atom of
an element and total mass is the same for both the reactant and the
product.

8. WHY IS BALANCING IMPORTANT ?
 A chemical equation should always be balanced because the Law of
Conservation of Mass which states matter can neither be created nor
destroyed.

9. TYPES OF CHEMICAL REACTIONS
6 primary chemical reactions are:-
 Combination Reaction
 Decomposition Reaction
 Displacement Reaction
 Double Displacement Reaction
 Precipitation Reaction
 Acid – Base Reaction

10. COMBINATION REACTION
 It is a chemical reaction in which two reactants combine together to
form a new product.

11. DECOMPOSITION REACTION
 It is a chemical reaction in which the product breaks down into two or
more reactants.

12. DISPLACEMENT REACTION
 It is a reaction in which a atom get displaced by another atom in a
molecule.

13. DOUBLE DISPLACEMENT REACTION
 It is a type of reaction in which two reactants exchange ions to form two
new compounds.

14. PRECIPITATION REACTION
 It is a double displacement reaction which involves the production of a
solid residue called precipitate.

15. ACID-BASE REACTION
 It is a chemical reaction which occurs between an acid and a base.

16. ACID-BASE REACTION
 It is a chemical reaction which occurs between an acid and a base.
