CHEMICAL REACTIONS AND EQUATIONS
1. During chemical reactions, chemical composition of substances changes or new substances are formed.
2.Chemical reactions can be written in chemical equation form which should be always balanced.
3. Types of Chemical Reactions
4. i)Exothermic reaction: A chemical reaction in which heat energy is evolved.
C + O2 →CO2 (g) + heat
ii)Endothermic reaction: A chemical reaction in which heat energy is absorbed.
ZnCO3 + Heat →ZnO + CO2
5 .Redox reaction: Chemical reaction in which both oxidation and reduction take place simultaneously.
Oxidation: Reaction that involves the gain of oxygen or loss of hydrogen.
Reduction: Reaction that shows the loss of oxygen or gain of hydrogen
ZnO + C →Zn + CO
ZnO is reduced to Zn -reduction
C is oxidized to CO ------oxidation
6. Effectsof oxidation reactions in our daily life:
a)Corrosion: It is an undesirable change that occurs in metals, when they are attacked by moisture, air, acids and bases.
Corrosion (rusting) of iron: Fe2O3. xH2O (Hydrated iron oxide)
Corrosion of copper:CuCO3.Cu (OH)2 (Basic copper carbonate)
Corrosion of silver:Ag2S (Silver sulphide)
Corrosion of Aluminum: Al2O3 (Aluminum oxide)
b)Rancidity: Undesirable change that takes place in oil containing food items due to the oxidation of fatty acids.
Preventive methods
(1)Adding antioxidants to the food materials.
(2) Storing food in air tight container
(3) Flushing out air with nitrogen gas.
(4) Refrigeration
