Exothermic Reaction: Chemical reactions that release energy in the form of heat, light, or sound are called exothermic reactions. For example: Burning of methane in air gives heat and light. CH₄ (g)+O₂ (g) → CO₂ (g)+2H₂O(g)+heat Endothermic Reaction: Reactions that absorb energy or require energy inRead more
Exothermic Reaction: Chemical reactions that release energy in the form of heat, light, or sound are called exothermic reactions.
For example: Burning of methane in air gives heat and light.
CH₄ (g)+O₂ (g) → CO₂ (g)+2H₂O(g)+heat
Endothermic Reaction: Reactions that absorb energy or require energy in order to proceed are called endothermic reactions. For example: Silver chloride absorb the heat from sunlight and get decomposed into Silver and Chlorine.
2AgCl(s) Sunlight → 2Ag(s)+Cl₂(g)
A reaction which has an equal number of atoms of all the elements on both sides of the chemical equation is called a balanced chemical equation. The law of conservation of mass states that mass can neither be created nor destroyed. Hence, in a chemical reaction, the total mass of reactants should beRead more
A reaction which has an equal number of atoms of all the elements on both sides of the chemical equation is called a balanced chemical equation. The law of conservation of mass states that mass can neither be created nor destroyed. Hence, in a chemical reaction, the total mass of reactants should be equal to the total mass of the products. It means that the total number of atoms of each element should be equal on both sides of a chemical equation. Hence, it is for this reason that chemical equations should be balanced.

There are basically 3 types of people who depend on farming are
• Big landowners
• Small Landowners
• Landless farmers
Above all landless farmers are the poorest people as they get earning during the season after the harvesting season they have to search for the other works for which they are paid very less. So in Kalpattu Thulasi are the poorest one.
