Answer 1

Difference between exothermic and endothermic reaction.

Exothermic reaction	Endothermic reaction
1. Heat is given out during the reaction .	1. Heat is absorbed during the reaction.
2.Heat liberated is indicated by a positive sign on the product side.	2.Heat observed is indicates by negative sign on the product side .
3. An exothermic reaction is represented reactants → product + heat	3. An endothermic reaction is represented reactants → product − heat
4. Energy of the reactant is greater than the product.	4. Energy of the reactant is lesser than the product.
