1.	What does meant by exothermic and endothermic reaction give examples
Answer» Exothermic Reaction: A chemical reaction in which heat is given out is known as exothermic reaction. For exampleC(g) + O2(g) → CO2(g) + Heat energyNaOH (aq) + HCl (aq) → NaCl(aq) + H2O(l) + EnergyEndothermic Reaction: A chemical reaction in which heat energy is absorbed is known as endothermic reaction. For exampleN2(g) + O2(g) → 2NOC(s) + H2O(l) → CO(g) + H2(g)
