1.	Carry out the following ActivityTake about 2 g barium hydroxide in a test tube. Add 1 g of ammonium chloride anwith the help of a glass rod. Touch the bottom of the test tube with your palm. What dfeel? Is this an exothermic or endothermic reaction?
Answer» When we mix barium hydroxide with ammonium chloride, the bottom of the test tube becomes cold due to absorption of heat. So, it is an endothermic reaction. This reaction absorbs heat from its environment to be completed, so it is an endothermic reaction. Ba(OH)2+NH4Cl===>BaCl2+NH4OH
