Solve this : Write the reaction in equation and is the reaction endothermic or exothermic ?
Q. Take about 2g barium hydroxide in a test tube. Add 1 g of ammonium chloride and mix with the help of a glass rod. Touch the bottom of the test tube with your palm. What do you feel? Is this an exothermic or endothermic reaction?

Dear Student,
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.
Ba(OH)2 + NH4Cl ------ BaCl + NH4(OH)2.
This reaction absorbs heat from its environment to be completed, so it is an endothermic reaction.
