Question

Take 3 g of barium hydroxide in a test tube, now add about 2 g of ammonium chloride and

mix the contents with the help of a glass rod. Now touch the test tube from outside.

(a) What do you feel on touching the test tube?

(b) State the inference about the type of reaction occurred.

(c) Write the balanced chemical equation of the reaction involved.​

Answer 1

Explanation:

a) When barium hydroxide is added into ammonium chloride,the bottom of test tube becomes cooler. We observe that its an endothermic reaction.

b) The reaction is endothermic as the test tube cools down

c) Ba(OH)2 + 2NH4Cl -------> BaCl2 + 2NH4OH
