Question

Take 3g barium hydroxide in a test tube, now add about 2g of ammonium chloride and mix the contents with the help of a glass rod.
(i) What do you feel on touching the test tube?

(ii) State the inference about the type of reaction occurred.
(iii) Write the balanced chemical equation of the reaction involved. ​

Answer 1

Answer:

(i) When it is added into ammonium chloride the bottom of test tube is found to be cooler.

(ii) it is an endothermic reaction.

(iii) Ba(OH)2 + 2NH4Cl ──⟩ BaCl2 + 2NH4OH

Answer 2

Explanation:

i) When barium hydroxide is added into ammonium chloride,the bottom of test tube is found to be cooler.

ii) This implies that its endothermic reaction.

iii) Ba(OH)2 + 2NH4Cl ---- BaCl2 + 2NH3 + 2H2O

Hope it helps !
