Question

Take 3g of Barium hydroxide in a test tube now add 2g of Ammonium chloride and mix the contents with the help of a glass rod. Now touch the test tube from outside.
(1) What do you feel on touching the test tube?
(2) State the inference about the type of reaction occurred.
(3) Write the balanced chemical equation for the same.

Answer 1

the test tube becomes cooler

endothermic reaction

baOH2+2NH4CL->BACL2+2NH4OH

Answer 2

Answer:

Explanation:

1) cool to touch

2)the reaction here will be endothermic as it involves heat.

3) BaOH2 + 2NH4Cl ---> BaCl2 +2NH4 OH
