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.
(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:

Bottom of test tube will feel cold. During the reaction, heat is absorbed. The reaction is endothermic.

Ba(OH)2+2NH4+Cl+heat----->Bacl2+2HN3+2H2+O.
