Question

Barium hydroxide is mixed with ammonium chloride and stirred.

[i] Give balanced informative equation.

[ii] Will the container become warm?

[iii] What are such reactions called?

Answer 1

i)Ba(OH)2 (aq) + 2NH4Cl (aq) ==> BaCl2 (aq) + 2NH3 (g) + 2HOH (l) 
ii)no
iii)endothermic

Answer 2

1)Ba(OH)2+2NH4Cl-->BaCl2+2NH3+2HOH
2)no,it becomes cool
3)endothermic reaction which involves absorption of energy and decrease in temperature.
