1.	Take about 2g of barium hydroxide in a test tube. Add 1g of ammonium chloride and mix with the help of a glass rod. Touch the bottom of the test tube with your palm. What do you feel? Is this an exothermic or endothermic reaction?
Answer» ANSWER: It is an endothermic reaction. Explanation: When barium hydroxide is ADDED to ammonium hydroxide then it results in the formation of barium chloride and ammonium hydroxide. The chemical reaction equation is as follows. $Ba(OH)_{2} + 2NH_{4}Cl \rightarrow BaCl_{2} + 2NH_{4}OH$ This reaction is endothermic in nature because when barium hydroxide is added in ammonium chloride then they absorb HEAT.

Answer»

ANSWER: It is an endothermic reaction.

Explanation:

When barium hydroxide is ADDED to ammonium hydroxide then it results in the formation of barium chloride and ammonium hydroxide.

The chemical reaction equation is as follows.

$Ba(OH)_{2} + 2NH_{4}Cl \rightarrow BaCl_{2} + 2NH_{4}OH$

This reaction is endothermic in nature because when barium hydroxide is added in ammonium chloride then they absorb HEAT.
