Answer 2

Warming Ammonium Chloride with Sodium Hydroxide in a test tube is an example of an Open System.

Explanation:

• The Ammonium Chloride is an inorganic salt which will be in solid state and in white colour.

• Its chemical composition is $NH_4Cl$ and its weight is 53.49 grams.

• The Sodium Hydroxide is base compound which is usually used in the manufacturing of paper, soaps etc.

• Its chemical composition is NaOH and also known to be Caustic Soda and its weight is 40 grams.

• When these two compounds are made to react by heating in a test tube the products obtained are sodium chloride, water and ammonia.

• This will release some amount of heat which gets absorbed by the two compounds and gets the equilibrium and also exchange their masses.

• This type of system is known to be as the Open System.

• The reaction is:

     $NH_4Cl + NaOH \rightarrow NaCl + H_2O + NH_3$ (on heating).
