Will the same result be obtained if `CaCO_(3)` is heated in an open vessel and in a closed container separately? Explain.

Will the same result be obtained if CaCO_3(s) is heated in an open vessel and in a closed vessel separately?

When NH_4SCN is added to the aquous solution of FeCl_3 the solution turns red but with addition of NH_4CI fedds the red Coluration. Explain. Shall it give same result if CaCO_3 is heated in a open and closed Container separately?

What is a reversible reaction? What is rate of a reaction? Would you get the same result during heating of CaCO_3 separately in an open container and a closed container? Give reason.

What happens when (1) H_(2)SO_(4) is kept in an open vessel and (2) H_(2)SO_(4) is kept in a closed vessel ?

Classify as open, closed or isolated system: (1) A cup of coffee placed on a table (2) Water in a beaker is boiled by heating (3) Lead nitrate is heated in a test tube (4) Solid NH_(4)Cl is heated in a closed vessel (5) Substances present in a soda-water bottle (6) Mercury enclosed in the thermometer.

The apparent coefficient of expansion of a liquid when heated in a copper vessel is C and when heated in a silver vessel is S. If A is the linear coefficient of expansion of copper, then show that the linear coefficient of expansion of silver is (C+3A-S)/3 .

When NaNO_3 is heated in a closed vessel, oxygen is liberated and NaNO_2 is left behind. At equilibrium

Explain the relation between pressure and volume of a gas confined in a closed vessel at a constant temperature,according to the kinetic theory of gases.
