List the uses of neon and argon gases.

Text Solution

Verified by Experts

Uses of neon gas:
(i) It is mixed with helium to protect electrical equipments from high voltage.
(ii) It is filled in discharge tubes with characteristic colours.
(iii) It is used in beacon lights.
Uses of Argon gas:
(i) Argon along with nitrogen is used in gas-filled electric lamps. This is because Ar is more inert than N.
(ii) It is usually used to provide an inert temperature in a high metallurgical process.
(iii) It is also used in laboratories to handle air-sensitive substances.

List the used of nean and argon gases.

A closed container of volume 0.02m^(3) contains a mixture of neon and argon gases at a temperature 27^(@)C and pressure 1 xx 10^(5) Nm ^(-1) The total mass of and argon are 20 and 40 respectively find the masses of individual gases in the container assuming then to be ideal .

A closed container of volume 0.02m^3 contains a mixture of neon and argon gases, at a temperature of 27^@C and pressure of 1xx10^5Nm^-2 . The total mass of the mixture is 28g. If the molar masses of neon and argon are 20 and 40gmol^-1 respectively, find the masses of the individual gasses in teh container assuming them to be ideal (Universal gas constant R=8.314J//mol-K ).
