Question

1.What is carbamate?
2.Why is nitrogen gas filled in filament lamp instead of oxygen?

Answer 1

Answer:

Explanation:Main reason why electric bulb is filled with nitrogen or argon instead of air is that the bulb contains closed glass chamber with inactive (inert) gas called Argon.

Glass chamber in bulb gets filled with the air with presence of oxygen causing filament to burn to react with oxygen. Glass chamber are not made vacuum. Filament will evaporate in vacuum condition.
