Nitrogen gas can be obtained either from reduction of ammonia gas or from air. State giving reasons which of the two sources you would recommend to an industrialist
The system is heated to 127C and the balloon bursts. What is the pressure of the gas after the balloon bursts?
Sulfuric acid is probably the most important industrial chemical because it is used in so many industrial processes to produce or purify other chemicals. It can be produced by a three step process.
