1.	Heating of ammania is presence of oxygen leads to the formation of which gas
Answer» Answer: Nitrogen dioxide(brown gas) Explanation:4NO+5O2=(catalyst:Pt,800℃)6H2O+4NO+Heat 2NO+O2=2NO2(brown gas) In the PRESENCE of platinum at 800℃,AMMONIA reacts with oxygen to give nitric oxide and WATER vapour. OBSERVATIONS: 1.Reddish brown vapours of nitrogen dioxide are SEEN in the flask due to the oxidation of nitric oxide. 2.The platinum CONTINUES to glow even after the heating is discontinued since the catalytic oxidation of ammonia is an exothermic reaction.

Heating of ammania is presence of oxygen leads to the formation of which gas

Answer»

Answer: Nitrogen dioxide(brown gas)

Explanation:4NO+5O2=(catalyst:Pt,800℃)6H2O+4NO+Heat

2NO+O2=2NO2(brown gas)

In the PRESENCE of platinum at 800℃,AMMONIA reacts with oxygen to give nitric oxide and WATER vapour.

OBSERVATIONS:

1.Reddish brown vapours of nitrogen dioxide are SEEN in the flask due to the oxidation of nitric oxide.

2.The platinum CONTINUES to glow even after the heating is discontinued since the catalytic oxidation of ammonia is an exothermic reaction.
