In cold water NO2
forms a mixture of HNO2and HNO3, while at
higher temperatures HNO3and NO are formed. Nitric
oxide (NO) is formed by the reaction of nitrogen and oxygen.
Nitric oxide is oxidized to nitrogen dioxide (NO2) which in turn
reacts with water to give nitric acid (HNO3).
Nitrogen oxides therefore react with water to form nitric acid
and Water Reaction
Nitrogen and Oxygen do not react at ambient temperatures.
But at high temperatures, they have an endothermic reaction
producing various oxides of nitrogen. Nitric oxide, NO, is a gas
used in the manufacture of sulfuric acid; in air it forms
nitrogen dioxide, NO2, a poisonous reddish brown gas.
Nitrogen monoxide is the systematic name for nitric oxide.
Nitrogen dioxide is used to produce nitric acid and also known
as liquid dioxide, nitrogen peroxide and nitrogen tetroxide.
and Hydrogen Reaction)
or ammonium (NH4) is formed. Ammonia is a colourless
pungent gas which is lighter than air and very soluble in water
which is used mainly to produce nitrogenous fertilizers, nitric
acid, and some explosives. Ammonium compounds can occur in the
vapor phase. When ammonia vapor comes in contact with hydrogen
chloride vapor, a white cloud of ammonium chloride forms, which
eventually settles out as a solid in a thin white layer on
When Nitrogen is mixed with hydrogen either ammonia (NH3
Some examples of a chemical reaction include most commonly burning, fermentation,
tarnishing and rusting. There are several different types of Chemical reaction
which have been detailed below:
- Substitution reactions
- Combustion reactions
- Combination reactions
- Decomposition reactions
