Anhydrous ammonia plays an important role in farming, especially as a nitrogen fertilizer. Nitrogen is a critical element for plant growth and development. It makes up one-sixth of amino acids, the building blocks of proteins, and chlorophyll (the compound responsible for photosynthesis). Anhydrous...

Ammonia molecule has the molecular formula NH3. In ammonia molecules, the central atom is Nitrogen that belongs to the VA group or 15th group or pnicogens or the Nitrogen family. Ammonia is a slightly basic compound, and Nitrogen is a non-metal. And, down the group, basicity increases. As...
group of the periodic table, or mixtures thereof, b) a layer of a promoter compound, selected from oxygen, sulphur or phosphorus compounds of an element of the VI, VII and VIII sub-group or a phosphoxy compound and mixtures thereof and c) a layer comprising a compound of platinum metal....
We already know that standard heat or enthalpy of formation of a substance is the heat change in forming one mole of the compound from its element in their standard states. Thus in the reaction the enthalpy of formation 2 mole of NH3 is 92kJ. Therefore the standard DH of formation = 92...
