An element 'E' gives following reaction sequence : E + N 2 → High   temp . EN → High   temp . water E ( OH ) 3 + NH 3 Element E may be:

Step-by-step solution

Aluminium and boron forms nitride with nitrogen at higher temperature due to the high bond energy of nitrogen. The reaction of boron and nitrogen forms boron nitride which is then hydrolysed to form products as follows: 2 B + N 2 → High   temp . 2 BN → High   temp . water B ( OH ) 3 + NH 3 Aluminium forms aluminium nitride and it further hydrolysed as follows: 2 Al + N 2 → High   temp . 2 AlN → High   temp . water Al ( OH ) 3 + NH 3
