1.	Unlike ordinary fire thermite fire cannot be stopped pouring water. Explain .
Answer» In ordinary fire, the water not only decreases the temperature of the burning material, it also cuts off the supply of `O_(2)`. However in thermite reaction. `2Al + Fe_(2)O_(3) overset("Heat")rarr Al_(2)O_(3) + 2Fe` the oxygen needed for reaction is supplied by the metal oxide (i.e, `Al_(2)O_(3)`), therefore cutting off the supply of atomospheric oxyge has no effect. Further, at high temperature (around `1270-1300 K`), Al reacts with `H_(2)O` to produce `H_(2)O` to produce `H_(2)` gas which helps to spread rather than extinguishing the fire. `2Al + 3H_(2)O overset(11270-1300K)rarr Al_(2)O_(3) + 3H_(2)`

The heavier elements of groups 13 and 14 besides the group oxidation state exhibit another oxidation state which is two units lower than the group oxidation state and the stability of this lower oxidation state increases down the group.
