Question

1. Write the use of thermite process?​

Answer 1

Answer:

When highly reactive metals such as Sodium, Calcium, Aluminium etc., are used as reducing agents they displace metals of lower reactivity from the compound.

These are exothermic reactions.

The amount of heat evolved is so large that the metals produced in molten state.
