Question

27. What is thermite process and it's applications?
28. What is Homologus series write it's characteristics?​

Answer 1

Answer:

Thermite process :

When highly reactive metals such as Sodium, Calcium, Aluminium etc., are used as reducing agents they displace metals of lower reactivity from the com-pound. ... The reaction of iron oxide with aluminium is used to join railing of railway tracks or cracked machine parts.

Features include a general formula and neighbouring members differing by CH2, with similar chemical properties and with a gradation in physical properties. Homologous series are 'families' of organic compounds. They share common characteristics: They all contain the same functional group.

Answer 2

Answer:

1)When highly reactive metals such as sodium , aluminium, calcium etc . are used as reducing agents they displace metals of lower reactivity from the compound.The reaction of iron oxide with aluminium is used to join railing of railway tracks or cracked machine parts . This reaction is known as the thermite process.
