The reaction in which more reactive element displaces less reactive element known as displacement reaction.
For example:-
CuSO4 +Fe ----------> FeSO4 +Cu
In above reaction the Fe (Iron) is more reactive than Cu (Copper) according to modern periodic table.Hence it displaces Cu from the solution of Copper Sulphate and form Ferrous Sulphate and Copper metal.
In more easy way AB+C ------>A+BC In this C is more reactive than A so C will displace A and combines with B
What is friction?
The resistance that one surface or object encounters when moving over another.a lubrication system which reduces friction’ It's or...
