Question

 Displacement and Double displacement reaction.  Oxidation and Reduction reaction.  Balanced and unbalanced chemical equation.  Corrosion of iron and Coppe

Answer 1

Answer:

Displacement reaction take place when the more reactive metal displaces another metal

In double displacement reaction an exchange of ions between the reactant and product

Oxidation -

Loss of electrons

Gain of oxygen

Loss of hydrogen

Reduction is vice versa of oxidation

Balanced equation represents equal no. Of atom of each element in reactant side

Unbalanced equation is vice versa of balanced equation.

Corrosion of iron

4Fe +3O2 + H2O -----> 2FeO3 + H2O

Corrosion of copper

Cu + H2O +CO2 ---> CuCO3 + Cu( OH)2
