give one small example each of displacement decomposition and combination reaction with explanation
Answers
Displacement reaction- Those reaction in which one element takes the place on another element in a compound,are known as displacement reaction.
CuSO4 +Fe- FeSO4 +Cu
In this reaction, iron displaces copper from copper sulphate solution.
Combination reaction-Those reaction in which two or more substances combine to form a single substance are called combination reaction.
Hydrogen burns in oxygen to form water.
2H2 + O2 - 2H2O
In this reaction ,two elements, hydrogen and oxygen are combining to form a single,water.
Combination teaction means when two smaller atom combine to a single larger atom. Ex:2H2+O2»2H2O. Decomposition teaction means when a larger atom split into two or more smaller atom. Ex:CaCO3»CaO+CO2
