Answer 2

Single Displacement (or single replacement) reactions involve a compound and an element in both the products and the reactants.

For example, Zn + 2HCl --> ZnCl2 + H2 ;
2AgNO3(aq) + Cu --> Cu(NO3)2(aq) + 2Ag(s)

Each side has one element and one compound.

Double Displacement (or double replacement) reactions involve compounds on both sides, and the cations are switched in the products.

For example, Fe2O3 + HCl --> FeCl3 + H2O ;
Na2SO4(aq) + BaCl2(aq) --> BaSO4(s) + 2NaCl(aq)
