In a single replacement reaction between silver nitrate AgNO3 solution and copper Cu metal, copper will replace silver in the silver nitrate compound, resulting in the formation of copper nitrate Cu NO3 2 and silver Ag metal.The balanced chemical equation for the reaction is:2AgNO3 aq + Cu s Cu NO3 2 aq + 2Ag s This reaction will occur because copper is more reactive than silver, and it can displace silver from its compound.
