Answer:
Ag will replace Pb from Pb(NO3)2.
Step-by-step explanation:
Stoichiometry means relation between proportion in which compounds reacts with each other. Silver Nitrate (AgNO3) is prepared by dissolving Silver in Nitric acid and evaporating the solution.
3Ag + 4HNO3(cold and diluted) -> 3AgNO3 + 2H2O + NO
Ag+2HNO3(hot and concentrated) -> AgNO3 + H2O + NO2
