34.In an experiment 2 mol of Pb(NO3)2 and 3 mol of NaI are mixed and the reaction represented by the balanced equation occurs:Pb(NO3)2 + 2 NaI → PbI2 + 2 NaNO3.The solid produced is separated from the solution, while more water is added to NaNO3 until a volume of 1000 mL is completed. The limiting reagent in the reaction is the:Immersion reader. Pb(NO3)2+2NaI------PbI2 + 2NaNO3 Pb(NO3)2 , because stoichiometrically fewer moles are required for the reaction NaI, because the reacting mass is lower NaI, because according to stoichiometry, it is completely consumed Pb(NO3)2 because it is in smaller amount than NaI
