Answer 1

the reaction that takes plau as ;- Pb(NO3)2 + 2HU Pbelle ! + 2 NO3 molarity of PbE NO37z taken = 0.30M velume of the Pb(NO3), taken = 5.0 mi - 5810 1 2- moles of Pb(NO3)2 = molarity x volne il) = 0.30 x 5x103 = 15x10*moles since I mole of Pb(NO3)2 gives Imole of Pb2t and 2 moles of nitrate or nog molarity of Hue taken = 0.30 M volume of the Hwe taken = 3.0ml - 3x10 moles of Hee = mclarityx volume = 0.3* 3x10º = 9x10 moles volume of deionized water added to redissolve - blu, a Bul Scanned with CamScanner
