6. In an experiment, 10.0 g of Na:PO4 is mixed with 20.0 g of Pb(NO:)2 and the two reactants are allowed to react according to the reaction: NasPO: (aq) + Pb(NO;): (aq) → NANO; (aq) + Pb3(PO4): (s) The following molar masses have been calculated to assist you: Ma(Na:PO.) - 163.9 g/mol M(Pb(NO,),) = 331.2 g/mol Ma(NANO:) - 85.0 g'mol Ma(Pb:(PO.):) = 811.5 g/mol a) Write the balanced chemical reaction. b) Which is the limiting reactant?

6. In an experiment, 10.0 g of Na;POa is mixed with 20.0 g of Pb(NO:)2 and the two reactants are allowed to react according to the reaction: NasPO: (aq) + Pb(NO:)2 (aq)→ NaNO; (aq) + Pba(PO4)2 (s) The following molar masses have been caleulated to assist you: Mu(Na,POs) = 163.9 g/mol M(Pb(NO,);) - 331.2 g/mol Mu(NANO:) - 85.0 g/mol Ma(Pb;(PO4):) = 811.5 g/mol a) Write the balanced chemical reaction. b) Which is the limiting reactant? 7. Calculate the amount of energy needed to convert 200. g of water at 25.0°C to steam at 150.0°C. The following information will be useful: • The heat of vaporization of water is 2256 J-g • The specific heat capacity of water is 4.184 J-g'K • The specific heat capacity of water vapour is 1.86 J-g -K
