✔ 最佳答案
a. Pb(NO3)2 + 2NaCl ----------> PbCl2 + 2Na(NO3)b. Zn + 2CH3COOAg ----------> 2Ag + (CH3COO)2Zn
c. C6H14 + 13O2 ----------> 6CO2 + 7H2O
d. 3Mg + N2 ----------> Mg3N2
2a. Pb2+ + 2Na ---------->2Na+ +Pb
2b. Zn + 2Ag+ ---------->Zn2+ + 2Ag
3. Zn=65.409 g mol-1
Pb(NO3)2 = 331.2 g mol-1
N2 = 28 g mol-1
