QUESTION 6
Based on your understanding of the solubility rules, which of the following would be the correct net ionic equation for the reaction between cesium sulfate (Cs2SO4) and lead nitrate (Pb(NO3)2)?
no reaction
2 Cs+ + SO42- + Pb2+ + 2 NO3- --> 2 CsNO3 + PbSO4
SO42- + Pb2+ --> PbSO4
2 Cs+ + 2 NO3- --> 2 CsNO3

QUESTION 7
Based on your understanding of the solubility rules, which of the following would be the correct net ionic equation for the reaction shown below?
ZnCl2 + 2 NaNO3 --> 2 NaCl + Zn(NO3)2
no reaction
Zn2+ + 2 Cl- + 2 Na+ + 2 NO3- --> 2 Na+ + 2 Cl- + Zn2+ + 2 NO3-
2 Cl- + 2 Na+ --> 2 NaCl
Zn2+ + 2 NO3- --> Zn(NO3)2
no reaction
2 Cs+ + SO42- + Pb2+ + 2 NO3- --> 2 CsNO3 + PbSO4
SO42- + Pb2+ --> PbSO4
2 Cs+ + 2 NO3- --> 2 CsNO3
Explanation / Answer
1) Cesium sulfate (Cs2SO4) and lead nitrate (Pb(NO3)2)
Cs2SO4(aq) +Pb(No3)2 (aq) ---> PbSO4(s) + 2CsNO3(aq)
net ionic : SO4^-2 (aq) + Pb+2 (aq) --->PbSO4(s) option C (answer)
2)
ZnCl2 (aq) + 2 NaNO3 (aq) --> 2 NaCl(aq) + Zn(NO3)2(s)
net ionic : Zn+2 (aq) + 2NO3-(aq) --->Zn(NO3)2(s) (answer) optionD
