4- Given the following balanced reagent equations, derive the net equation for each (a) Znes) + Cu(NO3½(aq) Cys) + Zn(NO3)2(aq) (c) Cr(CO)+ 6 HNO, ()- 2 Cr(NO) )3 H,0+3 CO2 5- Complete and balance each of the following as a net ionic equation by indicating whether a precipitate forms (Hint: Look at the combinations of cations and anions possible after mixing the reagents and then check the ionic solubility table)· lf no reaction occurs, so state. Finally, if a precipitation does occur, go back and complete and balance the reagent equation. (a) Ca(NOJ2(aq) + (NH,),CO- (b) AgNO3(aq) + Na,PO4(aq) (c) NaOH,aq) + FeCl3(aq) (d) MgCl2 (aq) + CuSO4 (aq)Explanation / Answer
4).
a) Zn(s) + Cu(NO3)2(aq) ----------Cu(s) + Zn(NO3)2(aq)
Zn(s) + Cu+2(aq) + 2 NO3-(aq) ---------------- Cu(s) + Zn+2(aq) + 2 NO3-(aq)
Zn(s) + Cu+2(aq) ----------------------- Cu(s) + zn+2(aq)
b) PbCl2(aq) + Na2S(aq) --------------- PbS(s) + 2 NaCl(aq)
Pb+2(aq) + 2 Cl-(aq) + 2 Na+(aq) + s-2(aq) ----------------- PbS(s) + 2 Na+(aq) + 2 Cl-(aq)
Pb+2(aq) + S-2(aq) --------------- PbS(s)
c).Cr2(CO3)3(s) +6 HNO3(aq) ------------ 2 Cr(NO3)3(aq) + 3 H2O(l) + 3 CO2(g)
Cr2(CO3)3(s) + 6 H+(aq) + 6 NO3-(aq) ---------- 2 Cr+3(aq) + 6 NO3-(aq) + 3 H2O(l) + 3 CO2(g)
Cr2(CO3)3(s) + 6 H+(aq) -------------- 2 Cr+3(aq) + 3 H2O(l) + 3 CO2(g)
5).
a) Ca(NO3)2 (aq) + (NH4)2CO3(aq) ------------- CaCO3(s) + 2 NH4NO3(aq)
Ca+2(aq) + 2 NO3-(aq) + 2 NH+(aq) + CO3-2(aq) --------- CaCO3(s) + 2 NH4+(aq) + 2 NO3-(aq)
Ca+2(aq) + CO3-2(aq)------------------ CaCO3(s)
b).3 AgNO3(aq) + Na3PO4(aq) -------------- Ag3PO4(s) + 3 NaNO3(aq)
3 Ag+(aq) + 3 NO3-(aq) + 3 Na+(aq) + PO4-3(aq) --------------- Ag3PO4(s) + 3 Na+(aq) + 3 NO3-(aq)
3 Ag+(aq) + PO4-3(aq) --------------- Ag3PO4(s)
c)3.NaOH(aq) + FeCl3(aq) -------------- Fe(OH)3(s) + 3 NaCl(aq)
3 Na+(aq) 3 OH-(aq) + Fe+3 (aq) + 3 Cl-(aq) ------------------ Fe(OH)3(s) + 3 Na+(aq) + 3 Cl-(aq)
Fe+3(aq) + 3 OH-(aq) ---------- Fe(OH)3(s)
d).MgCl(aq) + CuSO4(aq) ------------ No reaction
