Chemistry

Write the balanced complete ionic equations and net ionicequations for the reactions that occur when each of the followingsolutions are mixed. (Type your answers using the format [NH4]+ forNH4+ or Ca3(PO4)2 for Ca3(PO4)2. Use the lowest possiblecoefficients.)

(a) Cr2(SO4)3(aq) and (NH4)2CO3(aq)

complete ionic equation:
  (aq) +  CO32-(aq) +  Cr3+(aq)+  SO42-(aq)    (s) +  NH4+(aq)+   (aq)

net ionic equation:
Cr3+(aq) +   (aq)    (s)




(b) FeCl3(aq) and Ag2SO4(aq)

complete ionic equation:
  (aq) +  Cl-(aq) +  Ag+(aq)+  SO42-(aq)    (s) +  Fe3+(aq)+   (aq)

net ionic equation:
Ag+(aq) +   (aq)    (s)




(c) Al2(SO4)3(aq) and K3PO4(aq)

complete ionic equation:
  (aq) +  PO43-(aq) +  Al3+(aq)+  SO42-(aq)    (s) +  K+(aq)+   (aq)

net ionic equation:
Al3+(aq) +   (aq)    (s)

(a) Cr2(SO4)3(aq) and (NH4)2CO3(aq)

Balanced equation:

Cr2(SO4)3 + 3 (NH4)2CO3 -------------> 3 (NH4)2SO4 + Cr2(CO3)3

Complete ionic equation:

2(Cr)2+(aq) + 3(SO4)2-(aq) + 6(NH4)+(aq) + 3(CO3)2-(aq) -------------->Cr2(CO3)3(s) + 6(NH4)+(aq)+ 3(SO4)2-(aq)

Net ionic equation:

2(Cr)2+(aq) + 3(CO3)2-(aq) -------------->Cr2(CO3)3(s)

---------------------------

(b)

FeCl3(aq) and Ag2SO4(aq)

Balanced chemical reaction:

2 FeCl3 + 3 Ag2SO4 = 6 AgCl + Fe2(SO4)3

Complete ionic equation:

2Fe+3 + 6Cl-(aq) + 6Ag+(aq) + 3SO42-(aq) -----------> 6AgCl(s) + 2Fe+3 + 3SO42-(aq)

Net ionic equation:

6Cl-(aq) + 6Ag+(aq) -----------> 6AgCl(s)

----------------------------

(c)

Al2(SO4)3(aq) and K3PO4(aq)

Balanced equation:

Al2(SO4)3(aq) + 2 K3PO4 ----------> 2 AlPO4 + 3 K2SO4

Complete ionic equation:

2Al3+(aq) + 3(SO4)2-(aq) + 6K+(aq) + 2(PO4)3-(aq) -------> 2 AlPO4(s) + 6K+(aq) +   3(SO4)2-(aq)

Net ionic equation:

2Al3+(aq) + 2(PO4)3-(aq) -------> 2 AlPO4(s)
