write balanced, complete ionic and net ionic equations for each reaction a) hcl + LiOH_H2O + LiCl b) MgS + CuCl_ CuS + MgCl c) NaOH + HNO_ H2O + NaNo d) Na3PO4 + NiCl2_ Ni3(PO4)2 + NaCl

Solutions

Expert Solution

a) balanced reaction is: HCl (aq) + LiOH (aq) --------------> H2O (aq) + LiCl   (aq)

complete ionic equation is : H+ (aq) + Cl- (aq) + Li+ (aq) + OH- (aq) --------------> H2O  (aq) + Li+ (aq) + Cl- (aq)

net ionic equation is : H+ (aq) + OH- (aq) --------------> H2O  (aq)

b) balanced reaction is: 2CuCl (aq) + MgS (aq) --------------> Cu2S (aq) + MgCl2 (aq)

complete ionic equation is : 2Cu+ (aq) + 2 Cl- (aq) + Mg2+ (aq) + S2- (aq) ----> Cu2S (s) + Mg2+ (aq) + 2 Cl- (aq)

net ionic equation is : 2Cu+ (aq) + S2- (aq) -----> Cu2S (s)

c) balanced reaction is: NaOH (aq) + HNO (aq) --------------> NaNO (aq) + H2O (aq)

complete ionic equation is : Na+ (aq) +OH - (aq) + H+ (aq) + NO- (aq) ----> Na+ (aq) + NO- (aq) + H2O (aq)

net ionic equation is : H+ (aq) + OH- (aq) --------------> H2O  (aq)

d) balanced reaction is: 2 Na3PO4 (aq) + 3 NiCl2 (aq) ----------> Ni3(PO4)2 (s) + 6 NaCl (aq)

complete ionic equation is : 6 Na+ (aq) + 2 PO4^3- (aq) + Ni2+ (aq) + 6 Cl- (aq) ----> Ni3(PO4)2 (s) + 6 Na+ (aq) + 6 Cl- (aq)

net ionic equation is : 2 PO4^3- (aq) + Ni2+ (aq) ----> Ni3(PO4)2 (s)
