Answer #1

1) MgBr2(aq)   + 2AgNO3(aq) -----------> 2AgBr(s) + Mg(NO3)2(aq) balanced reaction.

2Ag+(aq) + 2Br-(aq) -------------> 2AgBr(s) net ionic equation.

2) 2NH4Cl(aq) + Pb(NO3)2(aq) -----------> PbCl2(s) + 2NH4NO3(aq) balanced reaction

Pb+2(aq) + 2Cl-(aq) -------->  PbCl2(s) net ionic equation.

3) 2HCl(aq) + Mg(OH)2(aq) ---------> MgCl2(aq) + 2H2O(l) balanced reaction

2H+(aq) + 2OH-(aq) -----------> 2H2O(l) net ionic equation.

last reaction is acid - base reaction.
