Balance the following ionic reactions and write the net ionic equations: PLEASE TYPE THE ANSWER DO NOT WRITE ON A PIECE OF PAPER
1) 3NH(OH)(aq) + H3PO4(aq) -----> (NH3)PO4(aq) +3H2O (I)
2) Na2O(aq) + Pb(NO3)2(aq) ----> 2NaNO3(aq) + PbO(s)
1) The molecular reaction is
3 NH4OH (aq) + H3PO4(aq) ----------------> (NH4)3PO4 (aq) + 3 H2O(l)
The ionic equation is
3 NH4+ (aq) + 3OH-(aq) + 3H + (aq) +3PO4-3(aq) ----------------> 3 NH4+ + 3PO4-3(aq) + 3 H2O(l)
The net ionic equation is written after removing the spectator ions.
The net ionic equation is
3OH-(aq) + 3H + (aq) -------------> 3H2O(l)
2)
The molecular equation is
Na2O(aq) + Pb(NO3)2 (aq) -----------------> 2 NaNO3 (aq) + PbO(s)
the ionic equation is
2Na+ (aq) + O-2(aq) + Pb+2(aq) + 2NO3-(aq) --------------> 2Na+ (aq) + 2NO3-(aq) + PbO(s)
The net ionic equation is
O-2(aq) + Pb+2(aq) -----------------> PbO(s)
