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)

Homework Answers

Answer #1

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)
