What is the correct complete ionic equation? Pb^2+ + 2NO^-_3 + Gamma rightarrow

Question

What is the correct complete ionic equation? Pb^2+ + 2NO^-_3 + Gamma rightarrow PbI_2 + K^+ + NO3^- Pb^2+ + 2NO^-_3 + 2K^+ + 2 Gamma rightarrow Pb^2+ + 2I^- + 2K^+ + 2NO_3^- Pb^2+ + (NO_3)^-2 + 2K^+ + 2I^- rightarrow PbI_2(s) + 2K^+ + 2NO^-_3 Pb^2+ + 2NO^-_3 + 2K^+ + 2I^- rightarrow PbI_2(s) + 2K^+ + 2NO^-_3 none of the above When the equation, _____ N_2+ _____ H_2 rightarrow _____ NH_3 balanced, the coefficient of hydrogen is: 1 2 3 4 none of the above Considering the following precipitation reaction: Pb(NO_3)_2 (aq) + 2KI(aq) rightarrow PbI_2(s) + 2 KNO_3(aq) Which ion(s) would NOT be present in the net ionic equation? K^+, NO^-_3

Explanation / Answer

Complete ionic equation is

Pb^2+ + 2NO3^-   +   2K^+   +   2I-   ---> PbI2 (s) +    2K^+    + 2NO3^-

7) The balanced equation is N2 + 3H2 ---> 2NH3

coeffient of Hydrogen is 3

8) In net ionic equation spectator ions are not present which are K+ , NO3-
