Question

1) write molecular, complete ionic, and net ionic equations for the reactions that occur, if any, when solutions of the following substances are mixed: a) nitric acid and barium carbonate, b) zinc chloride and lead nitrate, c) acetic acid and sodium hydroxide, d) calcium nitrate and sodium carbonate, e) ammonium chloride and potassium hydroxide.

Answer 1

    The given reaction is :

     The moleculer reaction is

   a) 2HNO₃(aq)+BaCO₃(aq)----> Ba(NO₃)₂(s)+H₂CO₃ (aq)

        Complete ionicequation is

      2H⁺(aq)+2NO₃^-(aq)+Ba²⁺(aq)+CO₃^2-(aq)--------->Ba(NO₃)₂ (s)+ 2H⁺(aq)+CO₃^2- (aq)

       the net ionicequation

       Ba²⁺(aq)+2NO₃^-(aq)------>Ba(NO₃)₂(s)

---------------------------------------------------------------------------

    b)

    The moleculer equation is

     ZnCl₂(aq)+Pb(NO₃)₂(aq)--------->PbCl₂(s)+Zn(NO₃)₂ (aq)

    Complete ionic equation

    Zn²⁺(aq)+2Cl^-(aq)+Pb²⁺(aq)+2NO₃^-(aq)------>PbCl₂(s)+Zn²⁺(aq)+2NO₃^-(aq)

   The net ionic equation

   Pb²⁺ (aq)+2Cl^-(aq)--------->PbCl₂(s)

----------------------------------------------------------------------------

   c)

   The moleculer equation

   CH₃COOH(aq)+NaOH(aq)------>CH₃COONa(s)+H₂O(l)

Complete ionic equation

CH₃COO^-(aq)+H⁺(aq)+Na⁺(aq)+OH^-(aq)-------->CH₃COONa(s)+H⁺(aq)+OH^-(aq)

The net ionic equation is

   CH₃COO^-(aq)+Na⁺(aq)----> CH₃COONa(s)

---------------------------------------------------------------------------------

   d)

The moleculer equation is

Ca(NO₃)₂(aq)+Na₂CO₃(aq)------> CaCO₃ (s)+2NaNO₃ (aq)

Complete ionic equation is

Ca²⁺(aq)+2NO₃^-(aq)+2Na⁺+CO₃^2-(aq)---------->CaCO₃ (s)+2Na⁺(aq)+2NO₃^- (aq)

   The net ionic equation is

   Ca²⁺(aq)+CO₃^2-(aq)---------->CaCO₃ (s)

---------------------------------------------

e)

The moleculer equation is

NH₄Cl(aq)+K(OH)------> NH₄(OH)(s)+KCl(aq)

Complete ionic equation is

   NH₄⁺(aq)+Cl^-(aq)+K⁺(aq)+OH^-(aq)----->  NH₄(OH)(s)+K⁺(aq)+Cl^- (aq)

The net ionic equation is

NH₄⁺(aq)+OH^-(aq)------>NH₄(OH)(s)
