Find he balanced molecular, total ionic and net ionic equations of the following:

1. Sulfuric acid and magnesium nitrate, 2. Sodium Carbonate and Sodium hydroxide, 3. Sodium Carbonate and magnesium nitrate, 4. sodium carbonate and strontium chloride, 5. Sodium hydroxide and magnesium nitrate, 6. strontium chloride and magnesium nitrate, 7. sodium hydroxide and strontium chloride

Solutions

Expert Solution

1. Sulfuric acid and magnesium nitrate

H2SO4(aq) + Mg(NO3)2 ---------------> MgSO4(s) + 2HNO3(aq)

2H^+(aq) +SO4^2-(aq) + Mg^2+ (aq) +2(NO3)^- ---------------> MgSO4(s) + 2H^+ (aq) +2NO3^-(aq)

removal of spectator ions to get net ionic equation

SO4^2-(aq) + Mg^2+ (aq) ---------------> MgSO4(s) net ionic equation

2. Sodium Carbonate and Sodium hydroxide,

Na2CO3 + NaOH -----------------> NO reaction

3. Sodium Carbonate and magnesium nitrate,

Na2CO3(aq) + Mg(NO3)2(aq) --------------------> MgCO3(s) + 2NaNO3(aq)

2Na^+(aq) +CO3^2-(aq) + Mg^2+(aq) +2(NO3)^-(aq) --------------------> MgCO3(s) + 2Na^+ (aq) +2NO3^-(aq)

removal of spectator ions to get net ionic equation

CO3^2-(aq) + Mg^2+(aq) --------------------> MgCO3(s) net ionic equation

4. sodium carbonate and strontium chloride

Na2CO3(aq) + SrCl2(aq)---------------> SrCO3(s) + 2NaCl(aq)

2Na^+(aq) +CO3^2-(aq) + Sr^2+ (aq) +2Cl^-(aq)---------------> SrCO3(s) + 2Na^+ (aq) +2Cl^-(aq)

removal of spectator ions to get net ionic equation

CO3^2-(aq) + Sr^2+ (aq) ---------------> SrCO3(s)   net ionic equation

, 5. Sodium hydroxide and magnesium nitrate

2NaOH(aq) + Mg(NO3)2(aq) ------------> Mg(OH)2(s) + 2NaNO3(aq)

2Na^+ (aq)+2OH^-(aq) + Mg^2+ (aq) +2(NO3)^-(aq) ------------> Mg(OH)2(s) + 2Na^+ (aq) +2NO3^-(aq)

removal of spectator ions to get net ionic equation

2OH^-(aq) + Mg^2+ (aq)------------> Mg(OH)2(s) net ionic equation

, 6. strontium chloride and magnesium nitrate

   SrCL2(aq) + Mg(NO3)2 -------------> No reaction

, 7. sodium hydroxide and strontium chloride

    2NaOH (aq) + SrCl2(aq) ----------------> Sr(OH)2(s) + 2NaCl(aq)

2Na^+ (aq) +2OH^- (aq) + Sr^2+ (aq) +2Cl^-(aq) ----------------> Sr(OH)2(s) + 2Na^+ (aq) +2Cl^-(aq)

removal of spectator ions to get net ionic equation

2OH^- (aq) + Sr^2+ (aq) ----------------> Sr(OH)2(s)   net ionic equation
