Question

Balance the equations, (I tried to a little) I was only give the reactats side of the equation and asked to find the product side. Find the molecular, total ionic, net ionic formulas, include the states ex. aq, s, g,l. Then tell if a reaction has occured.

1. NaCl+ Fe(CH3CO2)=Na(CH3CO2)+Fe(Cl)2 2. Al(NO3)3+NaOH=Al(OH)+Na3(NO3)3 3.H3PO4+KOH=H3OH+K3(PO4) 4.Na2CO3+HBr (aq)=Na2Br+HCO3 5. H2SO4+NH3=H2H3+NSO4

Answer 1

1.

Molecular equation:

3 NaCl (aq.) + Fe(CH₃COO)₃ (s) ----------> FeCl₃ (aq.) + 3 CH₃COONa (aq.)

Ionic equation:

3Na⁺(aq.)+3Cl^-(aq.)+Fe(CH₃COO)₃ (s) ----> Fe³⁺(aq.)+3Cl^-(aq.)+3CH₃COO^-(aq.)+3Na⁺(aq.)

Net Equation:

Fe(CH₃COO)₃ (s) ---------> Fe³⁺ (aq.) + 3 CH₃COO^- (aq.)

2.

Molecular equation:

Al(NO₃)₃ (aq.) + 3 NaOH (aq.) ---------> Al(OH)₃ (s) + 3 NaNO₃ (aq.)

Ionic equation:

Al³⁺ (aq.) + 3 NO₃^-(aq.) + 3 Na⁺ (aq.) + 3 OH^- (aq.) ----> Al(OH)₃ (s) + 3 Na⁺ (aq.) + 3 NO₃^- (aq.)

Complete ionic equation:

Al³⁺ (aq.) + 3 OH^- (aq.) ----------> Al(OH)₃ (s)

3.

Molecular equation:

H₃PO₄ (aq.) + 3 KOH (aq.) --------> K₃PO₄ (aq.) + 3 H₂O (l)

Ionic equation:

3 H⁺ (aq.) + PO₄^3- (aq.) + 3 K⁺ (aq.) + 3 OH^- (aq.) ---> 3 K⁺ (aq.) + PO₄^3-(aq.) + 3 H₂O (l)

Net ionic equation:

3 H⁺ (aq.) + 3 OH^- (aq.) ------------> 3 H₂O (l)

4.

Molecular equation:

Na₂CO₃ (aq.) + 2 HBr (aq.) ----------> 2 NaBr (aq.) + CO₂ (g) + H₂O (l)

Ionic equation:

2 Na⁺ (aq.) + CO₃^2- (aq.) + 2 H⁺ (aq.) + 2 Br^- (aq.) ------> 2 Na⁺ (aq.) + 2 Br^- (a.q) + CO₂ (g) + H₂O (l)

Net ionic equation:

CO₃^2- (aq.) + 2 H⁺ (aq.) -----------> CO₂ (g) + H₂O (l)

5.

Molecular equation:

H₂SO₄ (aq.) + 2 NH₃ (aq.) ----------> (NH₄)₂SO₄ (aq.)

Ionic equation:

2 H⁺ (aq.) + SO₄^2- (aq.) + 2 NH₃ (aq.) --------> 2 NH₄⁺ (aq.) + SO₄^2- (aq.)

Net ionic equation:

2 H⁺ (aq.) + 2 NH₃ (aq.) -----------> 2 NH₄⁺ (aq.)
