Balance Molecular Equation Net Ionic Equation

What is a Molecular Equation?

• A balanced chemical equation in which all the reactants and products are given by their chemical formulae.

• a chemical equation that shows all soluble ionic species broken into their respective ions.

• a chemical equation showing only the species which are actively involved in the reaction.

What is a Net Ionic Equation?

• a balanced chemical equation in which all the reactants and products are given by their chemical formulae.

• a chemical equation that shows all soluble species broken into their respective ions.

• a chemical equation showing only the species which are actively involved in the reaction.

Pick the formula equation.

• AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq)

• Ag+(aq)+ NO3-(aq)+ Na+(aq)+ Cl-(aq) → AgCl(s)+ Na+(aq)+ NO3-(aq)

• Ag+(aq)+ Cl-(aq) → AgCl(s)

Pick the Net Ionic Equation.

• 2 Na₃PO₄ (aq) + 3 CaCl₂ (aq) --> 6 NaCl (aq) + Ca₃(PO₄)₂ (s)

• 6 Na⁺ (aq) + 2 PO₄^3- (aq) + 3 Ca²⁺ (aq) + 6 Cl^- (aq) --> 6 Na⁺ (aq) + 6 Cl^- (aq) + Ca₃(PO₄)₂ (s)
