Molecular Equations - Video Tutorials & Practice Problems
Molecular Equations show reacting molecules involved in a chemical reaction.
Examining Molecular Equations
Molecular Equations
In a typical molecular equation, two reactants dissociate and reorganize to form new products.
Molecular Equations Example 1
Molecular Equations Example 2
A reaction occurs only if solid, gas or liquid water is formed. If both products are aqueous, NO REACTION has occurred.
Predict whether a chemical reaction occurs and write the balanced molecular equation.
Ag2SO4 (aq) + KCl (aq) →
Predict whether a chemical reaction occurs and write the balanced molecular equation.
MgBr2 (aq) + NaC2H3O2 (aq) →
MgBr2 (aq) + NaC2H3O2 (aq) → NaBr (aq) + Mg(C2H3O2)2 (aq)
MgBr2 (aq) + NaC2H3O2 (aq) → 2 NaBr (aq) + Mg(C2H3O2)2 (aq)
MgBr2 (aq) + 2 NaC2H3O2 (aq) → 2 NaBr (aq) + Mg(C2H3O2)2 (aq)
No reaction
Determine the balanced equation for the neutralization equation
Ca(OH)2 (aq) + HCN (aq) →
Ca(OH)2 (aq) + 2 HCN (aq) → 2 Ca(CN)2 (aq) + 2 H2O (l)
Ca(OH)2 (aq) + HCN (aq) → Ca(CN)2 (aq) + 2 H2O (l)
Ca(OH)2 (aq) + 2 HCN (aq) → Ca(CN)2 (aq) + H2O (l)
Ca(OH)2 (aq) + 2 HCN (aq) → Ca(CN)2 (aq) + 2 H2O (l)
