• Sr(NO₃)_{2 (aq)} + K₂SO_4(aq) →

• AgNO₃(aq) + Na₂S(aq) →

•  Pb(NO₃)₂(aq) + AgNO₃(aq) →

Mixing Al(NO₃)_{3 (aq)} and NH₄OH _(aq) results in the formation of a white precipitate. What is the molecular equation for this reaction?

• Al³⁺ _(aq) + 3 OH^- _(aq) → Al(OH)_{3 (s)}

• Al(NO₃)_{3 (aq)} + 3 NH₄OH _(aq) → Al(OH)_{3 (s)} + 3 NH₄NO_{3 (aq)}

• NH₄OH _(aq) → NH₄⁺ _(aq) + OH^- _(aq)

• Al(NO₃)_{3 (aq)} → Al³⁺ _(aq) + 3 NO₃^-_(aq)
