[12%] Write net equations for each of the reactions below. Use appropriate ionic and molecular formu — Descriptive Chemistry / Organic Reactions Chemistry Question
Problem Context
[12%] Write net equations for each of the reactions below. Use appropriate ionic and molecular formulas and omit formulas for all ions or molecules that do not take part in a reaction. Write structural formulas for all organic substances, and clearly show stereochemistry where relevant. You need not balance the equations or show the phases of the species.
Sulfur dioxide is bubbled through barium hydroxide solution.
Model Answer
Ba2+(aq) + SO2(g) + OH–(aq) → BaSO3(s) + H2O(l)
Phosphorus pentachloride is heated with phosphorus(V) oxide.
Model Answer
PCl5(s) + P4O10(s) → POCl3(l)
Cobalt(II) nitrate is dissolved in concentrated aqueous hydrochloric acid.
Model Answer
Co(NO3)2(s) + Cl–(aq) → CoCl4 2–(aq) + NO3–(aq)
Iron(II) ammonium sulfate reacts with potassium dichromate in dilute sulfuric acid.
Model Answer
Cr2O7 2–(aq) + Fe2+(aq) + H+(aq) → Cr3+(aq) + Fe3+(aq) + H2O(l)
