[12%] Write net equations for each of the reactions below. Use appropriate ionic and molecular formu — Descriptive Chemistry / Chemical 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. You need not balance the equations.
Diiodine pentoxide is added to a barium hydroxide solution.
Model Answer
Ba2+(aq) + OH–(aq) + I2O5(s) → Ba(IO3)2(s) + H2O(l)
Sulfur dioxide is bubbled through an acidified solution of potassium permanganate.
Model Answer
MnO4 –(aq) + SO2(g) + H2O(l) → Mn2+(aq) + SO4 2–(aq) + H+(aq)
or MnO4 –(aq) + SO2(g) + H2O(l) + H+(aq) → Mn2+(aq) + HSO4 –(aq)
Iron(III) oxide is heated with carbon monoxide gas at 1200 °C.
Model Answer
Fe2O3(s) + CO(g) → Fe(s) + CO2(g)
Aqueous hydrobromic acid is electrolyzed at platinum electrodes.
Model Answer
H+(aq) + Br–(aq) → H2(g) + Br2(l)
1-Butanol reacts with an acidified solution of potassium dichromate.
Model Answer
+ Cr2O7 2-(aq) + H+(aq) → + Cr3+(aq) + H2O(l)
