The balanced reaction equations for the described reactions are given below. The first reaction is a combination of a double displacement and a decomposition reaction, the second one represents single displacement reactions, and the third one is multiple double displacements.
The balanced reaction equation (including a double displacement and a decomposition) between aqueous sodium hydrogen carbonate and aqueous acetic acid (resulting in the formation of liquid water, gaseous carbon dioxide, and aqueous sodium acetate) looks like this:
NaHCO₃(aq) + AcOH(aq) → CO₂(g) + H₂O(l) + NaOAc(aq)
The balanced reaction equation between aluminum metal and iron(III) oxide (resulting in the formation of iron metal and aluminum oxide) looks like this:
2Al(s) + Fe₂O₃(s) → 2Fe(s) + Al₂O₃(s)
The balanced reaction equation between solid potassium oxide with aqueous magnesium chloride (resulting in the formation of solid magnesium hydroxide and aqueous potassium chloride) looks like this:
K₂O(s) + H₂O(l) + MgCl₂(aq) → Mg(OH)₂(s) + 2KCl(aq)
