(a) Thermit reaction, iron (III) oxide reacts with aluminium and gives molten iron and aluminium oxide.
$Fe_2O_3 + 2Al → Al_2O_3(s)+ 2Fe (l)$
This is a Single displacement reaction.

(b) Magnesium ribbon is burnt in an atmosphere of nitrogen gas to form solid magnesium nitride.
$3Mg(s) + N_2 → Mg_3N_2$
The reaction is a Combination reaction.

(c) Chlorine gas is passed in an aqueous potassium iodide solution to form potassium chloride solution and solid iodine.
$Cl_2(g) + 2KI (aq) → 2KCl(Aq) + I_2(s)$
This is a Single displacement reaction.

(d) Ethanol is burnt in air to form carbon dioxide, water and releases heat.
$C_2H5_OH+ 3O_2 → 2CO_2 + 3H_2O + heat$
This is a Combustion reaction.
