Answer
(a) BaCO$_{3}$(s) → BaO(s) + CO$_{2}$(g)
Decomposition
(b) 4Fe(s) + 3O$_{2}$ (g) → 2Fe$_{2}$O$_{3}$ (s)
Combination
(c) 2Al(s) + Mn$_{2}$O$_{2}$ (s) → 2Mn(s) + Al$_{2}$O$_{3}$ (s)
Single displacement
(d) 2AgNO$_{3}$ (aq) + H$_{2}$SO$_{4}$ (aq) → Ag$_{2}$SO$_{4}$ (s) + 2HNO$_{3}$ (aq)
Double displacement
