"Chemical reaction:
(a) Combustion reaction
(b) Single displacement reaction
(c) Single displacement reaction
(d) Decomposition reaction
(e) Double displacement reaction
Explanation:
- The combustion reaction takes place between a compound and an oxidant which produces a product with heat.
- Calcium oxide + Carbon dioxide → Calcium carbonate
- The single displacement reaction is a reaction in which the element in the compound is replaced by the other element present in the reactant.
- Sodium + Water → Sodium hydroxide + Hydrogen
- Magnesium + Copper (II) sulphate → Magnesium (II) sulphate + Copper
- The decomposition is the reaction in which the single compound in the reactant side decomposes to produce two elements as product.
- Ammonium nitrite → Nitrogen + Water
- The double displacement reaction is a reaction takes place between two reactants. The element in the reactants interchanged to produce the two products.
- Copper (II) sulphate + Sodium hydroxide → Copper hydroxide + Sodium (II) sulphate"
