Answer 1

Answer:

1.  Combination reaction

2. Decomposition reaction

3. Single - displacement reaction

Explanation:

(a) 6 MgO (s) + 2 As₂O₅(s) → 2 Mg₃(AsO₄)  Combination reaction

(b) Bi(OH)₃(s) → Bi₂O₃(s) + 3 H₂O(g)              Decomposition reaction

(c) 2 Bi₂O₃(s) + 3 C(s) → 4 Bi(s) + 3 CO₂(g)   Single - displacement reaction

Combination reaction

A type of reaction in which an element or compound combines with

another element or compound to form a new compound

Example: 2 H₂ + O₂ → 2 H₂O  

Decomposition reaction

A type of reaction in which a compound breaks down into two or

more elements or compounds

Example: CaCO₃ → CaO + CO₂

Single - displacement reaction

A type of reaction in which a compound and an element react to form

a new element and a new compound

Example: F₂ + 2 KCl → Cl₂ + 2 KF
