Respuesta :
The classification for the following reactions as synthesis, decomposition, single displacement, double displacement, precipitation, acid-base neutralization, oxidation-reduction, or combustion are
1. Combination reaction
2. Decomposition reaction
3. Single - displacement reaction
Solution:
(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
