Answer:
The answer to your question is below
Explanation:
There are 4 types of chemical reactions:
- Synthesis is when two elements or compounds form only one compound.
- Decomposition is when 1 compound is broken into 2 or more products.
- Single replacement is when one element is replaced by another element.
- Double replacement is when the cations of two compounds are interchanged.
1.- Decomposition 2 Al₂O₃ ⇒ 4 Al + 3O₂
2.- Single replacement Mg + 2HNO₃ ⇒ Mg(NO₃)₂ + H₂
3.- Combustion 2C₆H₆ + 15O₂ ⇒ 12CO₂ + 6H₂O
4.- Synthesis 2Ag + S ⇒ Ag₂S
5.- Double replacement 3Ca(OH)₂ + 2H₃PO₄ ⇒ Ca₃(PO₄)₂ + 6 H₂O
