Study the following reaction carefully. What classification should this reaction have? 4Al + 3O 2 2Al 2 O 3 synthesis decomposition single replacement double displacement

4 Al + 3O₂ → 2Al₂O₃

The classification of above reaction is synthesis

Explanation

Synthesis reaction is type of chemical reaction in which two or more simple substance combine to form a more complex product. React may be elements or compounds. In the reaction above Al combine with O₂ to form Al₂O₃ therefore it is synthesis reaction.
