Question

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

Answer 1

 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.
