Question

What is the reaction type of 3ZnS+ 2AlP = 1Zn3P2 + 1Al2S3 ?

Answer 1

Answer: double displacement

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

The balanced chemical equation is:

$3ZnS+2AlP\rightarrow Zn_3P_2+Al_2S_3$

Thus as ions get exchanged , it is double displacement reaction.
