Answer:
NiBr₃ + Al₂S₃ ⇒ NiS₃ + Al₂Br₃
Explanation:
A double replacement reaction is a reaction in which the cations switch anions.
In the reaction, the two cations are Al and Ni. The cations are Br and S.
Put each cation with the opposite anion: Ni with S and Al with Br.
The products would be NiS₃ and Al₂Br₃.
The full reaction is NiBr₃ + Al₂S₃ ⇒ NiS₃ + Al₂Br₃.
Hope that helps.
