Question

WRITE BALANCED MOLECULAR EQUATIONS FOR THE FOLLOWING WORD EQUATIONS:
(ii)Aluminium bromide + Chlorine ​→ Aluminium chloride + Bromine

Answer 1

Dear student,
Aluminium bromide + Chlorine $\to$Aluminium chloride + Bromine
The chemical equation for the word equation written above is:
AlBr₃ +Cl₂ $\to$ AlCl₃ +Br₂
​To balance Chlorine : As there are 3Chlorine molecules on right hand side and two chlorine molecules on left hand side, the Cl on left side is multiplied by 3 and on right side is multiplied by 2
There are 2 Bromine molecules on right side and three Bromine molecules on left side.We place 3 in front of Bromine in right side and 2in front of AlBr3 on the left side , the equation becomes:
2​AlBr₃ + 3Cl₂ $\to$ 2AlCl₃ +3Br₂
