Question

Which statement is true for the given equation?

ZnI2 + Br2

  Bromine will combine with zinc iodide during the reaction.
Bromine will replace iodine during the reaction.
No reaction will occur.
Bromine will replace zinc during the reaction.
Zince iodide will decompose into zinc and iodine during the reaction

Answer 1

the answer is E. for plato users...

Answer 2

Answer : The correct statement is, Bromine will replace iodine during the reaction.

Explanation :

When zinc iodide,
`ZnI_2` react with the bromine,
`Br_2` it gives zinc bromide,
`ZnBr_2` and iodine,
`I_2` as a product.

This reaction is a single-replacement reaction.

Single-replacement reaction : It is a reaction in which the most react metal displaces the least reactive metal.

The balanced chemical reaction will be,

`ZnI_2+Br_2\rightarrow ZnBr_2+I_2`

Hence, the correct statement is, Bromine will replace iodine during the reaction.
