PLEASE help!!

Which of the following would represent a single displacement reaction between Potassium Bromide (K+Br-) and Iodine (I), which forms iodide (I-)?


KBr + I -> KI + Br


KBr + I -> KBr + I


KBr + I -> K + IBr

Respuesta :

Answer:

KBr + I- ---------> KI + Br-

Explanation:

Single Displacement reaction is a chemical Reaction in which one element in the salt is replaced with another element

for example,

A-B + C -------> A-C + B

electropositive replaces only electropositive elements from compound. same is true for electronegative element

in first reaction I being electro negative replaces Br from KBr so this is a single displacement reaction
