When iron wool is heated in bromine vapor, iron bromide is produced.
(a) Explain the type of reaction bromine atoms undergo when they are converted to bromide ions.
(b) Write a balanced reaction equation for this reaction
a) Bromine atoms undergo reduction as they are converted to Br- ions. Each bromine atom gains one electron in this process.
b) 2Fe + 3Br2 --> 2FeBr3
