(Solution Download) Stoichiometry

A weighted sample of iron (Fe) is added to liquid bromine and allowed to react completely. The reaction produces a single product, which can be isolated and weighed. The experiment was repeated a number of times with different masses of iron but with the same mass of bromine. See graph.


1g Fe = 6g product


2g Fe = 11g product


3g Fe = 11g product


4g Fe = 11g product


What is the formula for the product formed? Write the correct balanced chemical equation for the reaction of iron and bromine
