A weighed sample of iron (Fe) is added to liquid Bromine (Br2) and allowed to react totally. The reaction forms a single product, explain which can be isolated and weighed. The experiment is repeated a number of times with different masses of iron but with the same mass of bromine.
The graph data in words:
5.5 gram product when 1 gram Fe
10.5 gram product when 2 gram Fe
0 gram product when 0 g Fe
10.5 gram product when 4 gram Fe
10.5 gram product when 3 gram Fe
10.5 gram product when 5 gram Fe
1. Explain what mass of Br2 is used when the reaction consumes 2 g Fe?
2. Calculate the balanced chemical equation for the reaction of bromine and iron?
