    Iron reacts with bromine, hydrogen, concentrated sulfuric acid, dilute nitric acid, and mercury (II) chloride. The equations for the reactions are as follows:

    1. Iron + Bromine ? Iron (III) Bromide

2Fe + 3Br2 ? 2FeBr3

2. Iron + Hydrogen ? Iron (II) Hydride

2Fe + 3H2 ? 2FeH2

3. Iron + Concentrated Sulfuric Acid ? Iron (II) Sulfate

4Fe + 10H2SO4 ? 4FeSO4 + 10H2O

4. Iron + Dilute Nitric Acid ? Iron (II) Nitrate

2Fe + 6HNO3 ? 2Fe(NO3)3 + 3H2O

5. Iron + Mercury (II) Chloride ? Iron (II) Chloride

2Fe + 2HgCl2 ? 2FeCl2 + Hg2Cl2
