Iron(II) sulfate Wikipedia
Iron(II) sulfate. Iron(II) sulfate (British English: iron(II) sulphate) or ferrous sulfate denotes a range of salts with the formula FeSO4·xH2O. These compounds exist most commonly as the heptahydrate (x = 7) but are known for several values of x. The hydrated form is used medically to treat iron deficiency, and also for industrial applications.
Fe2O3 + H2> Fe + H2O? | Yahoo Answers
Apr 27, 2011· Best Answer: Well, to get a balanced equation on both sides, it would look like this; Fe2O3 + 6H > 2Fe + 3H2O This is so you keep the 2 Fe atoms, as well as the 2 O molecules, but in order to turn them into H2O, you need 6 Hydrogen molecules, and that's the balanced equation.
