Question

Iron(III)oxide decomposes to form solid iron and oxygen gas. Assuming 2.41L of oxygen gas is collected at STP, what mass of iron oxide decomposed?
2Fe2O3(s) --> 4Fe (s) + 3O2(g)

Answer 1

Explanation:

Iron(III) oxide

Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO) the rarer form, and iron(II,III) oxide (Fe3O4) which naturally as magnetite.
