Abstract. Iron (III) oxide is a compound that appears in at least four different polymorphs: α-Fe 2 O 3, β-Fe 2 O 3, γ-Fe 2 O 3, and ε-Fe 2 O 3. However, Fe 3+ ions are also present in another form of iron oxide: Fe 3 O 4, which is an iron crystal structure with both Fe 2+ and Fe 3+ ions. And in its turn, Fe 2+ ions are also present in the ...

Fe2O3 is insoluble in water and exhibits weak magnetic properties. In contrast, FeO is a black solid with a cubic crystal structure. It has a lower melting point of about 1,377 degrees Celsius and a density of approximately 5.745 grams per cubic centimeter. FeO is soluble in water and possesses stronger magnetic properties compared to Fe2O3.

Step 4: Substitute Coefficients and Verify Result. Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced.
