No, Fe2O3 is ionic
Can Redox reactions change the volume?
•2Fe + 1.5 O2 > Fe2O3 • •Not always fluid dependent
What is geological Redox?
•Redox reactions can cause a change in volume •2Fe + 1.5 O2 > Fe2O3
What is the formula of rust?
Fe2 + 3O2 --> Fe2O3
How do you calculate the Fe content in FeO and Fe2O3?
Mass of Fe=(Mass of Fe2O3)(Mr Fe/ Mr Fe2O3)
Why the exposed metal rusts is a chemical change?
Assuming the metal is ferrous(contains iron) then rusting represents a chemical change because the metal (in the presence of water and oxygen) is changed into a different compound, Fe2O3. Since we started with an iron containing metal and we now have Fe2O3 which is not the same substance, a chemical change must have occurred.
What happens when you mix ammonia Fe2O3 and H2O2?
fe2o3+h2o2
What is the formula of haematite?
Hematite is an oxide of iron in its "raw" or "natural" form. It's a mineral, and it's iron(III) oxide. Its formula is Fe2O3.Hematite is Fe2O3.
What is Fe2O3 called for in periodic?
Fe2O3 (diiron trioxide) is a chemical compound not am element.
How do you balance al fe2o3?
2 Al + Fe2O3 ----> Al2O3 + 2 Fe
What are some parts of a chemical change?
Depict moles eg: Fe2O3(s) + 3CO(g)--> 2Fe(s) + 3CO2(g) 1 mole of Fe2O3 4 moles of CO 2 moles of Fe 3 moles of CO2
What iron oxide?
Iron(II) oxide is FeOIron(III) oxide is Fe2O3
