Because iron oxide is not iron and the chemical/physical properties of substances are different.
Copper oxide appears as a black or dark brown powder after copper has burned.
Mars is called the red planet because its surface appears reddish in color due to the presence of iron oxide, or rust, on its surface. The iron oxide gives the planet a reddish hue when viewed from Earth.
When a magnesium ribbon is burned it combines with molecular oxygen forming magnesium oxide (MgO); the flame color is white.A huge spark. Kind of like a firework-ish. You kind of have to see it.
no.
Nitrous oxide, N2O, is a colorless gas at room temperature.
Copper oxide appears as a black or dark brown powder after copper has burned.
Iron(II) oxide (FeO) is black.
Iron OxideChemical Formula Fe2O3Looks exactly like rust (that's because it is)! It's a red-brown colour!
rust or Iron oxide
No, Hematite is basically iron oxide in a mineral state, rust is another state of iron oxide. It can be polished to a luster resembling the look of steel
No actually. The surface of Mars is covered in iron oxide ( rust ), therefore making the planet red.
Photos from the surface show Mars to look a lot like an earth desert.
Fe2O3 is ' iron(III) oxide' . Archaically and commerically it goes by the name of 'ferric oxide' or iron ore.
Lodestone is a naturally magnetized piece of magnetite, which is a naturally occurring iron oxide. Lodestone's can be black or gray with a brownish tint and is brittle and broken.
Because Iron Oxide (rust) is blended in with the soil of Mars, which is why it appears red.
Mars is called the red planet because its surface appears reddish in color due to the presence of iron oxide, or rust, on its surface. The iron oxide gives the planet a reddish hue when viewed from Earth.
Simple - Look at the formulas involved. FeO and Fe2O3 by reducing them in a blast furnace you remove the oxygen so that the become Fe only. The first FeO is black and is Iron Oxide, the other has two atoms of iron combined with three atoms of Oxygen. Fe2O3 is orange due to the formation of rust, and a common form is Haematite.
