Iron ore is made of what mineral?
Iron ore is typically an oxide of iron. Haematite is very commonly mined this is a mineral form of Fe2O3. Magnetite has been mined , this is a form of Fe3O4.
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.
How does iron react with steam when heated?
Fe is the chemical symbol for iron. When iron reacts with steam it corrodes, or rusts.
What is rust composed of?
Rust (in its "regular" red form) is an iron oxide called iron(III) oxide. It's formula is Fe2O3, and we call it ferric oxide or hematite. And that's different from iron (II) oxide FeO, or iron (II,III) oxide Fe3O4. There are three basic forms of oxidized iron, and there they are. Wikipedia has more information, and a link to their post is provided below. Rust is basically ferric oxide caused by the action of air, or to be more precise, the action of oxygen and water droplets on iron.
What is the biggest impurity in the extraction of iron?
The problems that iron impurities can cause in a blast furnace can include the iron not melting down correctly, obnoxious fumes being created, and the impurities could ruin an entire batch of melted iron.
Is Fe3O4 a compound or element?
element
Is iron oxide a element compound or a mixture?
Iron oxide is a compound. There are a number of different oxides of iron FeO, Fe2O3 and Fe3O4
What is the chemical compound for magnetite?
Magnetite is Fe3O4.
Is iron a compound or an element?
"An iron" is a tool for removing the wrinkles from clothes. "Iron" is an element as it is found in the Periodic Table.
What is the chemical compound for iron?
Iron is an element, not a compound; a wide variety of compounds can be formed from Iron (Fe)
Is iron oxide a non stoichiometric compound?
is fe3o4 non stoichiometric
Is hornblende an element or compound?
Yes it is. Hornblende under chain silicates group. Diagram below shows which group and sub-groups it belongs to:CHAIN SILICATES1. Pyroxenes2. AmphibolesHornblende (is here)OxyhornblendeEtc.3. Pyroxenoids4. Other Chain Silicates
Is magnetite metalic?
No. Magnetite is the compound iron II, III oxide, Fe3O4
What is the valency iron in Fe3o4?
Itron has both 2 and 3 valencies int his compound
How do you find the valency of each element in Fe3O4?
This is an especially complicated valency problem, because Fe3O4 is a combination of Fe2O3 and FeO. As usual, except in peroxides and superoxides, oxygen is assigned a valency of -2. This means that the iron in Fe2O3 has a valency of +3 while the iron in FeO has a valency of +2. (Note that these two oxides of iron also occur separately from each other, as well as in Fe3O4.) Therefore, the average valency of iron in Fe3O4 is 8/3, a rare example of fractional valency made possible only by the fact that iron in this compound actually exists in two integral valence states in the same compound.
What is the chemical formula for oxygen and iron III?
Fe3O4 (The numbers are subscripts, meaning they are smaller, and go beside the element.)
The compound that is made of atoms of iron and oxygen is?
These compounds are iron oxides as FeO, Fe2O3, Fe3O4.Rust.
