Why Rust is compound?
A compound is 2 or more elements permanently combined. Rust is a combination of iron and oxygen, both elements- into iron oxide, a compound.
What 2 elements make up rust?
Iron and oxygen
Why some elements have variable valencies?
Certain elements combine with other atoms, donating, accepting or sharing electrons in different proportions depending on the nature of the reaction. For example, iron combines with oxygen to form ferrous oxide as well as ferric oxide. In the formation of ferrous oxide, iron exhibits a valency of +2, whereas in ferric oxide, it has a valency of +3. This is termed variable valency
Is titanium oxide a binary compound?
Yes it is. Binary means it contains only 2 elements.
Does chromite have iron in it?
Chromite is an iron chromium oxide: FeCr 2 O 4
Why Rust is compound?
A compound is 2 or more elements permanently combined. Rust is a combination of iron and oxygen, both elements- into iron oxide, a compound.
What 2 substances contain iron?
No elements are made up of a compound. I think you mean 'Which elements make up iron oxide?', and the answer to that is iron and oxygen.
Element of compound ferrous oxide?
It is not an element. It is an compound made of two elements: Iron and Oxygen, FeO.
What 2 elements make up rust?
Iron and oxygen
What elements do Fe2O3 contain?
Fe2O3 contains the elements Iron and Oxygen. It would have 2 Iron and 3 oxygen.
What 2 elements composes carbon dioxide?
carbon and oxygen
What is the word equation for iron oxygen?
iron oxide
What are the elements in the compound Fe2O3?
well Fe is one element and O is another, so there are two, but since there are numbers next to the element symbol, it means there are anumber of those elements combined, such as Fe2 O3 there are two ironmolecules and 3 oxygen molecules combined.. Therefore: 4Fe + 3O2 --> 2Fe2O3
What is the oxidation number of iron(II) oxide?
I am going to assume you meant ferrous oxide. Ferrous oxide is also known as Iron(II) oxide and has the formula unit FeO. The oxidation number of iron in iron(II) oxide is +2.
What are the differences between iron metal and compounds containing iron?
Iron is a chemical element; iron compounds contain in the molecule iron but also other elements.
What 2 things make iron oxide?
Iron oxide is a chemical compound made of iron and oxygen. It exists in two main forms: Fe2O3 (iron(III) oxide, or hematite) and Fe3O4 (iron(II,III) oxide, or magnetite).
Where can you buy small amounts of ferous oxide?
Iron(II) oxide, also known as ferrous oxide or informally as iron monoxide, is one of the iron oxides. It is a black-colored powder with the chemical formula FeO. It consists of the chemical element iron in the oxidation state of 2 bonded to oxygen. Its mineral form is known aswüstite. Iron(II) oxide should not be confused with rust, which usually consists of hydrated iron(III) oxide (ferric oxide). The term may be used more loosely for a non-stoichiometric compound as the ratio of the elements iron and oxygen can vary; samples are typically iron deficient with compositions ranging from Fe0.84O to Fe0.95O.[2]
