Why can iron sulphide be classified as an element compound or a mixture?
Because in a chemical compound is a chemical bond between the elements. From a mixture of iron and sulfur iron can be separated with a magnet.
Is iron rust a Chemical or physical change?
Chemical change, because it cannot be reversed/ cannot be undone Iron rusting is a chemical change (Oxidization) the elements iron and oxygen form a molecular bond to form a compound known as Iron oxide (Rust). this reaction can be undone as is done with iron ore.
What happens to metals when they combine with nonmetals in the environment?
That depends on the metals and the nonmetals used. Example: iron combines with oxygen to form rust or " iron oxide". A covalent bond of the materials is formed is the simple answer. Chemical bonds involve the exchange or sharing of electrons. Redox reactions occur whenever electrons are exchanged. In a redox reaction, one atom is oxidized, meaning it loses electrons, and another atom is reduced, meaning it gains electrons. When an ionic bond is formed between a metal and a nonmetal, the metal atom is oxidized and the nonmetal atom is reduced.
What happens to the particle in the iron and sulfur reaction?
The particles bond togeter and form Fes :)
What chemical property is responsible for iron rusting?
rust is chemically iron oxide.When it is under moisture(like in rainy season) and it comes in contact with oxygen it reacts with this oxygen to form iron oxide or rust.To prevent iron cmin in contact with oxygen it is painted and passed through processes like galvanization
What happens when iron turns into fe2 plus in a chemical reaction?
it gives two of its electrons away.
Why can iron sulphide be classified as an element compound or a mixture?
Because in a chemical compound is a chemical bond between the elements. From a mixture of iron and sulfur iron can be separated with a magnet.
What type of bond form iron 2 bromide?
Ionic bond. The metal (iron) gives up electrons to the non-metal (bromine.)
What chemical change happens on an iron?
Rusting is the common chemical reaction for iron.
How do you know iron sulphide is not a mixture?
Because in a chemical compound is a chemical bond between the elements. From a mixture of iron and sulfur iron can be separated with a magnet.
How is iron sulphide a compound and not just a mixture of iron and sulfur?
Because in a chemical compound is a chemical bond between the elements. From a mixture of iron and sulfur iron can be separated with a magnet.
Is ions in a bar of pure iron are surrounded by a large number of valence electrons a covalent bond?
Iron has metallic bonds.
Describe why iron filings and sulfur can be classified as element compound or mixture?
Because in a chemical compound is a chemical bond between the elements. From a mixture of iron and sulfur iron can be separated with a magnet.
Why can you pour water but not iron at room temperature?
At room temperature water is a liquid and iron is a solid. That is because the bond between water molecules is much weaker than the bond between iron atoms. The water molecule (H2O) has its own stability, because the oxygen and the hydrogen share electrons, whereas an iron atom shares its valence electrons not within a molecule, but with all the other iron atoms in a given piece of iron, in what is called a metallic bond.
What bond is iron and iron?
It's the Metallic Bonding .The iron atoms form (+ve)ions that are surrounded by a sea of mobile (delocalised) free valence electrons.
How many 3d electrons does an Fe3 plus ion have?
The answer is 3. Fe -> Fe3+ + 3e
What chemical reaction happens when iron combines with oxygen?
rust?
