Pyrite is FeS. When exposed to water and oxygen in the air, a chemical reaction occurs - forming iron hydroxide (rust) and sulfuric acid. Here is the reaction:
FeS2 + 3.75O2 + 3.5H20 = Fe(OH)3 + 2H2SO4
Rust is a compound, not an element. It is primarily composed of iron oxide, formed when iron reacts with oxygen in the presence of water or moisture. Iron, one of the elements, combines with oxygen, another element, to create rust.
Rust is an iron oxide compound. There are several different iron oxides that make up rust.
Rust is most of all 'metal oxide' which is chemically formed by reaction of certain metals (not all) with oxygen (gas, 20% in air)
Iron is the most common element that erodes to form rust, which is composed of iron oxide. When iron comes into contact with water and oxygen, a chemical reaction occurs that causes the iron to corrode and form rust.
The term "rust" technically applies only to iron oxides and its variations, so the element carbon cannot rust.
You just smelt out the iron and collect both the iron and sulfur remaining, or by weathering the pyrite you can rust away the iron and use water to collect the sulfur as sulfuric acid.
Rust is a COMPOUND. rust is a element you stupid fool suk my prik
iron (i.e., pure) is a metal / element in the periodic table, but types of iron are compounds like wrought iron, pig iron cast iron., etc.
iron is one anything that can be oxidized will rust
No, rust is specific to the element Iron.
The element required for an iron kettle to rust is oxygen.
Rust is a compound, not an element. It is primarily composed of iron oxide, formed when iron reacts with oxygen in the presence of water or moisture. Iron, one of the elements, combines with oxygen, another element, to create rust.
Because of the pressure and time used to create natural pyrite, more crystals develop, giving it that shiny, crystalline look, whereas man made is created in such a short amount of time that there isn't a lot of gold, and once it dries, many colors show after rust appears on the pyrite.
Rust is an iron oxide compound. There are several different iron oxides that make up rust.
i know a penny can rust, but im not sure what makes a peny rust! i, too, hope to find out!
it dos'nt it makes rust
I am quite sure that rust is a chemical change. Rust is caused when oxygen atoms begin bonding with the iron in the nail, which makes it a compound instead of a pure element.
