Iron Oxide [Rust] is most often represented as Fe2O3.
FeO2 - Iron oxide
AgO2 is silver oxide. An other more common example of an oxide is iron oxide, FeO2, more commonly known as rust! Most metals are not pure in their natural states, but rather are found in an oxidized state.
salt is not from salt water
Plain salt would mean ordinary table salt, as opposed to flavored salt . There are onion salt, garlic salt, seasoned salt, smoked salt , celery salt, etc. -- none of these would be plain salt.
Talking about Iron. Rust is an oxide of Iron. Basically Iron that rusts has captured Oxygen from the air around it in a chemical reaction - a slow one thankfully! The weight increase is due to the attached Oxygen.
inorganic
yes it is.
Rust.
fe + 2 O ------> FeO2 iron II oxide
Salt peter refers to the compound potassium nitrate or sometimes sodium nitrate. both saltpeter do have a metallic element in their make up however they are not metals any more then Feo2 (rust is a metal).
13 L of FeO2 can be produced from 50.0 L of O2 at STP.
FEO2
FeO2 - Iron oxide
iron and 2 oxygen
Iron Oxide is a solid.
approx. 45.6
FeO2= is a ferric ion where FeO3- is a ferrous ion.
