What is the chemical formula of Butyric acid?

When iron is mined or otherwise found in nature, it is typically found as a naturally occurring mineral. When iron ore is heated in the presence of a reducing agent such as carbon monoxide, it produces metallic iron. From there, iron is further refined to create an iron-carbon alloy that can be used to make the material we know as steel.
