Matter can be classified by analyzing its composition as it is shown in the diagram. Steel is a material that contains two elements: iron (Fe) and carbon (C). Two different samples of steel have different quantities of these two elements, but both have uniform composition. Using the diagram above, how would you classify steel?
As pure substance, because it has uniform composition and it is a compound
As a heterogeneous mixture, because is formed by two different elements
As a homogeneous mixture, because is formed by two different elements and it is uniform
As pure substance, because different samples have different composition
