Given information
Classify iron as a pure substance or a mixture. If it is a pure substance, classify it as an element or a compound. If it is a mixture, classify it as homogeneous or heterogeneous.
Step-by-step explanation
Step 1.
Compounds are formed when atoms join in simple whole-number ratios.
A pure substance can be either an element that cannot be broken down into simpler substances or a complex made up of two or more components in specific proportions.
A mixture is homogeneous, meaning it has the same composition throughout the solution, or heterogeneous, meaning has different compositions in different areas. The constituent particles of the mixture are distinguishable in the heterogeneous mixture and indistinguishable in the homogeneous mixture.
