    • Iron is another element classified as a pure substance.
    • Oxygen is categorized as an element and is a pure substance.
    • Water is a compound and a pure substance, made of hydrogen and oxygen.
    • Salt (sodium chloride) is classified as a compound and a pure substance.
    • Sucrose is a compound and also a pure substance.
    • Aluminum is an element designated as a pure substance.
    • Chlorine is classified as an element and a pure substance.

    Mixtures: Homogeneous and Heterogeneous

    • Air is classified as a homogeneous mixture and is considered a solution.
    • Stainless steel is a homogeneous mixture and also classified as a solution.
    • Soft drinks are homogeneous mixtures, specifically solutions.
    • Vinegar is a homogeneous mixture that fits the definition of a solution.
    • Syrup qualifies as a homogeneous mixture and is classified as a solution.
    • Cottage cheese is identified as a heterogeneous mixture.
    • Muddy water is classified as a heterogeneous mixture.
    • Italian dressing is a heterogeneous mixture.
    • Smoke is categorized as a heterogeneous mixture.
    • Granite is another example of a heterogeneous mixture.
    • Blood is classified as a heterogeneous mixture.
    • Wood is identified as a heterogeneous mixture.

    Composition Uniformity

    • Air, stainless steel, soft drinks, vinegar, and syrup all exhibit uniform composition.
    • Cottage cheese, muddy water, Italian dressing, smoke, granite, blood, wood, and dirt have non-uniform composition, highlighting their heterogeneous nature.
