Question

classify each type of matter as an element, a compound, a heterogeneous mixture, or a homogeneous mixture. drag each item to the appropriate bin. view available hint(s)

Explanation:

• Element: A pure substance made of only one kind of atom. Aluminum (Al), gold (Au), and barium (Ba) are elements as they consist of only one type of atom.
• Compound: A pure substance formed when two or more elements chemically combine. Carbon monoxide (CO) and sugar (e.g., sucrose \(C_{12}H_{22}O_{11}\)) are compounds as they have a fixed ratio of different elements.
• Heterogeneous mixture: A mixture where the components are not uniformly distributed. Soil has various components (minerals, organic matter, etc.) that are not evenly mixed, and orange juice with pulp has distinct parts (liquid and solid pulp).
• Homogeneous mixture: A mixture with a uniform composition throughout. Air (a mixture of gases like \(N_2\), \(O_2\), \(CO_2\) etc. evenly distributed), salt - water (salt dissolved uniformly in water), acetone (a pure - looking liquid in the context of common mixtures, often considered a homogeneous phase), and hot coffee (components like water, caffeine, etc. uniformly mixed) are homogeneous mixtures.

Answer:

• Element: aluminum, gold, barium
• Compound: carbon monoxide, sugar
• Heterogeneous mixture: soil, orange juice with pulp
• Homogeneous mixture: air, salt water, acetone, hot coffee
