Explanation:

Step1: Recall Mixture Definition

A mixture is a combination of two or more substances that are physically combined, not chemically bonded. So we analyze each option:

• A. Iced tea: Contains water, tea, sugar (maybe), etc. Physically mixed. Mixture.
• B. Salt water: Salt (\(NaCl\)) dissolved in water. Physically mixed. Mixture.
• C. Table sugar: \(C_{12}H_{22}O_{11}\), a pure compound (can be chemically decomposed? Yes, but it's a pure substance, not a mixture).
• D. Orange juice: Contains water, pulp, sugars, etc. Physically mixed. Mixture.
• E. Aluminum oxide: \(Al_2O_3\), a pure compound (can be chemically decomposed? Yes, but pure substance, not mixture).

Step2: Classify Each Example

• Iced tea (A): Mixture (can be physically separated, composition not uniform? Wait, iced tea with ice: ice is water, tea is solution. But even without ice, tea has soluble and maybe insoluble parts? Wait, the flow chart: mixtures are either "Emulsion or Suspension" (non - uniform) or "Solution" (uniform). Salt water is a solution (uniform), iced tea (if with ice, suspension? If just tea, maybe solution or emulsion? But regardless, it's a mixture. Orange juice: has pulp (suspension), so mixture. Table sugar: pure compound (element? No, compound). Aluminum oxide: pure compound.

So mixtures are A (iced tea), B (salt water), D (orange juice). Wait, but let's check the flow chart:

Matter → Can it be physically separated? → Yes (Mixture) or No (Pure Substance).

Pure Substance → Can it be chemically decomposed? → Yes (Compound) or No (Element).

Mixture → Is composition same throughout? → Yes (Solution) or No (Emulsion/Suspension).

So:

• Iced tea: Mixture (can be physically separated), composition not same throughout (has ice, tea, maybe sugar) → Emulsion/Suspension? Or if iced tea is just tea (no ice), maybe solution? But still a mixture.
• Salt water: Mixture, composition same throughout (solution).
• Table sugar: Pure Substance (compound, since \(C_{12}H_{22}O_{11}\) can be decomposed into C, H, O).
• Orange juice: Mixture, composition not same throughout (has pulp) → Emulsion/Suspension.
• Aluminum oxide: Pure Substance (compound, \(Al_2O_3\) can be decomposed into Al and O).

So the mixtures are A, B, D. Wait, but the options are A. iced tea, B. salt water, C. table sugar, D. orange juice, E. aluminum oxide.

So the correct examples of mixtures are A, B, D.

Answer:

A. iced tea, B. salt water, D. orange juice
