possible answers
sample u sample x sample w sample y sample z

Explanation:

To solve this, we first recall the definitions:

• Mixture: Contains two or more different substances (elements or compounds) not chemically combined.
• Compound: A substance with two or more different elements chemically bonded in a fixed ratio.

Analyzing each sample:

• Sample X: Contains different types of molecules (or atoms) and individual atoms, so it’s a mixture (multiple substances, not bonded).
• Sample Y: Molecules with two different atoms (e.g., black and white) bonded—this is a compound.
• Sample W: Molecules with the same type of atoms (all black)—this is an element (not a mixture or compound here, but we focus on mixture/compound).
• Sample Z: Contains two types of atoms (white and black) as separate groups—mixture (different substances, not bonded).
• Sample U: Molecules with three atoms (two white, one black) in a fixed ratio—compound.

Sorting:

• Mixtures: Samples with multiple unbonded substances. So Sample X (different molecules/atoms) and Sample Z (separate groups of atoms) are mixtures.
• Compounds: Samples with bonded different elements. So Sample Y (two-atom molecules) and Sample U (three-atom molecules) are compounds.

Answer:

Mixture(s):

• Sample X
• Sample Z

Compound(s):

• Sample Y
• Sample U

(Note: If the task was to drag and drop, the mixtures are X and Z; compounds are Y and U.)
