# Answer: D. Compound

### Tree Map (Classifying Matter) Solutions:

#### 1.
# Explanation:
## Step1: Recall matter classification.
Matter is classified into Pure Substances and Mixtures. The first branch of "Classifying Matter" should be "Pure Substances" (since the other is "Mixtures" at 18).
# Answer: Pure Substances

#### 18.
# Explanation:
## Step1: Recall matter classification.
The other main branch of matter classification (opposite to Pure Substances) is Mixtures.
# Answer: Mixtures

#### Element (2,3,4,5,6):
# Explanation:
## Step1: Identify elements from the word bank.
Elements are substances with one kind of particle (atom). From the word bank: Sodium (Na), Helium (He), Chlorine (Cl) are elements. Also, "one kind of particle" and "Atom" relate to elements. Let's fill:
2. Sodium (Na)
3. Helium (He)
4. Chlorine (Cl)
5. (can be "Atom" as the smallest unit of element)
6. (can be "one kind of particle" as a property of element)
# Answer:
2. Sodium (Na)
3. Helium (He)
4. Chlorine (Cl)
5. Atom
6. one kind of particle

#### Compound (7,8,9,10,11,12):
# Explanation:
## Step1: Identify compounds from the word bank.
Compounds are pure substances with chemically combined elements (molecules or formula units). From the word bank: Salt (NaCl), Water (H₂O), Sugar (C₆H₁₂O₆) are compounds. Also, "chemically combined" and "Molecule" (for molecular compounds) relate.
7. (already labeled as Compound, so the property: "chemically combined")
8. Salt (NaCl)
9. Water (H₂O)
10. Sugar (C₆H₁₂O₆)
11. (property: "Molecule" for molecular compounds)
12. (another property: "one kind of particle" – wait, no, pure substances (elements and compounds) have one kind of particle. So maybe "one kind of particle" is for pure substances, but compounds are pure, so:
Wait, re - evaluate:
Pure Substances (1) split into Element and Compound (7).
Element: made of atoms, one kind of particle.
Compound: made of molecules (or ions) of the compound, chemically combined elements, one kind of particle (the compound's particle).
So:
7. Compound (label)
8. Salt (NaCl)
9. Water (H₂O)
10. Sugar (C₆H₁₂O₆)
11. Molecule (smallest unit of compound)
12. chemically combined (how elements are in compound)
# Answer:
7. Compound (label)
8. Salt (NaCl)
9. Water (H₂O)
10. Sugar (C₆H₁₂O₆)
11. Molecule
12. chemically combined

#### Mixtures (13,14,15,16,17,19,20,21,22):
# Explanation:
## Step1: Recall mixture types.
Mixtures split into Homogeneous (uniform appearance, not see individual parts) and Heterogeneous (can see individual parts).
Homogeneous mixtures (13): examples from word bank: Kool - Aid, Salt Water, Air, Salad? No, Salad is heterogeneous. Wait, word bank has: Kool - Aid, Salt Water, Air (homogeneous), Pizza, Salad (heterogeneous).
13. Homogeneous (label, since the other is heterogeneous)
14. Salt Water (homogeneous mixture)
15. Kool - Aid (homogeneous mixture)
16. Air (homogeneous mixture)
17. (property: "uniform appearance", "not see individual parts")
Heterogeneous (label at the end, and 19 - 22):
19. Pizza (heterogeneous mixture)
20. Salad (heterogeneous mixture)
21. (property: "heterogeneous" – wait, no, the label is heterogeneous, and examples are Pizza, Salad, maybe others. Also, property: "not chemically combined" (mixtures have components not chemically combined), "see individual parts".
So:
13. Homogeneous
14. Salt Water
15. Kool - Aid
16. Air
17. uniform appearance (or "not see individual parts")
19. Pizza
20. Salad
21. see individual parts
22. not chemically combined

### Drawing Section (Using Circles):

#### Element:
# Explanation:
## Step1: Represent an element.
An element is made of only one type of atom. Draw several identical circles (e.g., 3 - 4 circles of the same size and color) in the "Element" box.
#### Compound:
# Explanation:
## Step1: Represent a compound.
A compound is made of molecules (or formula units) with two or more different atoms. For example, for water (H₂O), draw molecules with one larger circle (O) and two smaller circles (H) bonded together (e.g., draw 2 - 3 H₂O molecules: each as O - H - H, with O and H circles of different sizes).
#### Mixture of Elements:
# Explanation:
## Step1: Represent a mixture of elements.
Draw two different types of circles (e.g., circles of different colors/sizes) mixed together, not bonded. For example, circles for hydrogen (H) and oxygen (O) atoms mixed (not as H₂O, just separate H and O circles).
#### Mixture of Compounds:
# Explanation:
## Step1: Represent a mixture of compounds.
Draw molecules of two different compounds. For example, draw water (H₂O) molecules and sugar (C₆H₁₂O₆) molecules (different - looking molecules, e.g., H₂O as O - H - H and sugar as a more complex shape with C, H, O circles) mixed together.
#### Mixture of Elements and Compounds:
# Explanation:
## Step1: Represent a mixture of elements and compounds.
Draw molecules of a compound (e.g., H₂O) and atoms of an element (e.g., O atoms) mixed together. So include both H₂O molecules and O circles in the box.
