Question

1. made up of two types of matter that can be physically separated
2. mixture
3. heterogeneous mixture
4. matter
5. element
6. homogeneous mixture
7. compound

a. divide by 1000. this is a standard metric prefix.
b. the standard unit of mass is very small.
c. the standard metric unit of length equal to 3.3 feet.
d. the standard metric unit of volume. used to measure liquids.
e. means divide by 100. key is in the word centi-
f. prefix that means one - thousandth.
list heterogeneous and homogenous mixtures for.
mixture\theterogenous\thomogenous
jello\tfruit cup\taverage jello
ice cream\toreo\tvanilla
soup\t\tchicken broth
mark these as elements (e) or not (n).
water (h₂o)
hydrogen (h)
helium (he)

Explanation:

1. Mixture: A mixture is made up of two types of matter that can be physically separated (a).
2. Heterogeneous Mixture: Two samples might not be the same (b). For example, a fruit - cup or an Oreo in ice - cream are heterogeneous mixtures as different parts have different compositions.
3. Homogeneous Mixture: Two samples will have the same makeup (c). Examples like average jello, vanilla ice - cream, and chicken broth are homogeneous mixtures as they have uniform composition throughout.
4. Matter: A classification of anything that has mass and takes up space (g).
5. Element: Has only one kind of atom (d). Hydrogen (H) and Helium (He) are elements.
6. Compound: Contains two kinds of atoms that cannot be physically separated (e). Water ($H_2O$) is a compound.
7. Metric Units:

• Meter: Standard metric unit of length. To convert to kilometers, divide by 1000 (a).
• Kilo -: Prefix meaning 1000 times the base unit.
• Gram: Standard metric unit of mass.
• Milli -: Prefix meaning divide by 1000.
• Centi -: Prefix meaning divide by 100.
• Liter: Standard metric unit of volume used to measure liquids.

Answer:

1. Mixture - a
2. Heterogeneous Mixture - b
3. Homogeneous Mixture - c
4. Matter - g
5. Element - d
6. Compound - e
7. Meter - a
8. Kilo - (no specific match in given right - hand side descriptions but it's a prefix)
9. Gram - (no specific match in given right - hand side descriptions but it's a unit)
10. Milli - (no specific match in given right - hand side descriptions but it's a prefix)
11. Centi - (no specific match in given right - hand side descriptions but it's a prefix)
12. Liter - d

Water ($H_2O$) - Compound
Hydrogen (H) - Element
Helium (He) - Element
