Studdy Solution
STEP 1
Assumptions1. Hot coffee is a mixture of coffee and water, possibly with sugar and/or milk.
. Salt water is a mixture of salt (sodium chloride) and water.
3. Aluminum is a chemical element.
4. Gold is a chemical element.
5. Orange juice with pulp is a mixture of water, sugars, and orange pulp.
6. Magnesium is a chemical element.
7. Carbon dioxide is a compound of carbon and oxygen.
8. Air is a mixture of nitrogen, oxygen, and small amounts of other gases.
9. Sugar is a compound of carbon, hydrogen, and oxygen.
10.oluene is a compound of carbon and hydrogen.
11. Soil is a mixture of organic matter, minerals, gases, liquids, and organisms.
STEP 2
Classify each type of matter based on the definitions of element, compound, heterogeneous mixture, and homogeneous mixture.
1. An element is a substance that cannot be broken down into simpler substances by chemical means.
2. A compound is a substance formed when two or more chemical elements are chemically bonded together.
. A heterogeneous mixture is a mixture that composes of components that aren’t uniform or they have localized regions with different properties. Different samples from the mixture are not identical to each other.
4. A homogeneous mixture is a mixture which has uniform composition and properties throughout. Any given sample of the mixture will have the same properties as any other sample.
STEP 3
Classify each type of matter.
1. Hot coffee is a homogeneous mixture.
2. Salt water is a homogeneous mixture.
3. Aluminum is an element.
. Gold is an element.
5. Orange juice with pulp is a heterogeneous mixture.
6. Magnesium is an element.
7. Carbon dioxide is a compound.
8. Air is a homogeneous mixture.
9. Sugar is a compound.
10.oluene is a compound.
11. Soil is a heterogeneous mixture.
