Question

homogeneous vs. heterogeneous matter. mixtures are the physical combination of two or more substances. if a mixture is consistent throughout, or it contains only one phase, the mixture is said to be homogenous. another name for a homogenous mixture is a solution. if a mixture is not consistent throughout, or it contains more than one phase, the mixture is said to be heterogeneous. remember that mixtures can be separated by physical means. classify the following substances and mixtures as either homogeneous or heterogeneous. place a check in the correct column. 1. flat soda pop 2. cherry vanilla ice cream 3. italian salad dressing 4. sugar 5. soil 6. aluminum foil 7. black coffee 8. stirred sugar water 9. city air 10. paint (stirred) 11. rubbing alcohol 12. iron 13. beach sand 14. purified air 15. spaghetti sauce label each substance listed below as an element (e), compound (c), heterogeneous mixture (he), or homogeneous mixture (ho) 1. barium (ba) 2. carbon monoxide (co) 3. soil 4. kool - aid 5. brass (cuzn) 6. air 7. vegetable soup 8. carbon (c) 9. baking soda (nahco₃) 10. jello with fruit 11. gold (ag) 12. milk 13. sand 14. orange juice w/o pulp 15. orange juice w/pulp

Explanation:

Step1: Recall definitions

Homogeneous mixtures are consistent throughout or have one - phase. Heterogeneous mixtures are not consistent or have more than one phase. Elements are made of one type of atom, compounds are made of different types of atoms chemically bonded.

Step2: Analyze each substance for first table

• Flat Soda Pop: Homogeneous as dissolved substances are evenly distributed.
• Cherry Vanilla Ice Cream: Heterogeneous due to different components (cherry, vanilla parts).
• Italian Salad Dressing: Heterogeneous as oils and vinegars separate over time.
• Sugar: Compound (not a mixture for this classification in the table context).
• Soil: Heterogeneous with various components like rocks, organic matter.
• Aluminum Foil: Element (not a mixture for this classification in the table context).
• Black Coffee: Homogeneous as solutes are evenly dissolved.
• Stirred Sugar Water: Homogeneous as sugar is dissolved evenly.
• City Air: Homogeneous as gases are well - mixed.
• Paint (stirred): Homogeneous as components are evenly distributed when stirred.
• Rubbing Alcohol: Homogeneous as it is a solution.
• Iron: Element (not a mixture for this classification in the table context).
• Beach Sand: Heterogeneous with different sized particles and materials.
• Purified Air: Homogeneous as gases are uniformly mixed.
• Spaghetti Sauce: Heterogeneous with chunks of vegetables etc.

Step3: Analyze each substance for second table

• Barium (Ba): E (Element)
• Carbon Monoxide (CO): C (Compound)
• Soil: He (Heterogeneous mixture)
• Kool - Aid: Ho (Homogeneous mixture)
• Brass (CuZn): Ho (Homogeneous mixture)
• Air: Ho (Homogeneous mixture)
• Vegetable soup: He (Heterogeneous mixture)
• Carbon (C): E (Element)
• Baking Soda (NaHCO₃): C (Compound)
• Jello with fruit: He (Heterogeneous mixture)
• Gold (Au, not Ag as Ag is silver, but assuming gold is meant): E (Element)
• Milk: Ho (Homogeneous mixture)
• Sand: He (Heterogeneous mixture)
• Orange juice w/o pulp: Ho (Homogeneous mixture)
• Orange juice w/pulp: He (Heterogeneous mixture)

Answer:

First table:

1. Homogeneous
2. Heterogeneous
3. Heterogeneous
4. N/A (not a mixture for this classification)
5. Heterogeneous
6. N/A (not a mixture for this classification)
7. Homogeneous
8. Homogeneous
9. Homogeneous
10. Homogeneous
11. Homogeneous
12. N/A (not a mixture for this classification)
13. Heterogeneous
14. Homogeneous
15. Heterogeneous

Second table:

1. E
2. C
3. He
4. Ho
5. Ho
6. Ho
7. He
8. E
9. C
10. He
11. E
12. Ho
13. He
14. Ho
15. He
