B, D and C E and C B and E A, C, and D None 2. Two or more kinds of matter put together that don't change their physical properties. mixture mass solution matter None 3. Which is not going to help you dissolve a solid in a liquid? stir faster add heat add more liquid make the solid into smaller pieces None 4. Why does oil float on top of water? Oil has a greater density than water. Oil has a greater volume than water. Water has a greater volume than oil. Water has a greater density than oil. None 5. The amount of space something takes up is matter volume density mass None 6. Anything that has mass and takes up space is matter volume density mass None 7. A mixture of two or more kinds of matter evenly spread out and changes the physical properties is mixture solution concentration All of the above. None 8. Manuel stirred 10 grams of salt into 50 mL of water and 10 grams of sand into 50 mL of water. He stirred them both then he let both mixtures sit for 10 minutes. What important difference is observed between these two mixtures? Mixture 1 is a solid and a liquid, but Mixture 2 is not. The salt, sand, and the water do not mix together. Mixture 2 can be separated, but Mixture 1 can not. Salt dissolves in the water but the sand does not. None 9. A magnet would be most useful in separating which of the following mixtures? sand and iron fillings sugar and ice tea rocks and soil salt and water None 10. It's best to use a paper filter to separate salt from water. True or false? True because the salt does not dissolve into the water. False because the salt dissolves into the water. None 11. What is a substance that is dissolved in another substance? solution Solute Solvent Compound None 12. How are mixtures and solutions different form each other? there are no differences once combines chemically the other combines electronically they have more than one elements in them the mixture combines physically and the solution is not easily separated None 13. What does this picture represent? Mixture Compound Solution Element None 14. A combination of particles of one or more substance that are distributed uniformly throughout another substance is a/an Mixture Compound Solution Element None 15. Which of the following is a homogeneous mixture? Sugar Salt Water Sugar water solution None 16. Which of the following is a universal solvent? Vinegar Alcohol Water Olive oil None 17. This type of mixture contains two or more substances that are visibly distinguishable. Homogeneous Heterogeneous Solution Colloids None 18. The image BELOW is an example of a/an Plasma Mixtures Solution Colloids None 19. Milk is a ... Heterogeneous Homogeneous None 20. What is NOT an attribute of a mixture? Mixtures go through a chemical change Mixtures do not go through a chemical change Mixtures can be separated Substances do not lose their physical properties in a mixture None 21. Which of the following in an insoluble substance Alcohol Sand Sugar Salt None 22. Which of the following is a liquid in liquid solution Alcohol and water Water and oil Sugar and water Salt and water None 23. Water and oil is a ... Mixture Solution None 24. What is the difference between glass A substance and glass B substance ? there are no differences Glass B is physically combined and can be easily separated Glass A is chemically combined Glass A is combined physically and can be easily separated None 25. Coke Cola is an example of a Gas and liquid solution Solid and liquid solution Gas and solid solution Gas and gas solution None 26. Flour and water mixed together is best describe as a Saturated Solution Suspension Colloid None 27. Best definition for suspension A suspension is when a solid and liquid chemically combine A suspension is when a solid don't completely dissolve in a liquid A suspension is when a solid dissolves in a liquid but then separates after 5 minutes None of the above None 28. If we keep adding salt to a glass of water stirring it to dissolve and then adding more salt again . What will happen to the solution after a period of time ? It will become hot The water will become very cold after 6 spoons of salt Nothing will happen The solution will become saturated and the salt will stop melt None 29. This is a kind of mixture that has particles that do not completely dissolve and settle down at the bottom. suspension Solution Solvent colloid None 30. When mixtures are combined and left undisturbed, some particles may be suspended. Which of the following mixtures shows suspension? Salt solution Cheese muddy water Fog None 31. Colloid is an example of non-uniform mixture. Which of the following is NOT a colloid? mayonnaise gelatin milk bleach None 32. All the following is true about suspensions EXCEPT Once they settle particles can be seen floating They are homogeneous mixtures Particles can be seen in the mixture with naked eyes They are heterogeneous mixture None 33. Miscible liquids are ones that can mix together . An example is .. Oil and water Alcohol and water Vinegar and oil Gasoline and water None Time's up
