  3. What is an atom?

  4. The smallest, most basic particle of matter from which all elements are made

  5. How is an element different from a compound?

  6. An element is a pure substance that cannot be broken down, but a compound is a pure substance that is made up of two or more elements

  7. Is orange juice a pure substance or a mixture? Is it a heterogeneous or homogeneous mixture?

  8. No pulp: homogeneous mixturePulp: heterogeneous mixture

  9. List the following terms from most simple to most complex:pure substance, compound, heterogeneous mixture, element, solution, atom

  10. Atom, element, compound, pure substance, solution, heterogeneous mixture

  11. How could you prove to someone that salt water is a solution and not a compound?

  12. Show how to separate the salt from the water

  13. What is matter?

  14. Anything that has mass and takes up space

  15. Name one example of a homogeneous mixture and one example of a heterogeneous mixture.

  16. N2O5 is a compound with how many atoms? How are these atoms connected?

  17. 7 total atomsThey are connected by chemical bonds

  18. How are homogeneous mixtures and heterogeneous mixtures similar? How are they different?

  19. They are similar because they are both combinations of pure substances. They are different because you can see the different parts of the mixture in a heterogeneous mixture.

  20. Draw a picture of what the molecules of a pure substance would look like and what the atoms of a heterogeneous mixture would look like

  21. True or false: In a physical change, matter changes into a new kind of matter.

  22. False. A physical change only changes the form of the matter

  23. Which is an example of a chemical change:a. burning woodb. freezing waterc. bending a paper clip

  24. a. Burning wood

  25. Are the following properties chemical or physical?:A. Flexibility B. Flammability C. Ability to react D. Texture

  26. A/D – PhysicalB/C - Chemical

  27. Name one example of a physical change and one example of a chemical change.

  28. Physical – changes the form of the substanceChemical – changes into a new substance

  29. If I change matter with a chemical change or a physical change, will it have the same mass as it had before the change? Why?

  30. Yes, Law of Conservation of Matter – Matter is neither created nor destroyed

  31. Metal rusting is an example of what kind of change?

  32. Chemical Change

  33. How is a physical property different from a chemical property?

  34. A physical property can be observed without changing the substance into another one. A chemical property is a characteristic that describes a substances ability to change into a different substance.

  35. Explain why a substance changing from a solid to a liquid is not a chemical change. (ex: ice melting)

  36. The substance is the same substance, it is just in a different form

  37. A scientist did an experiment described below:hydrogen + oxygen water + energyThe scientist used 2 grams of hydrogen and 16 grams of oxygen in the reaction. What is the mass of the water produced?

  38. 18 grams

  39. A scientist did an experiment described below:hydrogen + oxygen water + energyThe properties of the water produced by the reaction are: a. different from the properties of H and Ob. the same as the properties of H and Oc. the same properties of H but different from Od. the same properties of O, but different from H

  40. a. Different from the properties of H and O

  41. A rainbow is an example of:what type of energy?Is this type of energy kinetic or potential?

  42. Radiant energyKinetic because the light waves are traveling through space, which means they are in motion

  43. When do you experience radiant energy?

  44. When you use lights, or when you are outside in the sun

  45. Why is play guitar an example of an exothermic change

  46. The mechanical energy of strumming the strings releases sound energy

  47. Name all the types of energy involved in cooking bread. What role does each form or energy play in the process?

  48. Electrical Energy – powers the over Chemical Energy – released when the ingredients combine and react Thermal Energy – given off from the oven helps the bread cook
