CHAPTER 1 REVIEW Chemistry 312 Which of the following measurements would be affected by altitude? Weight or Mass Which of the following would not be considered matter: A. B. C. D. atoms heat alloys pudding After extensive experimentation what end result of the scientific method offers an explanation of what occurs in nature. A Law or a Theory Which of the following properties couldn’t you describe quantitatively: Temperature Time Pressure Color What type of matter does jello represent: a. b. c. d. element compound heterogeneous mixture homogeneous mixture What type of matter does Copper I chloride (CuCl) represent: a. b. c. d. element compound heterogeneous mixture homogeneous mixture What type of matter does this granite represent: a. b. c. d. element compound heterogeneous mixture homogeneous mixture Oskar went into the grocery store in June (2011) and saw a shelf piled high with boxes of candy canes that are on sale. Oskar thinks that this is strange and assumes that they are left over from last winter. He grabs one of the boxes and examines it for a sell by date. The date on the box is 11/2011. What is Oskar’s Hypothesis? The candy canes are left over from last year and outdated The observation of this property of matter is always accompanied by a change in the composition of matter? Physical or Chemical What type of change is represented by the freezing of water to form ice? Physical or Chemical What are the three states of matter? Solid, Liquid and Gas Which of the following is not a physical property? Temperature Ability to dissolve Color Ability to rust Which of the following is an extensive property of matter? Attraction to a magnet Temperature Volume Density Which of the following types of matter can be separated by physical change? Elements Compounds Mixtures A solution is another name for: element compound homogeneous mixture heterogeneous mixture What type of matter is oxygen (O2)? element compound homogeneous mixture heterogeneous mixture What separtation technique would be used to separate a heterogeneous mixture containing a solid and a liquid? distillation chromatography filtration crystallization What separtation technique would be used to separate a homogeneous mixture containing a solid and a liquid? distillation chromatography filtration crystallization What technique uses the physical property of boiling point to separate components of a mixture? distillation chromatography filtration crystallization What type of reaction is associated with the absorption of energy? Exothermic or Endothermic According to the Law of Conservation of Mass, what must the mass of CO2 be in the following equation? C6H12O6 + 6O2 6CO2 + 6H2O 54g + 98g = _99g_ + 53g Which of the following is not an indication of a chemical change? formation of a gas change in color formation of a precipitate melting
