  • In the following scenario, identify which of the statements represents a theory, law, or hypothesis. (a) A student exploring the properties of gases proposes that is she decreases the volume of a sample of gas then the pressure exerted by the sample will increase (b) Many scientists over time have conducted similar experiments and have concluded that pressure and volume are inversely proportional. (c) She proposes that the reason this occurs is that if the volume is decreased, more molecules will collide with a given area of the container walls, causing the pressure to be greater.
    Distinguish precisely and in scientific terms the differences among items in the following groups. a Macroscopic matter, microscopic matter, particulate matter b Physical change, physical property, chemical change, chemical property c Gases, liquids, solids d Element, compound e Atom, molecule f Pure substance, mixture g Homogeneous matter, heterogeneous matter h Reactant, product i Exothermic change, endothermic change j Potential energy, Kinetic energy
    Which of the following represent physical properties or changes, and which represent chemical properties or changes? You curl your hair with a curling iron. You curl your hair by getting a “permanent wave” at the hair salon. Ice on your sidewalk melts when you put salt on it. A glass of water evaporates overnight when it is left on the bedside table. Your steak chars if the skillet is too hot. Alcohol feels cool when it is spilled on the skin. Alcohol ignites when a flame is brought near it. Baking powder causes biscuits to rise.
  • Physical and Chemical Changes Say you are presented with two beakers, beaker A and beaker B, each containing a white, powdery compound. a From your initial observations, you suspect that the two beakers contain the same compound. Describe, in general terms, some experiments in a laboratory that you could do to help prove or disprove that the beakers contain the same compound. b Would it be easier to prove that the compounds are the same or to prove that they are different? Explain your reasoning. c Which of the experiments that you listed above are the most convincing in determining whether the compounds are the same? Justify your answer. d A friend states that the best experiment for determining whether the compounds are the same is to see if they both dissolve in water. He proceeds to take 10.0 g of each compound and places them in separate beakers, each containing 100 mL of water. Both compounds completely dissolve. He then states, Since the same amount of both substances dissolved in the same volume of water, they must both have the same chemical composition. Is he justified in making this claim? Why or why not?
    Which of the following are elements, and which are compounds? a NaOH; b BaCl2; c He; d Ag; e Fe2O3.
    Consider the sample of matter in the illustration below. Answer each question independently and explain your answers. a Is the sample homogenous or heterogeneous? b Is the sample a pure substance or a mixture? c Are the particles elements or compounds? d Is the sample a gas, a liquid, or a solid?
