2. What types of questions can be answered through science, and what questions are beyond the
boundaries of science? Be specific and give examples to support your answer.
26. Describe Rutherford’s gold foil experiment and how the experimental results led to specific changes
in the accepted model of the atom. Be sure to include a description of the atomic model that was
accepted by the scientific community before this experiment as well as the atomic model that was
accepted after this experiment.
54. Write the complete balanced equation for the reaction between AlF3 and CaO.
57. Write the complete balanced equation for the reaction that occurs when C6 H6 combusts in O2.
61. If 7.65 grams of iron (III) oxide react with 6.85 grams of carbon monoxide to produce 5.10 g of
pure iron, what are the theoretical yield and percent yield of this reaction? Be sure to show the work
that you did to solve this problem.
unbalanced equation: Fe2O3 + CO Fe + CO2 (4 points)
