CS-TG-QR218X-01 Sample Test Questions for CSET: Science Subtest II: Chemistry Below is a set of multiple-choice questions and constructed-response questions that are similar to the questions you will see on CSET: Science Subtest II: Chemistry. You are encouraged to respond to the questions without looking at the responses provided in the next section. Record your responses on a sheet of paper and compare them with the provided responses. Scientific calculators will be provided for the examinees taking Science Subtest I: General Science, as well asthe specialty subtests of Life Sciences, Chemistry, Earth and Space Sciences, and Physics. Refer to the California Educator Credentialing Examinations website for a list of the calculator models that may be provided. Directions for the use of the calculator will not be provided at the test administration. You will not be allowed to use your own calculator for CSET: Science subtests. Period 1 Period 2 Period 3 Period 4 Period 5 Period 6 Period 7 1. The bright-line spectrum of the hydrogen atom is not continuous because electron transitions: A. involve discrete amounts of energy. B. always involve electron pairs. C. are forbidden by the quantum model. D. involve random amounts of energy. 2. Which of the following statements about the properties of elements in the periodic table is generally true? A. Elements in the same period of the periodic table have the same atomic radius because they have the same number of orbitals in their electron configuration. B. Elements in Group 1 (1A) and Group 3 (3B) have similar chemical properties because they have the same number of valence electrons. C. Moving down the periodic table, the ionization energies of the elements within a group increase asthe number of orbitals in their electron configurations increases. D. Elements in the same group of the periodic table have similar chemical properties because they have the same number of valence electrons. 3. A sample of N2 occupies a volume of 2.50 L at –120°C. To which of the following approximate temperatures should the gas be heated in order to double the volume of the gas without changing its pressure? A. –240°C B. –60°C C. 33°C D. 306°C 4. Use the graph below to answer the question that follows. Which of the lines in the graph above represents the general relationship between solubility and solution temperature for most soluble solids dissolved in water? A. line 1 B. line 2 C. line 3 D. line 4 5. Thyroid cancer can be treated by giving the patient radioactive iodine-131. Iodine-131 accumulates exclusively in the thyroid gland, thus exposing the cancerous cells to the radiation. If a patient is given a 1.0 g dose of iodine-131 and 0.0625 g remains after 32 days, what is the half-life of iodine-131? A. 2 days B. 8 days C. 17 days D. 30 days 6. Use the information below to answer the question that follows. The graph above shows the energy profile for the given reaction. Which of the following actions will result in the new pathway illustrated on the graph? A. adding a catalyst B. adding Br – C. adding OH– D. increasing the temperature 7. Which of the following is the correct Lewis electron dot structure for CCl4? A. B. C. D. 8. According to the valence shell electron pair
