3. What typically happens if a complex mixture is analyzed using a constant, low column temperature in gas-liquid chromatography?(A) All peaks become sharper(B) High-boiling analytes may not elute or may produce very broad peaks(C) Low-boiling analytes will not elute(D) The detector stops functioning

4. When light enters glass from air, which property of the radiation remains constant?(A) Velocity(B) Wavelength(C) Frequency(D) All of the above

5. Why is population inversion necessary for laser action?(A) It ensures absorption dominates over emission(B) It allows spontaneous emission to exceed stimulated emission(C) It increases the frequency of the emitted photons(D) It ensures more populations are available for stimulated emission than for absorption

9. Which statement best explains why a bathochromic shift occurs for a $\pi \rightarrow \pi^{*}$ transition when solvent polarity increases?(A) Polar solvents destabilize both $\pi$ and $\pi^{*}$ states equally(B) The ground state $(\pi)$ is more polar and becomes more stabilized(C) The excited state $(\pi^{*})$ is more polar and becomes more stabilized(D) Polar solvents increase the energy gap between $\pi$ and $\pi^{*}$

10. Which of the following statements about a quadrupole mass analyzer is TRUE?(A) A quadrupole mass filter generally offers low-to-moderate resolving power, typically around unit mass resolution.(B) A quadrupole mass analyzer routinely achieves ultrahigh resolving power exceeding 100,000.(C) Quadrupole mass analyzers surpass FT-ICR and Orbitrap instruments in mass resolution.(D) A standard quadrupole mass analyzer is designed to measure ions with extremely high $m/z$ values (e.g., $>10,000$) without special modifications.
