20 questions
Question 1: The Spinsolve NMR spectrometer, as depicted in the study materials, is a compact device.
A. Ano
B. Ne
Explanation: The images associated with the 'Spinsolve' section (img-19.jpeg, img-20.jpeg, img-21.jpeg) clearly show a compact, benchtop instrument, indicating it is a small device.
Question 2: The provided materials explicitly detail the operating principles of superconducting magnets used in NMR spectrometers.
A. Ano
B. Ne
Explanation: The study materials show images of superconducting magnets and label them as such, but they do not provide any explicit details or descriptions of their operating principles.
Question 3: The external magnetic field causes spinning protons to stop acting like bar magnets.
A. Ano
B. Ne
Explanation: The study materials explicitly state, 'When placed in an external field, spinning protons act like bar magnets.' This indicates that the external field causes them to act like bar magnets, rather than stopping them from doing so.
Question 4: The 850 MHz NMR spectrometer could be housed in a typical laboratory setting without the need for a specially constructed building.
A. Ano
B. Ne
Explanation: The study materials explicitly state, 'Se necesito construir este edificio para albergar el equipo de 850 MHz' (A building had to be constructed to house the 850 MHz equipment), indicating that it required a custom-built facility rather than fitting into a typical laboratory.
Question 5: The 'NMR 300' designation refers to a spectrometer measured in Megahertz (MHz).
A. Ano
B. Ne
Explanation: The study materials directly present 'NMR 300' followed by 'MHz' on the same slide, indicating that 'MHz' is the unit associated with the 'NMR 300' spectrometer.
