Q: Diphenylamine acts as a stabilizer for certain types of what? Read this paragraph and choose the correct option from the provided answers: Amines serve a wide variety of uses. Diphenylamine acts as a stabilizer for certain types of explosives. Amines are found as components in some lubricating materials, in developers, and are a part of waterproofing textiles. Some amines, such as novocaine, are used as anesthetics. Many pharmaceutical compounds contain amines, including 8 of the 10 most prescribed medications in 2012. Choices: - toxins - enzymes - proteins - explosives A:
**Answer**
explosives

Q: Because of the wave character of matter, the idea of well-defined orbits gives way to a model in which there is a cloud of what? Read this paragraph and choose the correct option from the provided answers: Because of the wave character of matter, the idea of well-defined orbits gives way to a model in which there is a cloud of probability, consistent with Heisenberg's uncertainty principle. Figure 30.48 shows how this applies to the ground state of hydrogen. If you try to follow the electron in some well-defined orbit using a probe that has a small enough wavelength to get some details, you will instead knock the electron out of its orbit. Each measurement of the electron's position will find it to be in a definite location somewhere near the nucleus. Repeated measurements reveal a cloud of probability like that in the figure, with each speck the location determined by a single measurement. There is not a well-defined, circular-orbit type of distribution. Nature again proves to be different on a small scale than on a macroscopic scale. Choices: - particles - mutation - chaos - probability A:
**Answer**
probability

Q: Vibrating electric and magnetic fields make up what kinds of waves? Read this paragraph and choose the correct option from the provided answers: What do these two photos have in common? They both represent electromagnetic waves. These are waves that consist of vibrating electric and magnetic fields. They transmit energy through matter or across space. Some electromagnetic waves are generally harmless. The light we use to see is a good example. Other electromagnetic waves can be very harmful and care must be taken to avoid too much exposure to them. X rays are a familiar example. Why do electromagnetic waves vary in these ways? It depends on their properties. Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency. Choices: - seismic - eletrical - mechanical - electromagnetic A:
**Answer**
electromagnetic
