Answer the following question given this paragraph: The oxidation of an alcohol can produce either an aldehyde or a ketone. Ethanol can be oxidized in the laboratory through a heating process combined with the addition of an oxidizing agent such as the dichromate ion, which catalyzes the reaction in an acidic solution. The reaction produces the aldehyde ethanal (acetaldehyde). Q: The oxidation of an alcohol can produce either an aldehyde or what? Choices: - enzyme - amine - ester - ketone A:
ketone

Answer the following question given this paragraph: Meters, such as those in analog fuel gauges on a car, are another common application of magnetic torque on a current-carrying loop. Figure 22.37 shows that a meter is very similar in construction to a motor. The meter in the figure has its magnets shaped to limit the effect of by making B perpendicular to the loop over a large angular range. Thus the torque is proportional to I and not. Q: Meters, such as those in analog fuel gauges on a car, are a common application of magnetic torque on a current-carrying what? Choices: - circuit - dial - arc - loop A:
(Answer)
loop
