Study Table 13.1, noting in particular the oxygen balance figures. Predict which energetic is likely to be the largest component of propellant and explain your reasoning. What will be an ideal response?

Hydrogen is billed as "the fuel of the future" for automobiles. A popular misconception, mostly due to films of the Hindenburg disaster, is that cars that store hydrogen as fuel will be more likely to explode in an accident than current cars using gasoline. Why is this a misconception?

Two common solvents used in clandestine drug labs are diethyl ether and acetone. Being less than vigilant in lab and safety practices, clandestine chemists often work with leaky equipment. If a person was brought to the emergency room under suspicious circumstances, where would you predict the burn patterns on their body to be most pronounced if they were injured by a fire/explosion at a clandestine laboratory?

An analyst loads a blood alcohol sample onto an instrument equipped with a single column and FID detector. The run is completed and the analyst recaps the vial and places it on a second headspace unit connected to GC-FID with the confirmation column. What is the problem with this approach?

An analyst prepares a homogenized liver sample by placing a weighed amount in a test tube, adding methanol, and sonicating. The entire extract is placed on a SPE column, extracted, and dried. She then reconstitutes the extract in a known volume of internal standard solution. What is the problem with this approach?

Design a micro-LLE extraction for plasma designed to detect acidic drugs. What will be an ideal response?

If a fuel cell such as shown in Figure 10.17 is used to detect breath alcohol, what other compounds might cause a false positive?

Fentanyl is a powerful synthetic opiate. Based on your findings in the previous question (hint: structure), does this strike you as odd?

If you look up the apparent volume of distribution (Vd) of a few drugs, you will find that many are reported as ranges rather than as a single value. Why?

Some drugs are absorbed as ion pairs, a topic we discussed in Chapter 7 . Explain how this would work and what drugs are most likely to follow this mechanism. What will be an ideal response?
