Many explosives are not detectable by x-ray machines, due to their low density. Inspection or bomb sniffing dogs are the only reasonably reliable ways to detect such low density high explosives.

Most common is nitrogen.
hey devil dog, you figure it out
Depends. People that develop explosives are Chemical Engineers. People that design the USE of explosives may be Civil Engineers, or Mining Engineers. However, many everday users of explosives for mining and construction do not have a degree.
In the late 1990s, 101 establishments were in operation in the explosives manufacturing industry.
Software has to be written to run on a particular operating system. While there are lots of programming languages that will run on many operating systems, a compiler or runtime engine has to interpret the programming language and translate it into commands that the operating system understands. The Operating System is the foundation of the building. Applications are the structure built on the foundation.

That depends on where you are and what kind of explosives you make. The ATF redefined the word 'explosives" last year to include several products that were not previously considered explosives. In many places you can make your own black powder, rocket propellants and fuse. Some more powerful "explosives" can be made in very small quantities for use in fireworks, but there are restrictions on the storage of explosives. For more detailed and up to date rules, go to atf.gov.
Primary and secondary explosives. The definitions of these are rather loose, however typically primary explosives will detonate when ignited (example: mercury fulkminate), and secondary explosives require a shockewave to detonate (example: TNT). The most accurate definition is when used in the context of an "explosive train" whereby a fuse ignites the primary high explosive which undergoes deflagration to detonation transition, this detonation produces a shockwave which is used to initiate a secondary high explosive. So explosive compounds are classified into primary or secondary based there primary use.
