Explosives, Hazard Class 1
the same when separated
Phosphorus itself is not explosive, but certain forms of phosphorus can be highly reactive or flammable. White phosphorus, for example, can ignite spontaneously in air and is used in incendiary weapons. Red phosphorus, on the other hand, is not as reactive and is commonly used in matches and other products.
organic peroxides
Yes all group one elements (alkali metals) are explosive when they come into contact with water.
A good explosive should have an explosive base that is either solid or liquid. It should also have a long ignition line.
People who try to find answers to the Explosive Ordinance Reconnaissance assignment will not find them via the internet. Instructors for the course should be able to take some time to go over the material with the student.
To study for the series 7 classes, you should purchase preparation material from companies such as Kaplan or Manhattan Review. Or you can check the library.
Francium is the largest alkali metal, but it is not the largest or most reactive metal overall. It is highly reactive due to its position on the periodic table, which means it will react violently with water and air. However, there are other metals that are more reactive than francium, such as cesium and potassium.
There are several classes of hazardous material. Miscellaneous hazardous material belongs to hazard class 9, and appropriate labeling and handling should adhere to the Hazmat shipping procedures.
Not sure what a "colly" detonator is, but if it contains any explosive material in itself, it should be good for about ten years in prison.
Any powdered organic material, when mixed with large volumes of air, CAN explode. It is very rapid combustion. In 2008, anexplosion was triggered by powdered sugar that killed 14 people and injured 36. However, as an explosives engineer, nutmeg would not be my first choice for an explosive.
