Labels: Army Regulation, Army Reserve, DD214, service, Soldier. I agree that there is a need for a reserve/guard version of a DD214. For my 27 years of Navy service, all I have is a letter transferring me to the Retired Reserve.
6 Main Types of Chemical Reactions. 1  synthesis reaction. 2  decomposition reaction. 3  single displacement reaction. 4  double displacement reaction. 5  combustion reaction. 6  acid-base reaction.
Types of Chemical Reactions. Doing chemical reactions is the main focus of chemistry because that's where the action is. That's when something gets made, changed, or destroyed. So a lot of emphasis is placed on chemical reactions. Chemical reactions can be understood by these three areas of focus. A reaction is basically shuffling around the building blocks of chemistry (atoms/ions/molecules/electrons). Force & energy is what decides if the reaction occurs and how fast.
