Answered by DrBob222
None of the first four are single displacement. Here is how you tell.
synthesis:
A + B ==> AB

single displacement:
A + BC ==> AC + B

double displacement:
AB + CD ==> AD + CB

decomposition:
the opposite of synthesis.
AB ==> A + B

Follow these four examples to do all of those you list. Ask questions about what you have trouble with but be specific about each as to what you don't understand.
