What are your thoughts? We are here to help you once you come to an answer, however, we cannot do your homework for you.

If we do this, you will not learn it. Therefore you will fail your test. You must do the work yourself and we will guide you in the right direction once you come to an answer.

I am speaking from experience. I went through chemistry 2 semesters ago.

There is no such thing as double replacement or single replacement. They are called double displacement and single displacement.

Your answers would be easily answered if you knew what each one was so here is a short summary.

Double Displacement
AB + CD ----> AD + CB

Single Displacement
A + BC ----> AC + B

Decomposition
AB ----> A + B

Synthesis
A + B ----> AB


Now that you know what each one does all you have to do is write the equation of each of your quesitons and check which one it is using this guideline.
