Label the following reactions as combination, decomposition, displacement, precipitation, or acid-base reaction. Also whether each reaction is a redox or non redox reaction.
A + B ==> AB synthesis
AB + CD ==> AC + BD double replacement
AB ==> A + B decomposition (the reverse of synthesis)
There must be something fundamental going on here. Perhaps I can help if you can be specific about your understanding of this concept.
