Use the reaction that occurs when magnesium burns in oxygen to show how a reaction might be included in more than one category of reaction.
I don't know what the question is getting at? Do you have specific categories from which to choose?
the categories are: synthesis, decomposition, single replacement, double replacement, and combustion.
Mg + O2 ==> MgO which is a synthesis reaction. How you can get a decomposition, sr or dr out of that one reaction I don't know.
