Chemical reactions involve changes - changes of reactants into products. Basic chemical reactions can be grouped into categories based on the types of changes that are occuring during the reaction. There are five basic categories - synthesis, decomposition, combustion, single replacement, and double replacement.

There is only one question in this Question Group. But each time the question appears, the ordering of answers is scrambled. Here is the question.
The Question:
Which one these statements describes how to typically tell the difference between a single replacement (SR) reaction and a double replacement (DR) reaction?
An SR reaction involves the reaction of an element with a compound and a DR reaction involves the reaction of two compounds.
An SR reaction involves the reaction of an element with a compound and a DR reaction involves the reaction of two elements.
An SR reaction involves the reaction of two elements and a DR reaction involves the reaction of two compounds.
A DR reaction is twice as long as an SR reaction.
