1. Single Replacement Reactions

2. Single replacement reactions occur when a single uncombined element replaces another element in a compound. 2

4. The Activity Series allow us to predict whether or not a SR reaction will happen:
If the single element is more active on the chart compared to
the one in the compound, the reaction will happen.
If it is not, then there is no reaction.
