Use the activity series of metals (Table 4.5) to predict the outcome of each of the following reactions. If no reaction occurs, write NR. (b)

Key Concepts

Activity Series of Metals

The activity series of metals is a list that ranks metals based on their reactivity, with the most reactive metals at the top and the least reactive at the bottom. This series helps predict whether a metal will displace another metal in a chemical reaction. For example, a metal higher in the series can displace a metal lower in the series from its compound.

Single Replacement Reactions

Single replacement reactions occur when one element replaces another in a compound. In these reactions, a more reactive metal can displace a less reactive metal from its compound, leading to the formation of a new compound and the release of the less reactive metal. Understanding this type of reaction is essential for predicting outcomes using the activity series.

No Reaction (NR)

In some cases, when two metals are involved in a potential reaction, no reaction (NR) occurs if the more reactive metal is not present to displace the less reactive one. This outcome indicates that the conditions for a single replacement reaction are not met, and thus, the original compounds remain unchanged. Recognizing when NR applies is crucial for accurately predicting reaction outcomes.
