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. (d)

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, while no reaction occurs if the reverse is attempted.

Single Replacement Reactions

Single replacement reactions occur when one element replaces another in a compound. In the context of the activity series, this type of reaction can be predicted by comparing the reactivity of the metals involved. If the free metal is more reactive than the metal in the compound, a reaction will occur; otherwise, no reaction (NR) will take place.

Predicting Chemical Reactions

Predicting chemical reactions involves using established rules and series, such as the activity series, to determine the outcomes of reactions. In this case, understanding the relative reactivity of metals allows chemists to foresee whether a reaction will occur or if the reactants will remain unchanged. This predictive ability is crucial for planning experiments and understanding chemical behavior.
