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. (a)

Verified step by step guidance

1. Step 1: Look up the activity series of metals in Table 4.5. The activity series is a list of metals ranked in order of decreasing reactivity. A metal can displace any other metal below it in the series from a solution of its salts.
2. Step 2: Identify the metals involved in the reaction. The metal in the reactant (the substance that is being reacted) is trying to displace the metal in the compound on the other side of the equation.
3. Step 3: Compare the positions of the two metals in the activity series. If the metal in the reactant is higher in the series (more reactive) than the metal in the compound, then a reaction will occur. The more reactive metal will displace the less reactive metal in the compound.
4. Step 4: Write the products of the reaction. The more reactive metal will take the place of the less reactive metal in the compound, forming a new compound. The less reactive metal will be left on its own.
5. Step 5: If the metal in the reactant is not higher in the series (less reactive) than the metal in the compound, then no reaction will occur. Write NR for no reaction.

Key Concepts

Activity Series of Metals

The activity series of metals is a list that ranks metals based on their reactivity, from most reactive to least reactive. It 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. This type of reaction is often seen with metals and is influenced by the relative reactivity of the metals involved. Understanding this concept is crucial for predicting the outcome of reactions based on the activity series, as it determines whether a reaction will take place or not.

No Reaction (NR)

In the context of chemical reactions, 'No Reaction' (NR) indicates that the proposed reaction does not occur. This can happen when a less reactive metal attempts to displace a more reactive metal from its compound, as dictated by the activity series. Recognizing when NR applies is essential for accurately predicting the outcomes of reactions involving metals.
