Chapter 19.2, Problem 15R

To determine

Whether zinc will displace gold in a chemical reaction or not.

To explain: the given phenomenon.

Explanation of Solution

Introduction:

The chemical reaction is a process in which the materials are converted to one or more separate compounds, the reactants. The substances are either compounds or chemical elements.

A reaction is which one element replaces another element, and then it is known as single displacement reaction.

Reactivity of metals in single displacement reaction is,

Zinc > iron > tin > lead > copper >silver > platinum > gold.

In this case, zinc is more active metal than gold. Therefore, zinc will not displace gold in a chemical reaction.

Conclusion:

Hence,zinc won’t displace gold in a chemical reaction.
