Solution Steps

Step 1: Identify the Reaction Type

The given chemical equation is:

\[ \mathrm{XY} + \mathrm{WZ} \rightarrow \mathrm{XZ} + \mathrm{WY} \]

In this equation, two compounds, \(\mathrm{XY}\) and \(\mathrm{WZ}\), react to form two new compounds, \(\mathrm{XZ}\) and \(\mathrm{WY}\). This type of reaction involves the exchange of components between the two reactants.

Step 2: Determine the Correct Reaction Type

The options provided are:

  1. Single replacement
  2. Decomposition
  3. Exchange
  4. Combination
  • Single replacement involves one element being replaced by another in a compound, which is not the case here.
  • Decomposition involves a single compound breaking down into two or more simpler substances, which is not applicable here.
  • Exchange (also known as double replacement or double displacement) involves the exchange of ions between two compounds to form two new compounds, which matches the given reaction.
  • Combination involves two or more substances combining to form a single compound, which is not applicable here.

Final Answer

The correct type of reaction is an exchange reaction. Therefore, the answer is:

\[ \boxed{\text{Exchange}} \]
