What kind of reaction is symbolized by [tex]A B \rightarrow A + B[/tex]?

A. Double replacement
B. Single replacement
C. Synthesis
D. Decomposition


Sagot :

Let's analyze the given reaction [tex]\( AB \rightarrow A + B \)[/tex].

1. Understanding the Reaction:
- The reaction shows a single compound [tex]\( AB \)[/tex] breaking down into two simpler substances, [tex]\( A \)[/tex] and [tex]\( B \)[/tex].

2. Reaction Types:
- Double Replacement: This reaction involves the exchange of parts between two compounds. An example is [tex]\( AB + CD \rightarrow AD + CB \)[/tex]. This does not match our given reaction.
- Single Replacement: This reaction involves one element replacing another in a compound. An example is [tex]\( A + BC \rightarrow AC + B \)[/tex]. This does not match our given reaction.
- Synthesis: This reaction involves two or more simple substances combining to form a more complex compound. An example is [tex]\( A + B \rightarrow AB \)[/tex]. This does not match our given reaction either.
- Decomposition: This reaction involves a single compound breaking down into two or more simpler substances. An example is [tex]\( AB \rightarrow A + B \)[/tex]. This matches exactly with our given reaction.

3. Conclusion:
- The given reaction [tex]\( AB \rightarrow A + B \)[/tex] is clearly an example of a Decomposition reaction.

So, the correct answer is:
D. Decomposition
