Question

16/50
what reaction has the following general formula:
ab --> a + b
combustion single replacement combination decomposition double replacement

Explanation:

To determine the reaction type, we analyze the general formula \( AB
ightarrow A + B \). A decomposition reaction is defined as a reaction where a single compound (AB) breaks down into two or more simpler substances (A and B). Combustion involves reacting with oxygen, single replacement is \( A + BC
ightarrow AC + B \), combination is \( A + B
ightarrow AB \), and double replacement is \( AB + CD
ightarrow AD + CB \). So the formula matches decomposition.

Answer:

Decomposition (the option labeled "Decomposition")
