Question

CH4 (g) + O2 (g) → H2O (l) + CO2 (g)

This is an example of:

A. Synthesis

B. Combustion

C. Double replacement

D. Decomposition

Answer 1

B. Combustion.

Step-by-step explanation:

Looking at the given equation, we can see that methane (CH4) reacts with oxygen (O2) and releases water (H2O) and carbon dioxide (CO2). This matches the definition of a combustion reaction. Therefore, the answer is B. Combustion.
