Question

1. what type of reaction generally occurs when oxygen combines with an organic compound like methane? single - replacement acid - base decomposition combustion

Explanation:

When oxygen reacts with an organic compound like methane, the reaction produces carbon dioxide and water, which is the defining characteristic of a combustion reaction. Single-replacement reactions involve one element replacing another in a compound, acid-base reactions involve acid and base neutralization, and decomposition reactions break a compound into simpler substances, none of which match this scenario.

Answer:

combustion
