Question

theres an additional guideline for recognizing redox reactions. when something changes from its elemental form to being part of a compound, as with oxygen in the reaction below, the reaction is considered to be a redox reaction.
do you remember which of the five types the following redox reaction is?
redox
$ch_4(g)+2o_2(g)\to co_2(g)+2h_2o(g)$

Explanation:

Combustion reactions involve a substance reacting with oxygen, usually producing carbon dioxide and water. In the given reaction \(CH_4(g)+2O_2(g)\to CO_2(g)+2H_2O(g)\), methane (\(CH_4\)) reacts with oxygen (\(O_2\)) to form carbon dioxide (\(CO_2\)) and water (\(H_2O\)), which is characteristic of a combustion reaction.

Answer:

Combustion
