Methane Combustion Products Explained

Complete combustion of methane ($CH_4$) occurs when it reacts with a sufficient supply of oxygen ($O_2$). This reaction involves the complete breakdown of the methane molecule.

The balanced chemical equation for this reaction is:

$CH_4(g) + 2O_2(g) \rightarrow CO_2(g) + 2H_2O(g)$

Based on the balanced equation, the products formed from the complete combustion of methane are:

• Carbon dioxide ($CO_2$)
• Water ($H_2O$)

Conditions that limit oxygen supply would lead to incomplete combustion, potentially forming carbon monoxide ($CO$) or solid carbon ($C$). However, under the condition of sufficient oxygen, only carbon dioxide and water are produced.
