Final answer:
The chemical formula for carbon dioxide is CO₂ and for methane is CH₄. The combination of 3 molecules of carbon dioxide and one molecule of methane is represented by the equation 3CO₂ + CH₄.
Step-by-step explanation:
The chemical formula for carbon dioxide is CO₂. This means that one molecule of carbon dioxide consists of one carbon atom and two oxygen atoms, represented by the symbol CO₂. The chemical formula for methane is CH₄, which means that one molecule of methane contains one carbon atom and four hydrogen atoms, represented by the symbol CH₄.
When we combine the two molecules, 3 molecules of carbon dioxide (3CO₂) and one molecule of methane (CH₄), we can represent it as 3CO₂ + CH₄.
