Carbon dioxide (chemical formula CO2) is an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two ...

Carbon dioxide is present in the atmosphere and contributes to global warming. We write this reaction as a word equation and as the chemical formula, CO₂. This tells us there are two oxygen ...

In the reaction, the bonds in the methane and oxygen molecule come apart, the atoms rearrange and then re-bond to form water and carbon dioxide. The little number written at the lower right after an ...
