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 ...

Carbon dioxide reacts with water to produce carbonic acid. The double arrow means that carbonic acid breaks down pretty readily to form carbon dioxide and water again. A hydrogen atom from the ...

The concept of carbon capture, removal and storage is fairly simple, but in practice it’s much more complicated and controversial.

The reactants are on the left side of the equation and the products are on the right. In the reaction, the bonds in the methane and oxygen molecule come apart, the atoms rearrange and then re-bond to ...

During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by ...
