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 ...

When soda companies add carbon dioxide gas to a soda mixture, the water is very cold so it can hold a lot of gas. They also use pressure to put more gas in the water than it could normally hold at ...

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 ...
