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 ...

It's also possible, some believe, that the substance could have come about through specific reactions with electrons. "However, we found a distinctly different pathway to produce O2 from molecular CO2 ...

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 ...

HKUST researchers discovered how CO2 reacts in supercritical water, identifying pyrocarbonate ions as key intermediates.
