In what phase is co2 at 25 atm and −65 °c
Webcarbonic acid, (H2CO3), a compound of the elements hydrogen, carbon, and oxygen. It is formed in small amounts when its anhydride, carbon dioxide (CO2), dissolves in water. CO2 + H2O ⇌ H2CO3 The predominant species are simply loosely hydrated CO2 molecules. Carbonic acid can be considered to be a diprotic acid from which two series of salts can … WebIn CAPER, the carbon from the ethanol produces mostly gaseous CO 2 and some liquid-phase acetate (C 2 H 3 O 2 −). The total ethanol oxidation to CO 2 on the anode competes with the partial oxidation of ethanol to acetate [ 38 , 39 ] as the anode potential increases above −500 mV vs. Ag/AgCl [ 26 ]: (13) C 2 H 5 OH + 5 OH − → C 2 H 3 O 2 − + 4 H 2 O …
