top movie review editor websites for college - DISSCUSION: Carbonates are decomposed by heat into the corresponding oxides and carbon dioxide. The temperature of decomposition depends upon the activity of the metal; that is to say, the more active the metal, the more stable is the carbonate. Only a small portion of the aqueous carbon dioxide exists as carbonic acid. However, in most H 2 CO 3 * (as defined below) is used to represent solution carbonates. * H 2C O 3 =H 2 C 3 + CO 2(aq) (2) Where H 2 CO 3 * is the total dissolved cabon including aqueous carbon dioxide. Carbonic acid dissociates into bicarbonate and carbonate according to the following equations. The carbonate system of the ocean plays a key role in controlling the pressure of carbon dioxide in the atmosphere, which helps to regulate the temperature of the planet. The formation rate of the most prevalent authigenic mineral in the environment, CaCO 3, is also the major sink for dissolved carbon in the long-term global carbon balance. creating a hypothesis
