aWhen CO2 dissolves into seawater, some of the CO2 reacts with water to form carbonic acid (H2CO3). This makes seawater more acidic, as measured on the pH scale. 当二氧化碳溶化入海水时,某些二氧化碳用水起反应对形式碳酸 (H2CO3)。 这在酸碱度等级使海水酸性,如被测量。[translate]...
b. CO2 goes into the surface water. c. The ocean chemistry is affected. d. CO2decreases the PH and makes the seawater more acidic. e. CO2 levels in the atmosphere go up. [ ] A. a-b-c-d-eB. e-b-c-d-aC. a-e-b-c-dD. e-d-c-b-a 3. Scientist Robert Dore came to ...
"As carbon dioxide dissolves in the water,or seawater in this case,it forms a weak acid(酸),carbonic acid,"Dore explains."And therefore,as the concentration of CO2in the atmosphere goes up and that exchanges with the surface seawater,it drives the pH down,and makes it more acidic." ...
For the CO2-ODHP reaction, an effective catalyst not only needs to selectively activate the C–H bond with suppression of the C–C cleavage, but also has an affinity for CO2activation. As a typical acidic molecule, CO2is preferentially adsorbed on the basic sites of catalysts, while propane...
water. At some time after that it’s likely that the acidic pore water will react with the rock particles that form the reservoir to make variouscarbonate minerals. The descending CO2-laden pore water is good because the CO2that we’ve spent so much time and money injecting is going ...
