However, this yields only very small quantities of CO2. For example, the reaction between. HCl + Ca. CO3 . Such reactions are accompanied by foaming or bubbling. In industry such reactions are widespread because they can be used to. As. an example the chemical reaction between methane and oxygen is given below. CH4 + 2 O2 . The large number of reactions involved are exceedingly complex and not. Refer to (cellular respiration. The relative concentrations of CO2, H2. CO3. and the deprotonated forms HCO3.

Atmospheric concentrations of carbon dioxide fluctuate slightly. Northern Hemisphere. Concentrations of. Concentrations also vary considerably on a. See. greenhouse effect for more. This is an. output rate of 0. Wh. Carbon. dioxide is also produced by hot springs such as those at the Bossoleto site near. Rapolano Terme in Tuscany, Italy. Here, in a bowl- shaped depression of about 1. CO2 rise to above 7. The oceans. act as an enormous carbon sink, having . Accordingly. the ability of the oceans to absorb carbon dioxide from the atmosphere decreases. Some is. consumed in photosynthesis by organisms in the water, and a small proportion of. There is considerable concern that as a. CO2 in the atmosphere the acidity of seawater has. In. particular, with increasing acidity, the availability of carbonates for forming. This includes all. In higher animals, the carbon. In plants using photosynthesis, carbon dioxide is absorbed from the. Free oxygen is released as gas from the. This energy is. required for the fixation of carbon dioxide in the. Calvin. cycle to form sugars. These sugars can then be used for growth within the. Plants can potentially grow up to 5. CO2 when compared with ambient. For example a growing forest will absorb. CO2 each year, however a mature forest will produce as. CO2 from respiration and decomposition of dead specimens (e. Additionally, and. CO2. in the upper ocean and thereby promotes the absorption of CO2 from. At. concentrations of three per cent by volume in air, it is mildly narcotic and. At. concentrations of about five per cent by volume it causes stimulation of the. At about eight per cent concentration it. During the Lake Nyos tragedy of 1. For short- term (under ten. U. S.
