The oceans are regarded as carbon dioxide sinks, not sources. This means they remove carbon dioxide, not produce it. Carbon dioxide dissolves from the air into ocean water. Once there it is removed by plankton and algae, by corals and mollusks in making shells, and by chemical action.

C + O2 -------> CO2 12g of carbon produces 44g of carbon dioxide 1kg of carbon will produce 3-67kg of carbon dioxide
This depends on the chemical composition of the hydrocarbon.
Plants and trees remove carbon dioxide from the atmosphere through photosynthesis. The ocean also absorbs carbon dioxide, so much now that it is becoming more acidic.
Only that required to build the dam and make its component machinery. Hydroelectric power (produced by the operation of the dam) does not produce any new carbon dioxide.
The ocean water absorbed much of the carbon dioxide from the atmosphere.

From 16 g methane and 64 g oxygen are obtained 44 g carbon dioxide.
can be used for photosynthesis
Sprite has 6% of carbon dioxide
None. Light bulbs do not emit carbon dioxide. The electricity used to power the light bulb may have been produced by a method which emits carbon dioxide (then again, it may not have), but the bulb itself doesn't emit anything except heat and light.
Carbon dioxide absorption by the oceanis affected by how much is there already and solubility equilibrium.The second first - carbon dioxide dissolves into sea water depending on temperature. Warmer water can hold less. As a consequence sunlight can reduce the absorptive capacity by warming the water.Carbon dioxide enters the water to bring up the carbon dioxide levels to saturation levels. If the level in the water is educed by being absorbed by plants (algae) there is a deficiency of carbon dioxide and more carbon dioxide enters the water to make up the deficiency. Algae is more active when exposed to sunlight and absorbs more carbon dioxide. Sunlight thus enhances that amount of carbon dioxide transferring to the water from the atmosphere.
