Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone (>C=O).It is a colorless, highly volatile, and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops.
Calcium and bicarbonate ions are largely deposited into the ocean from the weathering of rock formations and are transported via riverine input. This process occurs on very long timescales. [44] Weathering accounts for approximately 60-90% of solute calcium within the global calcium cycle. [49]
Marine chemistry, also known as ocean chemistry or chemical oceanography, is the study of the chemical composition and processes of the world’s oceans, including the interactions between seawater, the atmosphere, the seafloor, and marine organisms. [2]

Sedimentation is a long-term sink for carbon in the ocean, as well as the largest loss of carbon from the oceanic system. [43] Deep marine sediments and geologic formations are important since they provide a thorough record of life on Earth and an important source of fossil fuel. [ 43 ]
Deuterated acetone is prepared by the reaction of acetone with heavy water, 2 H 2 O or D 2 O, in the presence of a base. In this case, the base used is deuterated lithium hydroxide : [ 1 ] In order to fully deuterate the acetone, the process is repeated several times, distilling off the acetone from the heavy water, and re-running the reaction ...
