12). Note that because the molar mass of carbon (12) is much smaller than that of iron (56), a small mass proportion (lower scale) in fact corresponds to a large atomic proportion (upper scale) by very roughly a factor of four. For structural matters, we should of course think in ...
(H2CO3). The equilibrium is then established when the carbonic acid is further dissociated into the HCO3−and CO32−. The carbonate anion can react with cations in water (Ca or Mg) in order the precipitation to occur where limestone or dolomite can be formed from this reaction. Carbon ...
The response of carbonate weathering carbon-sink flux (CCSF) to its environmental drivers is still not well understood on the global scale. This hinders understanding of the terrestrial carbon cycle. Here, we show that there is likely to be a widespread and consistent increase in the global CCSF...
After carbonate precipitation with BaCl2 and filtration, the δ13C of evolved CO2 was analysed by an EA-IRMS. We also measured the Δ14C of evolved CO2 by AMS analyses as described above for planted subsoil cores of 0–20 and 40–60 cm depth, and unplanted subsoil cores of 40–60...
and the acetic acid was evaporated under a stream of N2at room temperature. Dimethylformamide, excess potassium carbonate (10 mass equiv.), and excess methyl iodide (10 mass equiv.) were then added to the residue, and the mixture was stirred at room temperature for 3 h. To the slurry,...
On the grounds, the normal volumetric method is considered to specify the total molar quantity adsorbed onto the sample at the studied temperature and pressure, while the mass of the adsorbed phase is obtained using gravimetric assessment after considering the required corrections on the buoyant force...

Other examples concern the electropolymerization of styrene: with lithium perchlorate as electrolyte in propylene carbonate, the formation of perchloric acid at the anodic compartment has been documented.293 With sodium tetrafluoroborate in sulfolane, the true initiator is thought to be boron fluoride (...
