Calcium carbonate equilibrium pressure must exceed total atmospheric pressure of 101 kPa, which happens at 898 °C. Calcium carbonate is poorly soluble in pure water (47 mg/L at normal atmospheric CO partial pressure as shown below). The equilibrium of its solution is given by the equation (with dissolved calcium carbonate on the right): where the solubility product for [Ca] [CO] is given as anywhere from "K" = 3.7×10 to "K" = 8.7×10 at 25 °C, depending upon the data source. What the equation means is that the product of molar concentration of calcium ions (moles of dissolved Ca per liter of solution)
Society for Scientific Exploration X-Files or in the National Enquirer shows up first here. But what also shows up is a surprising attitude of skepticism." The society's magazine, the "Journal of Scientific Exploration", was established to provide a scientific forum for ufology, parapsychology and cryptozoology, having published research articles, essays, book reviews and letters on those and many other topics that are largely ignored in mainstream journals. The journal is currently edited by parapsychologist and philosopher Stephen E. Braude. The Spirituality and Psychiatry Special Interest Group of the Royal College of Psychiatrists says that the journal has reports about anomalies in science, particularly in
