Hydrophobicity:After the surface of activated calcium is coated with activator, it has obvious hydrophobic properties. It can be distinguished by the condition of active calcium and inactive calcium dissolved in water. Fluidity: The surface of active calcium is coated with organic active agent molecule...

In the 1920s, Aleksandr Oparin, a Russian biochemist, proposed and developed the idea that life originated in the warm, watery environment of early Earth's surface, under an atmosphere mostly composed of methane.The early seas were believed by Oparin to be rich in simple organic molecules, wh...

Is sodium bicarbonate organic or inorganic? What is the mass of sodium bicarbonate? What is the chemical formula for bicarbonate of soda? Is calcium carbonate a base? What is the pH level of sodium bicarbonate? Is sodium bicarbonate dangerous?
Titration against 1.0 N HCl was used to determine calcium carbonate, as stated by Allen et al. (1976). The amount of oxidizable organic carbon (as an indicator of total organic matter) was calculated using Walkley and Black (1934) rapid titration method as described by Black (1965). A ...

As both the feldspar and carbonate minerals can be dissolved by the acids (e.g., CO2 and organic acids) originating from thermal maturation of organic matter, the potential to generate secondary pores in sandstone reservoirs through the dissolution of the feldspar and carbonate mineral has been ...
In organic chemistry, nitric acid is used fornitration, e.g. by replacing a hydroxyl group. As such it is very important for the synthesis of many commonexplosives, such asnitroglycerin(anddynamite) ortrinitrotoluene (TNT).
