The Chemistry of Oxygen and Sulfur - Purdue University

The Chemistry of Oxygen and Sulfur. Oxygen is the most abundant element on this planet. The earth's crust is 46.6% oxygen by weight, the oceans are 86% oxygen by weight, and the atmosphere is 21% oxygen by volume. The name oxygen comes from the Greek stems oxys, "acid," and gennan, "to form or generate." Thus, oxygen literally means "acid former."

Methanation process

Methanation is a chemical reaction that converts carbon monoxide and/or carbon dioxide to methane. The production of methane across the "Sabatier" reaction (1) is a well-known process for converting CO 2 to a useful product and was proposed by Paul Sabatier and J.B. Sendersens in 1902. A large-scale production of methane on the basis of carbon dioxide has never been …

Ksp - Chemistry | Socratic

In a saturated solution the solid is in equilibrium with its ions e.g : CaCO3(s) ⇌ Ca2+ (aq) + CO2− 3(aq) The expression for Ksp is: Ksp = [Ca2+ (aq)][CO2− 3(aq)] We don't include the concentration of the solid as this is assumed constant. So if we know the concentration of the ions you can get Ksp at that particular temperature.
