Water covers about 71% of the Earth's surface, with seas and oceans making up most of the water volume (about 96.5%). [22] Small portions of water occur as groundwater (1.7%), in the glaciers and the ice caps of Antarctica and Greenland (1.7%), and in the air as vapor, clouds (consisting of ice and liquid water suspended in air), and precipitation (0.001%). [23] [24] Water moves continually ...

Sodium carbonate is obtained as three hydratesand as the anhydrous salt: 1. sodium carbonate decahydrate (natron), Na2CO3·10H2O, which readily efflorescesto form the monohydrate. 2. sodium carbonate heptahydrate (not known in mineral form), Na2CO3·7H2O. 3. sodium carbonate monohydrate (thermonatrite), Na2CO3·H2O. Also known as crystal carbonate. 4....
Some common applications of sodium carbonate include: 1. As a cleansing agent for domestic purposes like washing clothes. Sodium carbonate is a component of many dry soap powders. It has detergent properties through the process of saponification, which converts fats and grease to water-soluble salts(specifically, soaps). 2. It is used for lowering ...
The integral enthalpy of solution of sodium carbonate is −28.1 kJ/mol for a 10% w/w aqueous solution. The Mohs hardnessof sodium carbonate monohydrate is 1.3.
Sodium carbonate is soluble in water, and can occur naturally in arid regions, especially in mineral deposits (evaporites) formed when seasonal lakes evaporate. Deposits of the mineral natron have been mined from dry lake bottoms in Egypt since ancient times, when natron was used in the preparation of mummiesand in the early manufacture of glass. T...
The initial large-scale chemical procedure was established in England in 1823 to manufacture soda ash.

Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H2, sometimes called dihydrogen, [11] but more commonly called hydrogen gas, molecular hydrogen or simply hydrogen. It is colorless, odorless, tasteless, [12] non-toxic, and highly combustible. Constituting approximately 75 ...
Archimedes died during the siege of Syracuse, when he was killed by a Roman soldier despite orders that he should not be harmed. Cicero describes visiting Archimedes' tomb, which was surmounted by a sphere and a cylinder that Archimedes requested be placed there to represent his mathematical discoveries.
The IP code or ingress protection code indicates how well a device is protected against water and dust. It is defined by the International Electrotechnical Commission (IEC) under the international standard IEC 60529 [1] which classifies and provides a guideline to the degree of protection provided by mechanical casings and electrical enclosures ...
