Liquid oxygen has a clear cyan color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. [2] Liquid oxygen has a density of 1.141 kg/L (1.141 g/ml), slightly denser than liquid water, and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 1 bar (14.5 psi).
Hydrogen, nitrogen, oxygen and chlorine are cheapest by volume at atmospheric pressure. When there is no public data on the element in its pure form, price of a compound is used, per mass of element contained. This implicitly puts the value of compounds' other constituents, and the cost of extraction of the element, at zero.

[ 46 ] In August 2021, IRC and Water For People launched an alliance and a shared vision called Destination 2030, which aims to reach 200 million people by 2030.
The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).
The Ghana Local Content and Local Participation Bill 2013 is a bill passed in November 2013 by the Ghanaian government that stipulates that Ghanaians should be prioritised in terms of employment in the petroleum industry, and should benefit from the country's resources.
The name liquid nitrogen wash is a little misleading, since no liquid nitrogen is supplied from outside to be used for scrubbing, but gaseous high pressure nitrogen, supplied by the Air separation Unit that usually also provides the oxygen for the upstream Partial Oxidation. [7]
Ghana Water had requested a 400% tariff increase to fully cover costs, but the regulator had pared down the request substantially, citing concerns about affordability. [4] Between 1990 and 1997, the average water tariff in Ghana's urban areas had been in the range of US$0.10 to US$0.15 per m³.
