This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
Retail prices vary widely between countries, brands, bottle sizes (0.33 liter to 20 liters) and place of sale (supermarket, fair, restaurant etc.). They range from US$0.05 to US$6 per liter, equivalent to US$50 to US$6,000 per cubic meter .
For comparison, Vienna Standard Mean Ocean Water (the "ordinary water" used for a deuterium standard) contains about 156 deuterium atoms per million hydrogen atoms; that is, 0.0156% of the hydrogen atoms are 2 H. Thus heavy water as defined by the Gold Book includes semiheavy water (hydrogen-deuterium oxide, HDO) and other mixtures of D 2 O, H

In 2013, compounds of sodium and chloride of different stoichiometries have been discovered; five new compounds were predicted (e.g., Na 3 Cl, Na 2 Cl, Na 3 Cl 2, NaCl 3, and NaCl 7). The existence of some of them has been experimentally confirmed at high pressures and other conditions: cubic and orthorhombic NaCl 3 , two-dimensional metallic ...
It was announced in 2008 that the Abu Dhabi–based International Petroleum Investment Company (IPIC) was in the beginning stages of preparations for the construction of an oil refinery at Jorf Lasfar at a cost of $5 billion. With a proposed production capacity of 200, 000 barrels per day (bpd), the refinery is set to be completed in 2013. [9]
What I liked about Storyworth. There’s a lot to like about Storyworth, assuming you either choose to answer the questions yourself or choose to pepper a willing participant.
Normality is defined as the number of gram or mole equivalents of solute present in one liter of solution.The SI unit of normality is equivalents per liter (Eq/L). = where N is normality, m sol is the mass of solute in grams, EW sol is the equivalent weight of solute, and V soln is the volume of the entire solution in liters.
