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 .
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 ...
Morocco has about 22 billion cubic meters of conventional renewable water resources per year equivalent to 730 cubic meter/capita/year. Before taking into account drought years of the 1990s and 2000s total renewable water resources were estimated to be much higher at around 29 billion cubic meters [2] [3] However, only up to 20 billion cubic meter per year can be economically captured ...
Note: ρ is density, n is refractive index at 589 nm, [clarification needed] and η is viscosity, all at 20 °C; T eq is the equilibrium temperature between two phases: ice/liquid solution for T eq < 0–0.1 °C and NaCl/liquid solution for T eq above 0.1 °C.
The process has a high energy consumption, for example around 2,500 kWh (9,000 MJ) of electricity per tonne of sodium hydroxide produced. Because the process yields equivalent amounts of chlorine and sodium hydroxide (two moles of sodium hydroxide per mole of chlorine), it is necessary to find a use for these products in the same proportion.
Energy consumption per unit weight of product is not far below that for iron and steel manufacture [14] and greater than for the production of glass [15] or cement. [ 16 ] Since electricity is an indispensable raw material for the production of chlorine, the energy consumption corresponding to the electrochemical reaction cannot be reduced.
The company operates a 540 kwh storage facility for solar cells on the roof of a shopping center, and produces over a million battery units per year from sustainable, non-toxic materials. [ 11 ] The key to the ZEBRA design was the development of a mixture of nickel and BASE-like sodium aluminum chloride to produce a new solid electrolyte.
