However, this electrolysis process is currently more expensive than creating hydrogen from methane without CCS and the efficiency of energy conversion is inherently low. [130] Hydrogen can be produced when there is a surplus of variable renewable electricity , then stored and used to generate heat or to re-generate electricity. [ 136 ]
The Trinity UFO case is a crashed spaceship story-conspiracy theory set in August 1945 near the Trinity test, where the first atomic bomb had been detonated five weeks prior.
The standard enthalpy change of combustion, ΔH° c, expressed per mole of ammonia and with condensation of the water formed, is −382.81 kJ/mol. Dinitrogen is the thermodynamic product of combustion: all nitrogen oxides are unstable with respect to N 2 and O 2, which is the principle behind the catalytic converter.
Water is an inorganic compound with the chemical formula H 2 O.It is a transparent, tasteless, odorless, [c] and nearly colorless chemical substance.It is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent [20]).
Kepler-37b is an exoplanet orbiting the star Kepler-37 in the constellation Lyra. [3] As of February 2013, it is the smallest planet discovered around a main-sequence star, with a radius slightly greater than that of the Moon and slightly smaller than that of Mercury. [4]
It's generally assumed that Mannlicher derived his 6.5 mm cartridge from an experimental 6.5 mm rimmed Luigi Scotti design, a precursor of the 6.5×52mm Carcano, which was provided to him by the Italian government in 1890 in order to build a rifle for it.
