The word "Hg" is correct in written English as it represents the chemical symbol for mercury
It is typically used in scientific contexts, particularly in chemistry and physics.
Example: "The thermometer contains Hg, which expands with temperature changes."
Alternatives: "Mercury" or "Element 80."
One day in February, an early-morning drive-by shooting was followed by a series of firebombings, during which dozens of vehicles were set alight outside the traffic-police HG.
Zinc (Zn), cadmium (Cd), and mercury (Hg) also form acetylides, although they are not as well characterized.
A blood pressure greater than 100/60 millimetres of mercury (mm Hg) indicates adequate perfusion.
When S4N4 vapour is pumped through silver wool at 250 300 °C (480 570 °F) and low pressure (less than 1.0 mm Hg), an unstable dimer, S2N2, can be condensed.
Mercury (Hg) has a unique combination of physical properties.
Thus the Egyptian words for "man" and "be bright," both spelled with the same consonants, hg, could be rendered by the same hieroglyph.
In 2009, Agios researchers discovered that the mutated enzyme leaves a different by-product, a molecule called 2-hydroxyglutarate, or 2-HG, which appears to switch off certain genes in the cell nucleus.
A computer readout indicated how much 2-HG, the by-product of the aberrant enzyme, remained in each well.
An Agios team soon devised AG-221, which binds to the abnormal enzyme and prevents it from creating 2-HG.
As the dose of the drug was increased, the amount of 2-HG fell, in some cases as much as ninety per cent.
A minor but still important segment of the explosives industry is the production of detonating agents, or such priming compositions as lead azide [Pb(N3 2], silver azide (AgN3), and mercury fulminate [Hg(ONC 2].
