Structure and general properties. Hydrogen cyanide is a linear molecule, with a triple bond between carbon and nitrogen. The tautomer of HCN is HNC, hydrogen isocyanide. [citation needed] HCN has a faint bitter almond -like odor that some people are unable to detect owing to a recessive genetic trait. [13] The volatile compound has been used as ...
Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid that is produced on a large scale industrially. It is obtained by acidification of cyanide salts. Organic cyanides are usually called nitriles. In nitriles, the −C≡N group is linked by a single covalent bond to carbon. For example, in acetonitrile ( CH3− ...
Pacemaker current. The pacemaker current ( If, or IKf, also called funny current) is an electric current in the heart that flows through the HCN channel or pacemaker channel. Such channels are important parts of the electrical conduction system of the heart and form a component of the natural pacemaker . First described in the late 1970s in ...
Sodium cyanide is a poisonous compound with the formula Na C N. It is a white, water-soluble solid. Cyanide has a high affinity for metals, which leads to the high toxicity of this salt. Its main application, in gold mining, also exploits its high reactivity toward metals. It is a moderately strong base.
An example of a U.S. classified document; page 13 of a United States National Security Agency report on the USS Liberty incident, partially declassified and released to the public in July 2003. The original overall classification of the page, "Top Secret" code word UMBRA, is shown at top and bottom.
Vice President Kamala Harris on Friday slammed the report by a Justice Department special counsel into Joe Biden's mishandling of classified documents that raised questions about the president's ...
A transcript of special counsel Robert Hur’s two-day interview with President Biden offered a detailed view of the exchanges at the heart of Hur’s report on Biden’s handling of classified ...
Ammonium cyanide is prepared by combining solutions of hydrogen cyanide and ammonia: [citation needed] HCN + NH 3 → NH 4 CN. It may be prepared by the reaction of calcium cyanide and ammonium carbonate: [citation needed] Ca (CN) 2 + (NH 4) 2 CO 3 → 2 NH 4 CN + CaCO 3. In dry state, ammonium cyanide is made by heating a mixture of potassium ...
