Information: - Thermal runaway occurs in situations where an increase in temperature changes the conditions in a way that causes a further increase in temperature, often leading to a destructive result. It is a kind of uncontrolled positive feedback. - Cadet's fuming liquid was the first organometallic compound to be synthesized. In 1760, the French chemist Louis Claude Cadet de Gassicourt (1731-1799) synthesized a red liquid by the reaction of potassium acetate with arsenic trioxide. - Arsenic trioxide is an inorganic compound with the formula . This commercially important oxide of arsenic is the main precursor to other arsenic compounds, including organoarsenic compounds. Approximately 50,000 tonnes are produced annually. Many applications are controversial given the high toxicity of arsenic compounds. - Cacodyl oxide is a chemical compound of the formula [(CH)As]O. This organoarsenic compound is primarily of historical significance since it is sometimes considered to be the first organometallic compound synthesized in relatively pure form. - Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition. - Cacodyl , dicacodyl , tetramethyldiarsine , alkarsine or minor part of the '' Cadet 's fuming liquid '' ( after the French chemist Louis Claude Cadet de Gassicourt ) ( CH3 ) 2As -- As ( CH3 ) 2 is a poisonous oily liquid with a garlicky odor . Cacodyl undergoes spontaneous combustion in dry air . - He obtained a red liquid by the reaction of potassium acetate with arsenic trioxide. This liquid is known as Cadet's fuming liquid and contains the two compounds cacodyl and cacodyl oxide. - Combustion or burning is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. Combustion in a fire produces a flame, and the heat produced can make combustion self-sustaining. Combustion is often a complicated sequence of elementary radical reactions. Solid fuels, such as wood, first undergo endothermic pyrolysis to produce gaseous fuels whose combustion then supplies the heat required to produce more of them. Combustion is often hot enough that light in the form of either glowing or a flame is produced. A simple example can be seen in the combustion of hydrogen and oxygen into water vapor, a reaction commonly used to fuel rocket engines. This reaction releases 242kJ/mol of heat and reduces the enthalpy accordingly (at constant temperature and pressure): - Potassium acetate (KCHCOO) is the potassium salt of acetic acid. After reading the paragraphs above, we are interested in knowing the entity with which 'cacodyl' exhibits the relationship of 'instance of'. Find the answer from the choices below. Choices: - chemical compound - chemical reaction - combustion - enthalpy - formula - hydrogen - inorganic compound - liquid - mixture - oxide - part - salt - sequence - temperature - two

Information: - Charles Thomas Kowal (November 8, 1940 November 28, 2011) was an American astronomer known for his observations and discoveries in the Solar System. As a staff astronomer at Caltech's Mount Wilson and Palomar Mountain observatories between 1961 and 1984, he found the first of a new class of Solar System objects, the centaurs, discovered two moons of the planet Jupiter, and discovered or co-discovered a number of asteroids, comets and supernovae. He was awarded the James Craig Watson Medal for his contributions to astronomy in 1979. - Asteroids are minor planets, especially those of the inner Solar System. The larger ones have also been called planetoids. These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disc of a planet and was not observed to have the characteristics of an active comet. As minor planets in the outer Solar System were discovered and found to have volatile-based surfaces that resemble those of comets, they were often distinguished from asteroids of the asteroid belt. In this article, the term "asteroid" refers to the minor planets of the inner Solar System including those co-orbital with Jupiter. - The Apollo asteroids are a group of near-Earth asteroids named after 1862 Apollo, discovered by German astronomer Karl Reinmuth in the 1930s. They are Earth crossing asteroids that have an orbital semi-major axis greater than that of the Earth (> 1 AU) but perihelion distances less than the Earth's aphelion distance (q < 1.017 AU). - 2063 Bacchus ( / bks / BAK - s ) is an Apollo asteroid and Venus - and Mars - crosser asteroid . It was discovered on April 24 , 1977 , by Charles T. Kowal at the Palomar Observatory . In March 1996 radar observations were conducted at the Goldstone Observatory under the direction of JPL scientists Steven Ostro and Lance Benner , allowing the construction of a model of the object . Optical observations were conducted by Petr Pravec , Marek Wolf , and Lenka Sarounova during March and April 1996 . Bacchus is about 2.6 1.1 1.1 km in size and has a bilobate shape . Its spectral type is Sq. Its name derives from the Roman god Bacchus . On 31 March 1996 , Bacchus passed 0.0677525 AU ( 10,135,630 km ; 6,297,990 mi ) from Earth . After reading the paragraphs above, we are interested in knowing the entity with which '2063 bacchus' exhibits the relationship of 'minor planet group'. Find the answer from the choices below.
