Inorganic chemistryInorganic chemistry deals with synthesis and behavior of inorganic and organometallic compounds. This field covers chemical compounds that are not carbon-based, which are the subjects of organic chemistry. The distinction between the two disciplines is far from absolute, as there is much overlap in the subdiscipline of organometallic chemistry. It has applications in every aspect of the chemical industry, including catalysis, materials science, pigments, surfactants, coatings, medications, fuels, and agriculture.
Sulfur trioxideSulfur trioxide (alternative spelling sulphur trioxide, also known as nisso sulfan) is the chemical compound with the formula SO3. It has been described as "unquestionably the most important economically" sulfur oxide. It is prepared on an industrial scale as a precursor to sulfuric acid. Sulfur trioxide exists in several forms - gaseous monomer, crystalline trimer, and solid polymer. Sulfur trioxide is a solid at just below room temperature with a relatively narrow liquid range. Gaseous SO3 is the primary precursor to acid rain.
Acid rainAcid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average. The more acidic the acid rain is, the lower its pH is. Acid rain can have harmful effects on plants, aquatic animals, and infrastructure.
National Oceanic and Atmospheric AdministrationThe National Oceanic and Atmospheric Administration (abbreviated as NOAA ˈnoʊ.ə ) is a Washington, D.C.–based scientific and regulatory agency within the United States Department of Commerce, a United States federal government department. The agency is charged with forecasting weather, monitoring oceanic and atmospheric conditions, charting the seas, conducting deep sea exploration, and managing fishing and protection of marine mammals and endangered species in the U.S. exclusive economic zone.
Atmospheric electricityAtmospheric electricity describes the electrical charges in the Earth's atmosphere (or that of another planet). The movement of charge between the Earth's surface, the atmosphere, and the ionosphere is known as the global atmospheric electrical circuit. Atmospheric electricity is an interdisciplinary topic with a long history, involving concepts from electrostatics, atmospheric physics, meteorology and Earth science. Thunderstorms act as a giant battery in the atmosphere, charging up the electrosphere to about 400,000 volts with respect to the surface.
Bashar al-AssadBashar al-Assad (born 11 September 1965) is a Syrian politician who is the current and 19th president of Syria since 17 July 2000. In addition, he is the commander-in-chief of the Syrian Armed Forces and the secretary-general of the Central Command of the Arab Socialist Ba'ath Party, which nominally espouses a neo-Ba'athist ideology. His father and predecessor was General Hafez al-Assad, whose presidency between 1971 and 2000 marked the transfiguration of Syria from a republican state into a dynastic dictatorship tightly controlled by an Alawite-dominated elite composed of the armed forces and the Mukhabarat (secret services), who are loyal to the al-Assad family.
Robert MugabeRobert Gabriel Mugabe (mʊˈɡɑːbi; muɡaɓe; 21 February 1924 – 6 September 2019) was a Zimbabwean revolutionary and politician who served as Prime Minister of Zimbabwe from 1980 to 1987 and then as President from 1987 to 2017. He served as Leader of the Zimbabwe African National Union (ZANU) from 1975 to 1980 and led its successor political party, the ZANU – Patriotic Front (ZANU–PF), from 1980 to 2017. Ideologically an African nationalist, during the 1970s and 1980s he identified as a Marxist–Leninist, and as a socialist after the 1990s.
ChloromethaneChloromethane, also called methyl chloride, Refrigerant-40, R-40 or HCC 40, is an organic compound with the chemical formula . One of the haloalkanes, it is a colorless, sweet-smelling, flammable gas. Methyl chloride is a crucial reagent in industrial chemistry, although it is rarely present in consumer products, and was formerly utilized as a refrigerant. Chloromethane is an abundant organohalogen, anthropogenic or natural, in the atmosphere. Laboratory cultures of marine phytoplankton (Phaeodactylum tricornutum, Phaeocystis sp.
Dominant-party systemA dominant-party system, or one-party dominant system, is a political occurrence in which a single political party continuously dominates election results over running opposition groups or parties. Any ruling party staying in power for more than one consecutive term may be considered a dominant party (also referred to as a predominant or hegemonic party). Some dominant parties were called the natural governing party, given their length of time in power.
