Linear equations are so-called, because when they are plotted, they describe a straight line. The simplest equations to solve are linear equations that have only one variable. They contain only constant numbers and a single variable without an exponent. As an example, consider:
An unresolved root, especially one using the radical symbol, is sometimes referred to as a surd [2] or a radical. [3] Any expression containing a radical, whether it is a square root, a cube root, or a higher root, is called a radical expression , and if it contains no transcendental functions or transcendental numbers it is called an algebraic ...
Dimanganese decacarbonyl, [3] which has the chemical formula Mn 2 (CO) 10, is a binary bimetallic carbonyl complex centered around the first row transition metal manganese.The first reported synthesis of Mn 2 (CO) 10 was in 1954 at Linde Air Products Company and was performed by Brimm, Lynch, and Sesny. [4]
For example, is an expression, while the inequality is a formula. To evaluate an expression means to find a numerical value equivalent to the expression. [ 3 ] [ 4 ] Expressions can be evaluated or simplified by replacing operations that appear in them with their result.
Methane is an organic compound, and among the simplest of organic compounds. Methane is also a hydrocarbon. Naturally occurring methane is found both below ground and under the seafloor and is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates.
Thermolysis converts 1 to (E,E) geometric isomer 2, but 3 to (E,Z) isomer 4.. The Woodward–Hoffmann rules (or the pericyclic selection rules) [1] are a set of rules devised by Robert Burns Woodward and Roald Hoffmann to rationalize or predict certain aspects of the stereochemistry and activation energy of pericyclic reactions, an important class of reactions in organic chemistry.
The simplest sulfoxide, dimethyl sulfoxide, is a common solvent; a common sulfone is sulfolane. Sulfonic acids are used in many detergents. Compounds with carbon–sulfur multiple bonds are uncommon, an exception being carbon disulfide , a volatile colorless liquid that is structurally similar to carbon dioxide.
Paul Cézanne, 1888, Mardi gras (Pierot and Harlequin), oil on canvas, 102 cm × 81 cm (40 in × 32 in), Pushkin Museum, Moscow. Several predominant factors mobilized the shift from a more representational art form to one that would become increasingly abstract; one of the most important would be found directly within the works of Paul Cézanne and exemplified in a widely discussed letter ...
