Zeise's salt, potassium trichloro (ethylene)platinate (II) hydrate, is the chemical compound with the formula K [Pt Cl 3 (C 2 H 4)]·H 2 O. The anion of this air-stable, yellow, coordination complex contains an η2 - ethylene ligand. The anion features a platinum atom with a square planar geometry. The salt is of historical importance in the ...
The four most common elements in living organisms – carbon, hydrogen, oxygen, and nitrogen – may be remembered with the acronym CHON. To remember the elements necessary for agriculture; C arbon, H ydrogen, Ca lcium, Iron (Fe), Magnesium (Mg), Manganese (Mn), Copper (Cu), Mo lybdenum, Chlorine (Cl), B oron.
The Central Board of Secondary Education (CBSE) is a national level board of education in India for public and private schools, controlled and managed by the Government of India. Established in 1929 by a resolution of the government, the Board was an experiment towards inter-state integration and cooperation in the sphere of secondary education ...
Lewis structures – also called Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures (LEDs) – are diagrams that show the bonding between atoms of a molecule, as well as the lone pairs of electrons that may exist in the molecule. [1][2][3] A Lewis structure can be drawn for any covalently bonded ...
Salt (chemistry) The crystal structure of sodium chloride, NaCl, a typical salt. The purple spheres represent sodium cations, Na +, and the green spheres represent chloride anions, Cl −. The yellow stipples show the electrostatic forces. In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively ...
The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed. [1][2] The amount of product formed is limited by this reagent, since the reaction cannot continue without it. If one or more other reagents are present in excess of the quantities ...
They are the same as empirical formulae for molecules that only have one atom of a particular type, but otherwise may have larger numbers. An example of the difference is the empirical formula for glucose, which is CH 2 O (ratio 1:2:1), while its molecular formula is C 6 H 12 O 6 (number of atoms 6:12:6). For water, both formulae are H 2 O. A ...
Chemistry is the scientific study of the properties and behavior of matter. [1] It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during reactions with other substances.
