In chemistry, a reactivity series (or reactivity series of elements) is an empirical, calculated, and structurally analytical progression [1] of a series of metals, arranged by their "reactivity" from highest to lowest.
Triple Award Science, commonly referred to as Triple Science, results in three separate GCSEs in Biology, Chemistry and Physics and provide the broadest coverage of the main three science subjects. The qualifications are offered by the five main awarding bodies in England; AQA , Edexcel , OCR , CIE and Eduqas .
Description: This book explained Dalton's theory of atoms and its applications to chemistry. Importance: The book was one of the first to describe a modern atomic theory, a theory that lies at the basis of modern chemistry. [3]: 251 It is the first to introduce a table of atomic and molecular weights.
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.
For GCSE Science the old single-award ‘science’ and ‘additional science’ options are no longer available, being replaced with a double award ‘combined science’ option (graded on the scale 9–9 to 1–1 and equivalent to 2 GCSEs). Alternatively pupils can take separate qualifications in chemistry, biology and physics.
N 2 (g) + 3 H 2 (g) ⇌ 2 NH 3 (g) ΔH = −92 kJ mol −1. Because this reaction is exothermic, it produces heat: N 2 (g) + 3 H 2 (g) ⇌ 2 NH 3 (g) + heat. If the temperature were increased, the heat content of the system would increase, so the system would consume some of that heat by shifting the equilibrium to the left, thereby producing ...
Nomenclature of Inorganic Chemistry, by chemists commonly referred to as the Red Book, is a collection of recommendations on inorganic chemical nomenclature. It is published at irregular intervals by the International Union of Pure and Applied Chemistry (IUPAC). The last full edition was published in 2005, [8] in both paper and electronic versions.
