All types of Chemistry Study Notes For College And Universties
In the vast universe of organic chemistry, we encounter a fascinating phenomenon that challenges our initial intuition about molecular formulas: isomerism. At first glance, we might think that a single molecular formula defines a specific compound with unique properties. However, the reality is much richer and more complex. Two or more compounds can share the … Read more
Chemistry is a science that studies the composition, structure, properties and transformations of matter. In this guide we illustrate the basic notions of chemistry. Chemistry is a rather complex science that deals with the study of the composition, properties, behaviors and ways of reacting of matter. There are various branches that make up this fascinating … Read more
Basic chemistry notions: structure and characteristics of the atom, mole and Avogadro’s number, weight, atomic models and atomic structure. ATOM: STRUCTURE AND CHARACTERISTICS The atom is the smallest part of matter, of which it presents all the physical and chemical characteristics . In terms of composition, the atom is made up of hundreds of subatomic particles of which only 3 present fundamental characteristics … Read more
Binary, Ternary and Acid Salts. What are salts and how are they formed: explanation of the formation and structure of salts. Formulas and examples.What are salts ? Salts are chemical compounds that originate from the reaction of a hydroxide with an acid according to the generic equation: hydroxide + acid → salt + water. BINARY SALTS Binary salts are compounds formed by: metal + … Read more
Glyphosate (N-phosphonomethyl glycine , C 3 H 8 NO 5 P, CAS 1071-83-6) is a broad-spectrum, non-selective herbicide developed for the elimination of weeds and shrubs, especially perennials. It is a total herbicide. It is absorbed by the leaves and not the roots . It can be applied to the leaves, injected into trunks and stems , or sprayed on stumps as a forestry herbicide. The application of glyphosate kills plants because it suppresses … Read more
Benzene. Colorless liquid with a sweet odor. It evaporates quickly into the air and is slightly soluble in water . It is highly flammable and is formed both by natural processes and by human activities. Brief history Benzene was discovered in 1825 by the English scientist Michael Faraday , C6H6, as one of the components of an oil he collected from lighting gas pipes . Its composition … Read more
