The purity of the products was ascertained through GC–MS spectroscopy, while the conversion rates were determined utilizing the data obtained from UV–Vis spectroscopy, employing the subsequent equation: Graphite H2SO4, H3PO4 KMnO4 H2O, H2O2 90° C (1) Cu(OAc)2 Toluene Reflux 110°C, 18 ...
Chemical changes are known to occur through chemical reactions. To represent chemical reactions, we use chemical equations. Each chemical equation separates the reactants and products by the use of a reaction arrow →. The chemical equation also contains an equal number of...
These processes can always be written as a pair of half-reaction equations. They are called half-reactions because electrons are present as an actual species and the two equations sum to give a single balanced overall redox reaction equat...
Other fields of study such as stoichiometry depend on having a balanced chemical equation in order to relate amounts of the compounds to each other. There is a special type of reaction that takes additional steps outside the normal way of balancing reactions. These are oxidation-reduction (...
