Compounds have fixed composition by mass. E.g., in a single molecule of water, there are two Hydrogen atoms and one oxygen atom; if we add one more oxygen atom, it becomes hydrogen peroxide.The mixture has no fixed composition by mass. E.g., add sugar into water, we get a mixture....
Combustion mixtures—hydrocarbon–air mixtures involve complex sets of chemical reactions between C, O, H and N atoms and their compounds. Such models rapidly evolve into very large databases of species with a tremendous number of reactions. For example, methanol oxidation has been treated with a ...
The inventive mixture of at least one colophonium resin and/or its derivatives and at least one wax is characterised in that the wax is solid at 15, especially 20 DEG C. The waxes used are preferably wax-type fatty substances based on fatty acids with more than 6 C-atoms. The mixtures...
