It does not dissociate on heating as do the pentachloride and pentabromide, thus indicating the existence of pentavalent phosphorus in a gaseous compound; dissociation, however, into the trifluoride and free fluorine may be brought about by induction sparks of 150 to 200 mm.
The orthodox were at first cool because they had always dreamed of a nationalism inspired by messianic ideals, while the liberals had long come to dissociate those universalistic ideals from all national limitations.
Let x be the number of molecules which dissociate per second when the number of undissociated molecules in unit volume is unity, then in a dilute solution where the molecules do not interfere with each other, xp is the number when the concentration is p. Recombination can only occur when two ions meet, and since the frequency with which this will happen is, in dilute solution, proportional to the square of the ionic concentration, we shall get for the number of molecules re-formed in one second ye where q is the number of dissociated molecules in one cubic centimetre.
But at length the hopelessness of the Stewart cause and the growth of congregations outside the establishment forced the bishops to dissociate canonical jurisdiction from royal prerogative and to reconstitute for themselves a territorial episcopate.
The oxychloride, bromides, and other compounds were subsequently discovered; here we need only notice Moissan's preparation of the trifluoride and Thorpe's discovery of the pentafluoride, a compound of especial note, for it volatilizes unchanged, giving a vapour of normal density and so demonstrating the stability of a pentavalent phosphorus compound (the pentachloride and pentabromide dissociate into a molecule of the halogen element and phosphorus trichoride).
It was declared in a prefatory note to the volume that the authors were responsible only for their respective articles, but some of these were deemed so destructive that many people banned the whole book, and a noisy demand, led by Samuel Wilberforce, then bishop of Oxford, called on the headmaster of Rugby to dissociate himself from his comrades.
It is impossible also to dissociate pharmacology from clinical therapeutics; the former investigates the agents which are used in the treatment of disease, the latter is concerned with their remedial powers and the conditions under which they are to be used.
As a result of the importance both of the formulae obtained by elementary methods and of those which have involved the previous use of analysis, there is a tendency to dissociate the former, like the latter, from the methods by which they have been obtained, and to regard mensuration as consisting of those mathematical formulae which are concerned with the measurement of geometrical magnitudes (including lengths), or, in a slightly wider sense, as being the art of applying these formulae to specific cases.
Up to the Nicene Council the Church kept Easter coincident with the Jewish Passover, but after that period took elaborate precautions to dissociate the two.
To civil war she was consistently opposed, and never ceased to dissociate herself from the plans of the emigres, but here again her very position made her an enemy of the republic. In any case, all her actions had as their aim - firstly, the safeguarding of the monarchy and the king's position, and later, when she saw this to be impossible, that of securing the safety of her husband and her son.
