Succinosuccinic ester behaves both as a ketone and as a phenol, thereby exhibiting desmotropy; assuming the ketone formula as indicating the constitution, then in Baeyer's equation we have a migration of a hydrogen atom, whereas to bring Ladenburg's formula into line, an oxygen atom must migrate.
According to Armstrong, anthracene behaves unsymmetrically towards substituents, and hence one lateral ring differs from the other; he represents the molecule as consisting of one centric ring, the remaining medial and lateral ring being ethenoid.
By actual observations it has been shown that ether, alcohol, many esters of the normal alcohols and fatty acids, benzene, and its halogen substitution products, have critical constants agreeing with this originally empirical law, due to Sydney Young and Thomas; acetic acid behaves abnormally, pointing to associated molecules at the critical point.
By this method it is shown that water, when present as " water of crystallization," behaves as if it were ice.
The nitro group behaves very similarly to the hydroxyl group. The effect of varying the position of the nitro group in the molecule is well marked, and conclusions may be drawn as to the orientation of the groups from a knowledge of the crystal form; a change in the symmetry of the chemical molecule being often attended by a loss in the symmetry of the crystal.
It behaves as a powerful reducing agent, and on hydrolysis with dilute mineral acids is decomposed into formaldehyde and hydroxylamine, together with some formic acid and ammonia, the amount of each product formed varying with temperature, time of reaction, amount of water present, &c. This latter reaction is probably due to some of the oxime existing in the form of the isomeric formamide HCO NH 2.
It is very explosive, dissolves readily in water and behaves as a dibasic acid.
Roughly speaking, therefore, cobalt behaves oppositely to iron.
The truth appears to be that a hardened steel rod generally behaves like one of iron or soft steel in first undergoing extension under increasing magnetizing force, and recovering its original length when the force has reached a certain critical value, beyond which there is contraction.
The influence of high temperature on cobalt was very remarkable, completely altering the character of the change of length: the curves for annealed cobalt show that at 45 this metal behaves just like iron at ordinary temperatures, lengthening in fields up to about 300 and contracting in stronger ones.
Steel behaves in a similar manner, but the maximum permeability is not so high as in iron, and the fall, when the critical point is approached, is less abrupt.
The symbol e 0 behaves exactly like i in ordinary algebra; Hamilton writes I, i, j, k instead of eo, el, e2, es, and in this notation all the special rules of operation may he summed up by the equalities = - I.
The solution when subjected to distillation behaves very much like a physical solution of the oxide in hydrochloric acid, while a solution of orthostannic acid in hydrochloric acid behaves like a solution of SnC1 4 in water, i.e.
In opposition to stannous chloride, even sulphurous acid (solution) behaves as an oxidizing agent.
It behaves as a strong acid and on treatment with phosphorus pentachloride at high temperatures gives triazole.
Glass containing gold behaves in almost precisely the same way, but the ruby glass is less crimson than copper ruby glass.
It behaves as a reducing agent.
Silicon, so far as we know, behaves to metals pretty much like carbon, but our knowledge of facts is limited.
To acids and to alkalis it behaves like the oxide, but dissolves more readily.
It is a white solid, which readily decomposes water in the cold and behaves as a strong reducing agent.
The ordinary hydrated variety forms quadratic crystals and behaves as a strong base.
The blood of most species behaves differentially towards precipitants, and it is therefore conceivable that when blood is used as food and is elaborated into special compounds for the nutrition of the reproductive organs of a parasite, these specific or larger differences in the blood of animal hosts may prevent the ripening of the gonads of a widely diffused parasite and only one particular kind of blood prove suitable.
The thinnest possible spherical shell of metal, such as a sphere of insulator coated with gold-leaf, behaves as a conductor for static charge just as if it were a sphere of solid metal.
It is a colourless solid and behaves as a dibasic acid.
Then rahd); at the end of every word it behaves like ts, that is to say, changes.into u (preu, p, r e t i u m); instead of ts the second person plural of the verba t(i)s, e t(i)s, it(i)snow has au, eu, ia after having had ats, els its..
In some reactions it behaves as having the first formula, in others as having the second.
At angles other than the polarizing angle common light gives a reflected stream .that behaves as a mixture of common light with light polarized in the plane of incidence, and is accordingly said to be partially polarized in that plane.
Or 4° C. Above this point water continuously expands, and at no temperature is it less dense than ice as is shown by the following table: - Density of ice at o°C. = 9175 „ water at o°C. = 99988 4°C. = 1.00000 Io °C. _ 99976 Ioo°C. _ 95866 Under the influence of heat, ice itself behaves as most solids do, contracting when cooled, expanding when heated.
Alcohols may be readily prepared from the corresponding alkyl haloid by the action of moist silver oxide (which behaves as silver hydroxide); by the saponification of their esters; or b the reduction of of h dric alcohols by P Y Y with hydriodic acid, and the subsequent conversion of the resulting alkyl iodide into the alcohol by moist silver oxide.
