The double decompositions of sodium chloride are almost exclusively based on the possibility of the metal sodium being exchanged for hydrogen and other metals.
Such a representation of salts expresses with great simplicity the capacity of every salt to enter into saline doubledecompositions with other salts; consisting in the mutual replacement of the metals in the salts.
Nitric acid also enters into double decompositions with a number of hydrocarbons not in any way possessing alkaline characters and not reacting with other acids.
In this manner in the manufacture of sodium carbonate the conditions of equilibrium which enter into double decompositions have been made use of (see above), and the aim is to form directly the unchangeable product CaO,2CaS.
The only cases which can be compared with these reactions for simplicity are those exchange decompositions investigated by G.
In a dry state, however, hydrochloric acid does not alter vegetable dyes, and does not effect many double decompositions which easily take place in the presence of water.
And organisms are bodies in which a series of uninterrupted, varied, and active chemical transformations proceed, whilst salts, which only enter into double decompositions between each other, are little prone to such changes.
In double decompositions taking place in dilute solutions where the mass of water is large, its influence, notwithstanding the weakness of affinities, must he great, according to the very essence of Berthollet's doctrine.
The soil was full of organic impurities, including the decompositions of many generations of the dead.
The carbonic acid evolved is principally formed by the decompositions which result from the assimilation of atmospheric oxygen.
But in all the cases the results were the same as before; decompositions of the same kind were effected, and the electric current producing these was in the same direction as in the experiments just described.
Biot does not appear to admit the successivedecompositions and recompositions spoken of by Grotthuss, Davy, &c.
We now proceed to consider the properties, syntheses, decompositions and constitution of the benzene complex.
Formula (4) is symmetrical and based on Kekule's formula: it is in full accord with the syntheses and decompositions of the naphthalene nucleus and the number of isomers found.
Persoz, Professor of Chemistry at Strasburgh, shows the order in which decompositions take place among the successive substances.
This saline compound is to be employed to effect double decompositions with the oxisalts; that is, to convert the radical of another base, combined with an oxacid, into a sulphosalt.
The leaves of plants which absorb both the carbonic acid and the aqueous vapour of the air, answer to the cells in which our decompositions took place.
His final conclusion was, that putrefaction is due to decompositionsof organic matter attendant on the multiplication therein of minute organisms.
Then began that series of combinations and decompositions which now goes on, and which will continue in future.
In consequence of this property, which Bergman considered as the foundation of the whole of the science, the strength of affinity of one body for another is determined by these decompositions and combinations.
In the first, he exhibited the order of decompositions in the moist way, in the second in the dry.
Berthollet admitted that in fact such decompositions often happened; but he accounted for them from other causes, and not from the superior affinity of one body over another.
Such is a very imperfect outline of the electrical theory of affinity first proposed by Davy to account for the decompositions produced by electricity.
Such tables then exhibited to the eye the strength of affinity of all the different bodies that are capable of uniting with one and the same substance, and the order in which decompositions are effected.
The order of decompositionsoften varies with the mode employed.
At such points some of the nerve-colloid will remain in an amorphous state, and as the wave of molecular motion will there be checked, it will tend to cause decompositions amongst the unarranged molecules.
The decompositions must, he says, cause "additional molecular motion to be disengaged; so that along the outgoing lines there will be discharged an augmented wave.
It was with the galvanic current that Davy decomposed the alkalies, and since his day other electro-chemical decompositions have been studied in great number, to the development of important industries.
Electrical decompositions were dualistic in character, but the dualism was not that taught by Berzelius.
Once made, they are dead, and an infinite number of alternative conceptualdecompositions can be used in defining them.
These animalcules are discovered in two or three days in all decompositions of organic matter, whether vegetable or animal, in moderate degrees of warmth with sufficient moisture.
In animal nutrition the organic matter of the bodies of dead animals, or vegetables, is taken into the stomach, and there suffers decompositions and new combinations by a chemical process.
By "stable" we mean they possess considerable resistance to agencies, that, in the case of other salts, effect decompositions of those salts.
Later investigations have somewhat modified and simplified our views of the constitution of the typical lignocellulose (jute), so far as this can be dealt with by the statistics of its more important decompositions (original, pp.
In cases of the separation of the constituents of water, and of solutions of neutral salts forming the whole of the chain, there may possibly be a succession of decompositions and recompositions throughout the fluid.
Is it possible to consider plants and animals as the causes of the destruction of other organisms when their own elements are condemned to undergo the same decompositions as the creatures which have preceded them?
But these chemical decompositions are attended by a corresponding change in the mechanical characters of the soil.
A series of decompositions and recompositions have been supposed to take place, and the communication of effects from particle to particle.
These elections were regarded as constant, and chemists drew up tables for the purpose of showing the order in which these decompositions occur.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "decompositions" in a variety of sentences. We hope that you will now be able to make sentences using this word.
