173 examples of carbonate in sentences

Chemists enunciate the result of all the experiments which prove this, by stating that chalk is almost wholly composed of "carbonate of lime.

For carbonate of lime is a widely-spread substance, and is met with under very various conditions.

All sorts of limestones are composed of more or less pure carbonate of lime.

The crust which is often deposited by waters which have drained through limestone rocks, in the form of what are called stalagmites and stalactites, is carbonate of lime.

Or, to take a more familiar example, the fur on the inside of a tea-kettle is carbonate of lime; and, for anything chemistry tells us to the contrary, the chalk might be a kind of gigantic fur upon the bottom of the earth-kettle, which is kept pretty hot below.

If any one were to try to persuade you that an oyster-shell (which is also chiefly composed of carbonate of lime) had crystallized out of sea-water, I suppose you would laugh at the absurdity.

Examined chemically, it proves to be composed almost wholly of carbonate of lime; and if you make a section of it, in the same way as that of the piece of chalk was made, and view it with the microscope, it presents innumerable Globigerinoe embedded in a granular matrix.

Yet this amorphous particle, devoid of everything which, in the higher animals, we call organs, is capable of feeding, growing, and multiplying; of separating from the ocean the small proportion of carbonate of lime which is dissolved in sea-water; and of building up that substance into a skeleton for itself, according to a pattern which can be imitated by no other known agency.

The similarity of the deposit, thus composed of a large percentage of carbonate of lime, and a small percentage of silex, to chalk, regarded merely as a kind of rock, which was first pointed out by Ehrenberg, is now admitted on all hands; nor can it be reasonably doubted, that ordinary metamorphic agencies are competent to convert the "modern chalk" into hard limestone or even into crystalline marble.

The bottom in these two soundings might have been called 'grey ooze,' for although its nature has altered entirely from the Globigerina ooze, the red clay into which it is rapidly passing still contains a considerable admixture of carbonate of lime.

The formation seemed too uniform: wherever we met with it, it had the same character, and it only varied in composition in containing less or more carbonate of lime.

"We conclude, therefore, that the 'red clay' is not an additional substance introduced from without, and occupying certain depressed regions on account of some law regulating its deposition, but that it is produced by the removal, by some means or other, over these areas, of the carbonate of lime, which forms probably about 98 per cent.

We can trace, indeed, every successive stage in the removal of the carbonate of lime in descending the slope of the ridge or plateau where the Globigerina ooze is forming, to the region of the clay.

An ordinary mixture of calcareous Foraminifera with the shells of pteropods, forming a fair sample of Globigerina ooze from near St. Thomas, was carefully washed, and subjected by Mr. Buchanan to the action of weak acid; and he found that there remained after the carbonate of lime had been removed, about 1 per cent.

But Fabroni, full of the then novel conception of acids and bases and double decompositions, propounded the hypothesis that sugar is an oxide with two bases, and the ferment a carbonate with two bases; that the carbon of the ferment unites with the oxygen of the sugar, and gives rise to carbonic acid; while the sugar, uniting with the nitrogen of the ferment, produces a new substance analogous to opium.

THE DOWNS.The well-known substance chalk, which the chemist regards as a nearly pure carbonate of lime, and the microscopist as an aggregation of inconceivably minute shells and corals, forms the sub-soil of the hilly districts of the south-east of England.

(The fever-mixture, we remind our readers, is thus made: Mix a drachm of powdered nitre, 2 drachms of carbonate of potash, 2 teaspoonfuls of antimonial wine, and a tablespoonful of sweet spirits of nitre in half a pint of water.)

But it is formed, as you all know, in the earth, not as a metal, but as a stone, as chalk or limestone, which is a carbonate of lime; that is, calcium combined with oxygen and carbonic-acid gases.

The finest white marble, like that of Carrara in Italy, of which the most delicate statues are carved, is carbonate of lime altered and hardened by volcanic heat.

Then it must be made to set, that is, to return to limestone, to carbonate of lime, by drinking in the carbonic acid from water and air, which some sorts of lime will do instantly, setting at once, and being therefore used as cements.

That is to say, that just as a precipitate of chalk is formed when one throws some carbonate of soda into lime water, so the masculine and the feminine are to be looked upon as precipitates and crystallizations of a long series of linked chemical reactions in the fluids of the body, in which the internal secretions play a determining part.

[Chem], titanium oxide, blanc fixe [Fr.], ceruse^, pearl white; white lead, carbonate of lead.

It combines with lime and potash; and probably the earthy matter of these excavations contains a good proportion of calcareous carbonate.

As the quantity of soda, in the true soda water, is much too small to neutralize the acid, it is a good practice to add fifteen or twenty grains of the carbonate of soda, finely powdered, to each bottle, which may be done by pouring the contents of a bottle on it in a large glass.

Owing to the carbonates that are always present in sewage, ferrous carbonate is also formed.
