When an acid and an alkali are brought together in the presence of moisture and heat, the result is the rapid production of carbon dioxide, a gas that expands on being heated, just as all other gases do.
In these cases Wöhler adopted the following plan, which resembles that for the indirect determination of carbon dioxide.
It is used as a source of lime and of carbon dioxide.
Carbon dioxide exists in waters in two forms, free and combined.
Note 4: Carbon dioxide is dissolved by cold water, but the gas is expelled by boiling, and, together with that which is distributed through the apparatus, is swept out into the absorption bulb by the current of air.
The remainder of the tube was filled with copper oxide, which served to oxidize any carbon compound, which might be formed by the oxidation of the phosphorus, to carbon dioxide.
Palladium hydrogen was therefore sealed up in a capacious glass tube with a few cubic centimeters of clear lime water and a mixture of carbon monoxide and oxygen free from carbon dioxide.
It remained to test the second of Baumann’s statements; namely that carbon monoxide in the presence of moist phosphorus and air is oxidized to carbon dioxide by the active oxygen formed by the slow combustion of the phosphorus.
Connect the horizontal arm of the entry tube with a cylinder of compressed oxygen (or carbon dioxide, Fig.
In combination with oxygen (as carbon dioxide) it is also found to a small extent in the atmosphere.
These are thrown down from solution either because of cooling, evaporation, the loss of carbon dioxide, or the work of algae.
Digging Peat, Scotland] When vegetation decays in open air the carbon of its tissues, taken from the atmosphere by the leaves, is oxidized and returned to it in its original form of carbon dioxide.
The Chemical Work Of Water As water falls on the earth in rain it has already absorbed from the aircarbon dioxide (carbonic acid gas) and oxygen.
As an example of this, there may be taken the process of lime-burning, which depends on the fact that when calcium carbonate is heated, carbon dioxide is given off and quicklime is produced.
Take, for instance, the dissociation of calcium carbonate into calcium oxide and carbon dioxide.
Maturation involves a cessation, or at least a retardation, of the growth of the embryo, and this is shown to be the result of the accumulation of carbon dioxide in the tissues, which acts as a mild anaesthetic.
During maturation the accumulation of carbon dioxide is due to the seed-coat becoming impermeable to it.
No permanent change takes place in the chlorophyll, but by the action of light it enables the plant to absorb oxygen, carbon dioxide, and water and to use these to build up the complex organic substances which are found in plants.
Carbon dioxide furnishes a white light similar to daylight and small tubes containing this gas are in use to-day where accurate discrimination of color is essential.
Carbon dioxide is a product of combustion, decay, and animal exhalation.
Carbon dioxide will be better known by the older people as carbonic acid.
We have already stated that air is composed of a mixture of oxygen and nitrogen chiefly, with a small amount of carbon dioxide.
Carbon, which we know in an almost pure state in anthracite coal, and in even purer form in diamonds, forms a combination with oxygen known as carbon dioxide.
Carbon dioxide is the gaseous product of the oxidation of carbon and is found in large amounts wherever there is burning, since carbon is the chief constituent of all fuel and whenever carbon is burned, carbon dioxide is formed.
Among the things which are present in the body fluids should be mentioned the two gases oxygen and carbon dioxide.
The lungs get rid especially of carbon dioxide; the skin of water; the renal organs of the products of nitrogenous decay.
The chemist might go on continually manufacturing hydrogen and oxygen, carbon dioxide, ammonia.
Thus the lungs, whilst they get rid principally of carbon dioxide, also get rid of water in the form of steam and of nitrogenous matter.
The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "carbon dioxide" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
