The oil and tallows which are chiefly carbon and hydrogen, unite with the oxygen of the air and form carbonic acid and watery vapor, producing heat during the process. So in the capillaries all over the body, the carbon and hydrogen supplied to the blood by the stomach, unite with the oxygen gained in the lungs, and cause the heat which is diffused all over the body.
The molecule has nine parts, of which eight are hydrogen and one oxygen because that is the experimentally known proportion in which oxygen and hydrogen combine to form water. Every substance, however finely divided into molecules, if it is not a simple substance, must therefore have, inside the molecular structure, a further atomic structure.
J.J. Thomson has measured the mass of these positive ions and finds it considerable, i.e. about 150 times that of an atom of hydrogen. Some are even larger, and constitute almost a real grain of dust. We here doubtless meet with the phenomena of disaggregation undergone by metals at a red heat.
"Have her moved," he cried to Aunt Josephine. "Then have a vacuum cleaner go over every inch of wall, carpet and upholstery." Standing beside her, he breathlessly explained his discovery. "That wall paper has been loaded down with arsenic, probably Paris green or Schweinfurth green, which is aceto-arsenite of copper. Every minute you are here, you are breathing arseniuretted hydrogen.
It is water produced from the candle by the action of the air upon its hydrogen. But, besides that, something is going out at the top: it is not moisture it is not water it is not condensible; and yet, after all, it has very singular properties.
Wade, you're a chemist tell us what you think of the explosion of the ship, and of the strange color of our molecular ray in their air." Wade shook his head doubtfully. "I've been trying to figure it out, and I can't quite believe my results. Still, I can't see any other explanation. That reddish glow looked like hydrogen ions in the air.
Its boiling-point, measured with a helium thermometer which has been compared with thermometers of oxygen and hydrogen, is -252°; its critical temperature is -241° C.; its critical pressure, 15 atmospheres. It is four times lighter than water, it does not present any absorption spectrum, and its specific heat is the greatest known. It is not a conductor of electricity.
For the inflation by hydrogen of so small a balloon as his was he made more than ample provision in procuring no less than fifteen casks of 130 gallons capacity each.
The volcanoes we shot three months ago yielded a fine flow of lava with all sorts of metals nickel, beryllium, vanadium, chromium, iridium, as well as copper and iron." "What sort of gas were you speaking about?" she asked. "Hydrogen. That's what's going to make the fireworks; it combines explosively with fluorine.
Here it found some free oxygen floating about, and it seized upon it so violently, that they made a burning flame, while the potassium with its newly found oxygen and hydrogen sank down quietly into the water as potash. And so you see we have got quite a new substance potash in the basin; made with a great deal of fuss by chemical attraction drawing different atoms together.
