The lecturer mentioned the escape of quantities of free hydrogen there was some discussion on this point afterwards; that water is broken up is easily understood, but what becomes of the oxygen? Simpson suggests the presence of much oxidizable material. CO2 as a noxious gas also mentioned and discussed causes mythical 'upas' tree sulphurous fumes attend final stages.
His exhaled breath went to a tiny pump that forced it through a hygroscopic filter which at once extracted excess moisture and removed carbon dioxide. The same pump carefully measured a volume of oxygen equal to the removed CO2 and added it to the air it released. The pump made very small sounds indeed, and the valves were almost noiseless, but Joe could hear their clickings.
Science invades everything nowadays, and the officials have recently had the water of one of the sacred wells analyzed by a chemist audacious dog of an infidel and here he comes with his CO2 and all the virtue of this water of life is gone. It is found unfit for human use, and the well is ordered to be closed.
Martin Rogers, and never could I have conceived such an indecorous piece of business, men like them calling one another 'tyro, 'dreamer, and in one place 'block-head. Stanistreet denied that the perfumed odour of almonds attributed to the advancing cloud could be due to anything but the excited fancy of the reporting fugitives, because, said he, it was unknown that either Cn, HCn, or K4FeCn6 had been given out by volcanoes, and the destructiveness to life of the travelling cloud could only be owing to CO and CO2.
The device for which it had waited was simply a preventive of the disaster overtaking the ship from the mine on Orede. It was essentially a tank of liquid oxygen, packed in the space from which stores had been taken away. When the ship's air-supply was pumped past it, first moisture and then CO2 froze out.
Fresh burned lime is only the stone after some worthless matter has been driven off by use of heat. The limestone, carbonate of lime, is represented by the formula CaCO3. When heat is applied under right conditions the carbon dioxide, CO2, is driven off, and there remains CaO, which is calcium oxide, called fresh burned lime.
To flood everything with CO2! But it wasn't CO2! That's what burned!" Major Holt stared sharply at him. He held up his hand. Somebody materialized beside him. He said harshly: "Get the extinguisher bottles sealed and take them to the laboratory." "Yes, sir!" A man went running toward the wreck. Major Holt said coldly: "That's a new one. We should have thought of it.
We know that living tissues give off products, and that these are not merely pure CO2 and H2O, but complicated compounds.
There is no shortage ever of carbon from CO2 in the air and rarely a shortage of hydrogen from water. When the highly digestible starch in manioc is chewed, digestive enzymes readily convert it into sugar. Nutritionally there is virtually no difference between eating manioc and eating white sugar. Both are entirely empty calories.
The snow on top would be frozen CO2; according to the thermocouples, the surface temperature was well below minus-100 Centigrade. No ships on orbit circled it; there was a little faint radiation, which could have been from naturally radioactive minerals; there was no electrical discharge detectable. There was considerable bad language in the command room of the Nemesis.
