"I hope it will. That's what I intend to find out." "How does it work?" Phyl asked, fascinated. Tom explained, "Actually its function is to replace the carbon dioxide that I exhale with fresh oxygen drawn from the water. Otherwise, although the carbon dioxide I'd breathe out would be a very small amount at a time, it soon would make the air unfit.
"Well, I have the airship, and I can see my way clear to perfecting a device to drop the chemicals in metal tanks or bombs," went on Tom. "But what bothers me is the chemical mixture that will put out fires better than the carbon dioxide mixtures now on the market." "I haven't given that much study myself," said Mr. Baxter. "But you are welcome to anything I have, Mr. Swift.
He would be more astounded to learn that beneath the appearances, the changes, so alarming him, there are profound alterations in the rate at which he is taking in oxygen, burning up sugar, accumulating carbon dioxide and excreting waste byproducts through the kidneys, which are responsible for them. The differences between the normal and abnormal are only a matter of degree.
It is a triumph for Mr. And what now? Delegates, credential holders, audience, and the Reverend Mr. Crane draw long breaths of heated carbon dioxide. Postmaster Burrows of Edmundton, in rounded periods, is putting in nomination his distinguished neighbour and fellow-citizen, the Honourable Adam B. Hunt, who can subscribe and say amen to every plank in that platform.
At the Ontario Station, the average amounts of carbon dioxide under a large number of hens was .32 of one per cent., or about ten times that of fresh air, or one-sixth of that which the man breathed so happily in the respiratory calorimeter. With incubators, every conceivable scheme was tried to change the amount of carbon dioxide.
In combustion, the oxygen combines rapidly with the carbon, giving out heat and light and carbon dioxide, but why it does so admits of no explanation. Herein again is where life differs from fire; we can describe combustion in terms of chemistry, but after we have described life in the same terms something and this something is the main thing remains untouched.
And we can regulate its final temperature by how fast we pipe it through just keep it moving enough to reach the level where carbon dioxide freezes out, but the oxygen stays a gas. Then pass it around the engines we'll have to cut out the normal cooling set-up, but that's okay warm it up.... Sure, I've got equipment enough for that. We can set it up in a day.
Weight of sample 1.000 gram; volume of 0.25 N hydrochloric acid required for phenolphthalein end-point, 26.40 cc.; after adding an excess of acid and boiling out the carbon dioxide, the total volume of 0.25 N hydrochloric acid required for phenolphthalein end-point, 67.10 cc. !Answer!: 69.95% Na CO ; 30.02% NaHCO .
Frozen carbon dioxide, it has been suggested; but this is hardly satisfactory, for it offers no explanation of the fact that when the polar caps diminish, and in proportion as they diminish, the "seas" and the canals darken and expand, whereas a reasonable explanation of the correlation of these phenomena is offered if we accept the view that the polar caps consist of snow.
Arcot stopped the ship and held it motionless at ten miles while Wade made his chemical analysis of the air. The report looked favorable; plenty of oxygen and a trace of carbon dioxide mixed with nitrogen. "But the water vapor!" Wade said. "The air is saturated with it! It won't be the heat, but the humidity that'll bother us to coin a phrase."
