The storing of energy by chemical means may be illustrated by decomposing potassium chlorate with heat or by decomposing water by means of a current of electricity. Study the transfer of energy from the body to surrounding objects, as in moving substances and lifting weights. Fill a half gallon jar two thirds full of water and carefully take the temperature with a chemical thermometer.
Pa seems to want to encourage me, and is willing to take anything that I ask him to, He had a sore throat and wanted something for it, and the boss drugger told me to put some tannin and chlorate of potash in a mortar, and grind it, and I let Pa pound it with the mortar, and while he was pounding I dropped in a couple of drops of sulphuric acid, and it exploded and blowed Pa's hat clear across the store, and Pa was whiter than a sheet.
It was in the preface to 'Woodstock, and I have been round to borrow the book to read the directions over again, because I was afraid about the 'paste' going off. READ THIS QUICKLY! and tell me, Where is the fulminating paste?" Solomon John was busy winding some covers of paper over a little parcel. It contained chlorate of potash and sulphur mixed. A friend had told him of the composition.
The oxidation of aniline has been carefully investigated. In alkaline solution azobenzene results, while arsenic acid produces the violet-colouring matter violaniline. Hydrochloric acid and potassium chlorate give chloranil. Potassium permanganate in neutral solution oxidizes it to nitrobenzene, in alkaline solution to azobenzene, ammonia and oxalic acid, in acid solution to aniline black.
Thus, during their passage, and for the first year of their settlement on the lunar continent, these adventurous explorers would suffer neither hunger nor thirst. Now about the air in the projectile. There, too, they were secure. Reiset and Regnaut's apparatus, intended for the production of oxygen, was supplied with chlorate of potassium for two months.
Barbicane took enough chlorate of potash and caustic potash for two months, as he feared unforeseen delay. An extremely ingenious machine working automatically put the elements for good air in motion. The projectile, therefore, was ready, and the only thing left to do was to lower it into the gun, an operation full of perils and difficulty.
In late years, owing to the introduction of precautions in their manufacture, the disease has become much less common. The tipping of the match sticks is accomplished by dipping their ends in a warm solution of a composition of phosphorus, chlorate of potassium, with particles of ground flint to assist friction, some coloring agent, and Irish glue.
After a long ebullition in the following solution, we obtain a yellow-brown shade, and then a remarkable fire-red: chlorate of potash, 75 grains; carbonate of nickel, 30 grains; salt of nickel, 75 grains; and water, 10 oz. The following solution gives a beautiful dark-brown colour: chlorate of potash, 75 grains; salt of nickel, 150 grains; and water, 10 oz.
In an air-tight enclosure, then, after a certain time, all the oxygen of the air will be replaced by the carbonic acid a gas fatal to life. There were two things to be done then first, to replace the absorbed oxygen; secondly, to destroy the expired carbonic acid; both easy enough to do, by means of chlorate of potassium and caustic potash.
"One camera. "One light steel cage, large enough for you to stand in. "One five-pound steel tank, with siphon and hose attachment. "One rifle and ammunition. "Three ounces rosium oxyde. "One ounce chlorate strontium. "You will then, within twenty-four hours, set out with the stenographer and the supplies mentioned and join me in camp on Little Sprite Lake.
