Calculate the grams of calcium oxide and barium oxide in the mixture. !Answers!: 1.824 grams CaO; 0.3877 gram BaO. The reader who desires a more extended discussion of the fundamental theory and its uses is referred to such books as Talbot and Blanchard's !Electrolytic Dissociation Theory! The unit charge is that which is dissociated with a hydrogen ion.
Hydrogen, helium, and calcium are their chief constituents. "Flame-prominences," on the other hand, show, in addition, the characteristic rays of a number of metals, among which iron, titanium, barium, strontium, sodium, and magnesium are conspicuous.
During evaporation a mutual decomposition of the two acids takes place, and the nitric acid is finally decomposed and expelled by the excess of hydrochloric acid. Iron is usually found in the precipitate of barium sulphate when thrown down from hot solutions in the presence of ferric salts.
He took two equal weights of a salt of radium and a salt of barium, which he made oscillate one after the other in a torsion balance. But for this explanation to be admitted, it would evidently need to be supported by very numerous facts.
The solution should not effervesce on addition of nitric or hydrochloric acid. Chlorides. No appreciable precipitate should be produced on addition of silver nitrate solution and nitric acid. Sulphates. No appreciable precipitate should be produced on adding hydrochloric acid and barium chloride.
Barium sulphate, 100 parts; chromic oxide, 20 to 50; finished lacquer, 40 to 50; solvent, 20. This is dried for about 10 minutes at 160° C. Yellow. Barium sulphate, 100 parts; lead chromate, 40; finished lacquer, 40; solvent, 20. This is dried for about 15 minutes at 150° C. Almost all pigments other than the above-mentioned are blackened by contact with lacquer or suspend its drying quality.
He killed him. Jaffery threw a couple of logs on the fire the ship-logs that Adrian loved, and the sea-salts, barium, strontium and what-not, gave green and crimson and lavender flames. "I've seen as much suffering in my time as any man living," he said. "A war-correspondent does. He sees samples of every conceivable sort of hell.
Avenues opened in all directions, lined on both sides with these wonderful houses, which are made of a peculiar stone, veined intermittently with yellow, which has the property of absorbing and emitting light. "It is indeed a phosphori as, if I recall it aright, the sulphides of barium, strontium, and calcium were upon our earth.
Here Varius departs dejected from his weeping friends. Hence we came to Rubi, fatigued: because we made a long journey, and it was rendered still more troublesome by the rains. Next day the weather was better, the road worse, even to the very walls of Barium that abounds in fish. Brundusium ends both my long journey, and my paper. Of true nobility.
It is not isomorphous with the orthorhombic barium and strontium sulphates, as might be expected from the chemical formulae. Distinctly developed crystals are somewhat rare, the mineral usually presenting the form of cleavage masses. The hardness is 3-1/2 and the specific gravity 2.9. The colour is white, sometimes greyish, bluish or reddish.
