H AsO + MgCl + 3NH OH = MgNH AsO + 2NH Cl + 3H O. !Answer!: 30.71 grams. !Answer!: 25.60 cc. If 0.6742 gram of a mixture of pure magnesium carbonate and pure calcium carbonate, when treated with an excess of hydrochloric acid, yields 0.3117 gram of carbon dioxide, calculate the percentage of magnesium oxide and of calcium oxide in the sample. !Answers!: 13.22% MgO; 40.54% CaO. 92.
We hid our treasure by the seashore, and I and my maid watched the battle from the borders of the forest. With the help of Gram, his wondrous sword, and his own great warrior strength, Sigmund was able to harry the great force that came against him. But suddenly he was stricken down. Then was the battle lost.
"I hear your talk about two loads, and it's because I'm on the cart! I won't have it so! You give me that hay! I'll load it; see if I don't!" "Bully for you, Gram!" shouted Halstead. It was no use to try to dissuade her now, as the old Squire well knew from long experience. When her pride was touched no arguments would move her.
And, best of all, two hundred engineers and highly skilled technicians. Quite a few industrial baronies on Gram would realize, before long, what they had lost in those men. He wondered what Lord Trask of Traskon would have thought about that. The Prince of Tanith was no longer interested in what happened to Gram.
The same volume of carbon dioxide at the same temperature and the same pressure is liberated from a 1 gram sample of dolomite, by adding an excess of hydrochloric acid, as can be liberated by the addition of 35 cc. of 0.5 N hydrochloric acid to an excess of any pure or impure carbonate. Calculate the percentage of CO in the dolomite. !Answer!: 38.5%. !Answers!: 0.298 cc.; 0.7300 gram.
By that time, we surely hope, the season will be so far advanced that the weather will have changed for the better. So! You have already estimated the amount of hay in my stack! said Brandur. You have already divided this miserable haycock among yourselves, divided it down to the very last straw. And you have weighed it almost to a gram. Then why speak to me about it?
Determine the percentage of iron in a sample of limonite from the following data: Sample = 0.5000 gram. KMnO used = 50 cc. 1 cc. KMnO = 0.005317 gram Fe. FeSO used = 6 cc. 1 cc. FeSO = 0.009200 gram FeO. !Answer!: 44.60%. If 1 gram of a silicate yields 0.5000 gram of Fe O and Al O and the iron present requires 25 cc. of 0.2 N KMnO , calculate the percentage of FeO and Al O in the sample.
Then stood Regin staring on the earth a long while, and presently thereafter spake from heavy mood: "Mine own brother hast thou slain, and scarce may I be called sackless of the deed." Then Sigurd took his sword Gram and dried it on the earth, and spake to Regin
Halstead, to his credit, had shown that he did not wish grandmother to worry about him. Shortly before two o'clock that afternoon, he had come hastily to the sitting-room door, and said, "Good-by, gram. I'm going away for a spell. Don't worry." Then, shutting the door, he had run off before she could reply or ask a question.
The glass funnels selected for use with paper filters should have an angle as near 60° as possible, and a narrow stem about six inches in length. The filters employed should be washed filters, i.e., those which have been treated with hydrochloric and hydrofluoric acids, and which on incineration leave a very small and definitely known weight of ash, generally about .00003 gram.
