I claim: 1. A process for the manufacture of ultra-pure silver nitrate from crude silver that contains metallic contaminants, said process including the steps of: (1) dissolving the crude silver in nitric acid to form a crude silver nitrate solution, (2) diluting the crude silver nitrate solution with water, (3) adding an alkaline agent to the crude silver nitrate solution to precipitate ...

O 2: 3/8 moles were present when the experiment began. All of the O 2 was consumed during the reaction. Thus, 0 g of O 2 remains. CO 2: 3/16 moles were produced by the reaction. This is equivalent to 8.25 g of CO 2. H 2 O: 3/8 moles were produced by the reaction. This is equivalent to 6.75 g of H 2 O.
We have found that Na is the limiting reagent in the reaction, and that for 0.17 moles of Na, 0.17 moles of NaCl are produced. Therefore, the theoretical yield of NaCl in moles is 0.17 moles. But this value is in terms of moles. In the given problem, we need to find out how many grams of NaCl would be produced in the reaction.
(a) In the lab, nitrogen dioxide gas can be prepared by heating copper(II) nitrate. Cu(NO 3 ) 2(s) → CuO (s) + 2NO 2(g) + ½ O 2(g) Calculate the volume of nitrogen dioxide gas produced when 2.0g of copper(II) nitrate is completely decomposed on heating.

  • We have found that Na is the limiting reagent in the reaction, and that for 0.17 moles of Na, 0.17 moles of NaCl are produced. Therefore, the theoretical yield of NaCl in moles is 0.17 moles. But this value is in terms of moles. In the given problem, we need to find out how many grams of NaCl would be produced in the reaction.
  • grams molar mass moles How many moles of silver are produced when 36.92 grams of copper reacts with silver nitrate? ___Cu + ___AgNO3 ( ___Ag + ___Cu(NO3)2. grams molar mass moles Hydrochloric acid (HCl) is reacted with calcium carbonate to produce 7.45 moles of carbon dioxide.
  • If 1.0 mole of copper(II) nitrate decomposes, how many moles of nitrogen dioxide would be formed? a) 0.50 mol b) 4.0 mol c) 1.0 mol d) 2.0 mol e) 6.0 mol A 2.000 g sample of an unknown metal, M, was completely burned in excess O 2 to yield 0.02224 mol of the metal oxide, M2O3.
  • When sufficient silver has been added to precipitate the chloride ion, the next drop of silver nitrate (excess AgNO 3) reacts with the indicator and the color of the solution changes. The analytical chemist can then use the number of milliliters of titrant to determine how many moles of silver ion were added.

How many grams of cryolite are produced if the reaction has a 67.33% yield and a limiting reagent of 35.45 grams of NaOH? 10. (10 pts) Zinc and magnesium metal each react with hydrochloric acid to make the chloride salts of the respective metals, and hydrogen gas. A 10.00 gram mixture of zinc

On Question #6, I had to find the theoretical yield of copper if 2.32 grams of iron was placed into a flask with copper (II) sulfate (CuSO 4). The reaction was Fe+CuSO 4 →FeSO 4 +Cu. I needed to know the molar mass of iron, the mole ratio of moles from the balanced equation, and the molar mass of copper .
13. Nickel metal reacts with silver nitrate solution according to the following balanced equation. Ni + 2 AgNO3 -----> 2 Ag + Ni(NO3)2 If 15.32 grams of nickel reacts with an excess of silver nitrate solution, calculate the mass of silver produced. 14. How many grams of CO2 are produced when 23 grams of C2H5OH are burned? 15. O 2: 3/8 moles were present when the experiment began. All of the O 2 was consumed during the reaction. Thus, 0 g of O 2 remains. CO 2: 3/16 moles were produced by the reaction. This is equivalent to 8.25 g of CO 2. H 2 O: 3/8 moles were produced by the reaction. This is equivalent to 6.75 g of H 2 O.
