You are in lab and ready to mix a beaker containing a solution of sodium cyanide with a beaker containing a solution of cobalt (III) acetate. You mix 45.0 mL of a 6.32 M solution of the sodium cyanide with an excess amount of cobalt (III) acetate. 1. Write out the balanced molecular reaction (including all physical states) for this reaction. 2. Calculate the amount of moles of sodium cyanide that was added into the mixture. 3. Calculate the minimum amount of moles of cobalt (III) acetate required to completely react the sodium cyanide. 4. Calculate the mass, in grams, of the solid produced from the reaction.
The solubility product constant for a certain metal fluoride, MF2 is Ksp = 1.2 × 10−6. Its molar mass is ℳ = 175.90 g/mol. What is its solubility in mol/L?

QUESTION #1: TOPIC: Solving for a reactant in solution One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(II) carbonate, in concentrated sulfuric acid. The sulfuric acid reacts with the copper(II) carbonate to produce a blue solution of copper(II) sulfate. Scrap iron is then added to this solution, and pure copper metal precipitates out because of the following chemical reaction: Fe(s) +CuSO4(aq) →Cu(s) +FeSO4(aq) Suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. He adds powdered iron to a 350. mL copper(II) sulfate sample from the plant until no more copper will precipitate. He then washes, dries, and weighs the precipitate, and finds that it has a mass of 93. mg. Calculate the original concentration of copper(II) sulfate in the sample. Round your answer to 2 significant digits. ? g/L QUESTION#2: TOPIC: Limiting reactants…
13. A chemistry student offers a possible improvement to this lab. Since one goal of this lab is to determine the mass of the precipitate produced, wouldn't it be possible to measure the mass of an empty beaker, mix the solutions, and boil off the water until it is entirely evaporated, leaving only solid behind? Then the beaker with the precipitate could be weighed, and the difference between this mass and that of the empty beaker would be the mass of the precipitate. This would eliminate the need for the filtration step. Explain why this is a poor suggestion. Remember to check your reasoning on this question and all other questions with your instructor.
