The laboratory exercise calls for transferring 11 – 12 mmol of copper(II) chloride dihydrate to the 125mL Erlenmeyer flask. Determine the molar mass for this reagent (show your work, compare this result to a suitable reference source properly citing the source) and the mass needed to obtain the desired amount. What is the theoretical yield of the synthesis of bis(acetylacetonato)copper(II) if 4.1962g of the starting material was transferred to the Erlenmeyer flask? (Hint: determine the stoichiometric equivalencies of the reagents...

Using the correct formula for the green crystals write a balanced chemical equation for their synthesis. The reactants were iron (III) chloride, potassium oxalate and water. A second product of the synthesis is potassium chloride. Note: the waters of hydration in the iron(III) chloride, and potassium oxalate should not be shown. Include phase labels. Using the masses of iron (III) chloride hexahydrate and potassium oxalate monohydrate from Data Table A, calculate the theoretical yield of green crystals. This is a...
