Chemistry I (Science Majors) (CHEM-141... Ć Malachite is a green copper mineral with the formula Cu₂CO3(OH)2. It can be converted into copper metal in a number of ways. One method extracts the metal by reacting the malachite with sulfuric acid to form CuSO4, and then adding iron to the CuSO4 solution which, after they react, forms FeSO4 and copper metal. The balanced chemical reactions are: Cu₂CO3(OH)2 (s) + 2 H₂SO4 (aq) →2 CuSO4 (aq) + 3 H₂O (1) + CO₂ (g) CuSO4 (aq) + Fe (s) →FeSO4 (aq) + Cu (s) If the final solution is dried, and 3.28 g of iron sulfate is collected, how many grams of malachite were originally used?

Treat your data sets independently. Enter your data in two columns in a spreadsheet. Your goal is to plot In K vs. 1/T (remember to use the absolute temperature). To determine K, you need to calculate the concentrations of all species that appear in the equilibrium expression. Do this as follows: [COC142-]: Use Beer's Law to calculate this concentration ( = 572 L mol-1 cm-1). However, you need to "adjust" your measured absorbance. Since both compounds absorb at 692 nm, not all of the light absorbed is due to the blue, chloride species. A small amount is due to the pink, aquo complex. Fortunately, this is a small amount, but it becomes important when the concentration of the chloro complex is very low. To compensate, divide the absorbance of the [Co(H2O)6]2+ at 511 nm by 29 ( this is the ratio of the molar absorptivity of this complex at 512 nm to that at 692 nm) and subtract this value from every absorbance measurement in your data set.* Use this "adjusted" absorbance to calculate the…

Select one answer for each question. For each question, the response write the rationale for selection as supportive. In a dynamic Brownian movement of particles in a sample solution, which of the following factor will fundamentally apply? A.Larger particles will move slower only in the beginning of the process, due to the presence of the smaller particles in the environment. B.Smaller particles will move rapidly based upon their own mass, and under the influence of solvent molecules. C.Both larger and smaller particles move at the same speed motion.
