A student dissolved 0.44g of copper wire and followed all steps described in the copper cycle experiment to obtain solid copper. After performing the series of reactions a student weighed a total mass of 24.61g on the scale. This mass included the filter paper mass of 0.23g and the watch glass of 24.19g. Calculate the % recovery for this experiment. %recovery= final mass of copper grams divided by initial mass of copper grams

Lab procedure: This laboratory exercise involves the use of dilute sulfuric acid (H2SO4) to leach copper from a synthetic copper-containing ore, malachite. This technique is known in the mining industry as solution mining. The soluble copper is then filtered to remove unreacted ore (the residue) from the filtrate containing the copper+2 ion. The copper in the filtrate is then treated with metallic magnesium to precipitate the copper as the familiar orange-brown metal. This copper is dried and weighed. From these...

Please answer the following questions/fill in the data tables based on the following experiment. EXPERIMENTAL PROCEDURE: Place sodium hydroxide (2.500 g) in a 100 mL Erlenmeyer flask and add water (25.0 mL) and ethanol (20.0 mL). Add a magnetic stirrer bar and stir until all the NaOH has dissolved. To a second reaction vessel, add benzaldehyde (2.650 g, 0.025 mol) and acetone (0.725 g, 0.0125 mol). Add approximately half of the aldehyde-ketone solution to the sodium hydroxide solution, and stir...

A student dissolved a piece of copper wire, then converted it to Cuo, filtered the Cuo from solution, and determined the mass of the Cuo. The CuO was then dissolved, reduced to copper metal, and recovered. Calculate the percent yield for CuO and Cu from the following data: UULUcceeeeeeeee Mass of the copper wire Mass of filter paper Mass of filter paper + CuO Mass of filter paper Mass of filter paper + Cu 0.260 g 0.5258 0.834 g 0.490...
