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 24.66g on the scale. This mass included the filter paper mass of 0.23g and the watch glass of 24.25g. Calculate the % recovery for this experiment.
Homework Answers
After experimentass of copper = 24.66 - ( 24.25 + 0.23)
= 0.18 grams
% recovery = (final mass / initial mass )*100
= (0.18 / 0.44)*100
= 40.9%

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

Mole Ratios Copper(II) chloride (CuCl,; 0.98 g) was dissolved in water and a piece of aluminum wire (Al: 056 p) was placed in the sbittion. The blue color due to copper(II) chloride soon faded and a red precipitate of solid copper was observed. After the blue color had disappeared completely, the leftover aluminum wire was removed from the solution and weighed. The mass of the leftover aluminum wire was 0,43g 1. Calculate the number of...

Water molecules evaporated when the solid was heated until it turned brown then the sample was dissolved in water to react with a coil of aluminum wire and copper deposited on the coil. The student weight the initial material in a beaker before and after drying, and weight the deposited dried copper powder...
