Electrolytic reactions, like other chemical reactions, are not 100% efficient. In a copper purification apparatus depositing Cu from a CuSO4 solution, operation for 5.44 hours at a constant current of 6.74 A deposits 38.8 g of Cu metal. What is the efficiency?
Two methods for determining Hg in coal fly ash using atomic absorption were used to see if both methods would give the same results. In the first method only HNO3 is used for digestion,
Rewrite the following unbalanced equations, changing them into balanced net ionic equations (assume that all reactions are in water solutions)
Draw the skeletal structure of meso-2,6-diaminopimelic acid (meso-2,6-diaminoheptanedioic acid). (Show one wedge bond, one dashed bond, and two sticks attached to the chiral carbon.
The force to push electrons through a battery comes from (a) the energy levels of the electrolyte (b) the intrinsic work function difference of two different metals (c) from electricity (d) an unknown source of energy
Antimony is the only potential interferent, as it reacts similarly to arsenic and produces a similar silvery-black film; however, antimony does not dissolve in a solution of sodium hypochlorite, but arsenic does. Therefore, the completion of the M..
The Kb of 2,4,6-trimethylpyridine is 2.7x10-7 I've really been struggling with this stuff because i've been out of school sick, if there is any way that the steps can be shown in a more broad spectrum instead of ever little detail that would be ap..
Calculate the concentration of Cu2+ in a solution prepared by adding 4.9×10^?3mol of CuSO4 to 0.480L of 0.35M NH3.
