In the presence of of NH3, Cu^2+ forms the complex ion Cu(NH3)4^2+. Explain if the equilibrium concentrations of Cu^2+ and Cu(NH3)4^2+ are 1.8x10^-17M and 1.0x10^-3M, respectively, in a 1.5M NH3 solution, Compute the value for the overall constant of Cu(NH3)4^2+ Cu^2+(aq) + 4NH3 (aq) <=> Cu(NH3)4^2+(aq) Koverall =?
the addition of bromine to an equimolar mixture of cis- and trans-2-butene generates only three stereoisomers. Explain.
Discuss the typical features of a calomel electrode and a silver - silver chloride electrode. What are their standard half cell potentials?
A 5.01 g sample containing solid potassium chlorate and other inert impurities was heated in a test tube. The potassium chlorate in the sample completely decomposed into potassium chloride and oxygen gas.
Calculate the cell potential (Ecell) of an electrochemical cell with Mg/Mg2+ and Fe/Fe2+ electrodes. [Mg2+] = 0.200 M and [Fe2+] = 0.050 M.
At this point in the titration the system reches equilibrium and therefore Qsp for silver chromate is equal to Ksp of silver chromate and Qsp for silver chloride is equal to Ksp for AgCl. 1. Cal the equilibrium concentration for the chromate ion [C..
calculate (a)molality? (b)molarity of NaCl? (c) What is the mass/mass and remove the most loosely held e- from a gaseous atom in a ground state
Pure colored substances mostly exhibit a single peak (i.e. max) in the visible; therefore the simple rules of complementary colors apply. Mixtures are a little more complicated.
Two peaks on chromatogram have k1= 3.1 and k2= 4.9. Column efficiency is 2000 theoretical plates, void volume is 1mL. calculate the resolution between these compounds.
For each of the following give the sublevel designation (name of orbital), the allowable ml values, and the number of orbitals- a. n = 5, l = 3 c. n = 2, l = 0 b. n = 3, l = 1 d. n = 6, l = 2
A certain protein was found to contain 0.412% manganese by mass. Determine the minimum molecular mass of the protein.
How much PV work is done in kilojoules delta E if 89.5 g of ethylene and 125 g of HCL are allowed to react at atmostphere pressure and volume change is -71.5 L
