A galvanic cell is constructed with a silver-silver chloride electrode, and a nickel strip immersed in a beaker containing 1.56 x 10-2 M solution of NiCl2. Determine the balanced cell reaction and calculate the potential of the cell. Enter in Volts (assume temp of 25 C) AgCl + e- ---> Ag + Cl- [.22V]
How can you tell that Cobalt(II) iodide is a binary ionic compound formed by a transition metal with more than one ionic charge?
A sample of 0.255 mole of gas has a volume of 748 mL at 28°C. Calculate the pressure of this gas. (R= 0.0821 L · K)
Conductivities are often measured by comparing the resistance of a cell filled with the sample to its resistance when filled with some standard solution, such as aqueous potassium chloride. The conductivity of water is 76 mS m^?1 at 25°C
Regiochemistry and stereochemistry in diels-alder reactions, How does one predict which regioisomer forms as the major product when more than one product can form? How does the dienophile affect the stereochemistry of the product?
produces an alcohol isomeric to one obtained by hydroboration-oxidation of the same alkene. Reduction of the alkene affords the compound C5H12, while ozonolysis yields an aldehyde, CH3CHO, as one of the products. Deduce the structure of the alkene..
Briefly sketch the major components of the FTIR, showing the pathway of the IR radiation among the components.
The most common source of copper (Cu) is the mineral chalcopyrite (CuFeS2). How many kilograms of chalcopyrite must be mined to obtain 355g of pure Cu
The maximum # of stereoisomers that are possible for a given molecule can be determined from the formula, 2^n, where n is the nubmer of stereocenters in the molecule.
