A voltaic cell is constructed with two silver-silver chloride electrodes, where the half-reaction isAgCl (s) + e-? Ag (s) + Cl- (aq) E° = +0.222 V
The concentrations of chloride ion in the two compartments are 0.0222 M and 2.22 M, respectively.
The cell emf is _______ V.
How can one make five serial solutions of a stock solution of silver ion if the stock solution has a concentration of 0.100M, make a table of the volumes and solutions
what would be the chemical equation to this problem? In an investigation of the reaction between copper(II) ions, Cu2+, and hydrazine, N2H4, in alkaline conditions the following observations were made: 25 mL of a solution containing 25 g/L CuSO4.5..
If Ka is 1.85 x 10^-5 for acetic acid, calculate the pH at one half the equivalence point and at the equivalence point for a titration of 50 mL of 0.100 M acetic acid with 0.100 M NaOH.
A 51-kg person drinks 390. g of milk, which has a "caloric" value of approximately 3.0 kJ g-1. If only 16% of the energy in milk is converted to mechanical work, how high (in meters) can the person climb based on this energy intake?
Compare and contrast the nitrogen requirements of microorganisms and higher forms of life, describing how their respective requirements are met
