A voltaic cell is made by placing an iron electrode in a compartment in which the Fe2+ concentration is 4.5 x 10^-5 M and by placing a Pt electrode in the other compartment, in which the H+ concentration is 3.50 M and P(subscript H2) = 1.00 atm. The Fe2+/Fe half-cell reduction potential is -0.44 V and the H+/H2 half-cell reduction potential is 0.00V. What is E for the cell at the concentrations given?
a. 0.28 Vb. 0.44 Vc. 0.58 Vd. 0.60 Ve. 0.10 V
The decomposition of hydrogen peroxide is first order in H2O2. 2H2O2 -----> 2H2O + O2 The rate constant for this reaction at 20 C is 1.8 * 10^-5 s^-1
A certain first-order reaction has a rate constant of 3.40×10?3s^-1 . How long will it take for the reactant concentration to drop to 1/8 of its initial value
purified a new protein and find that it contains 0.154 percent Mn. Assuming that there are three atoms of manganese per molecule of protein, what is the molar mass of the protein
Co(H2O)62+(aq)+4Cl?(aq), which interconverts the blue CoCl42? ion and the pink Co(H2O)62+ ion. Will the equilibrium concentration of CoCl42? increase or decrease when the following changes occur?
At 0.0 degrees C, if the volume of air is 1.5 mL and the pressure of the atmosphere that day is 685 mmHg, what is the number of moles of air?
HNO3 has 2 dissociating ions whereas Al(NO3)3 has 4, which should result in a higher conductance value. Would this have something to do with aluminum nitrate being paired with water as a solid?
