A Mg / Mg2+ // 2H+ / H2 galvanic cell generates a current of 2.15 x 10^-2 amperes for 205 minutes and in the process 29.9L mL of hydrogen at STP are collected. Calculate the values of Avogadro's number and the Faraday assuming the charge in an electron is 1.602 x 10^-19 coulombs/electron. Also calculate the mass the magnesium anode have lost during the process. The answers will be a number and please show the work so I can figure out how you get the answer.
A 30.00 mL volume of a weak acid, HA, (Ka = 3.8 x 10^-6) is titrated with 39.00 mL of 0.0958 M NaOH to the equivalence point. What is the pH of the analyte solution before any base is added to it

If you have 400mL of .5 M NH3, how many moles of .47 M HCl must be added to the ammonia solution to reach the equivalence point.
The standard cell potential for the electrochemical reaction is 1.10V. Calculate the cell potential if the concentration of zinc ion and copper ion are 0.050M and 5.0M respectively at room temp.
calculate the molar mass of the acid. B. After 10.00 mL of base had been added during the titration, the pH was found to be 5.87. What is the Ka of the unknown acid
A gaseous reaction occurs at a constant pressure of 50atm and releases 61.5kJ of heat. Before the reaction, the volume of the system was 7.00L. After the reaction, the volume of the system was 2.60L.
The critical constants of ethane are Pc = 48.20 atm, Vc = 148 (cm^3)/mol, and Tc = 305.4 K. Calculate the van der Waals parameters of the gas, and estimate the radius of the molecules.
When heated to 350 degrees C at 0.950 atm, the ammonium nitrate decomposes to produce nitrogen, water, and oxygen gases; 2NH4NO3(s) delta--->2N2(g)+4H2O(g)+O2(g):
They provide an alternative path for protons to re-enter the mitochondrial matrix, so ATP synthesis decreases. Electron flow and proton pumping are not inhibited.
