An experimental cell is set up such that one half cell contains a solid silver electrode dipping into a saturated solution of silver oxalate. The oxalate ion comes from added oxalate so that equilibrium concentration of oxalate ions is 0.50 M. This half-cell is connected to a standard hydrogen electrode (SHE) half-cell. The measured potential for this cell is 0.476 V at 25C. What is the experimental value of the solubility product constant for silver oxalate?
What is the pH of the resulting solution when 17.25 mL of 18.00 M HCl is added to a 1.9 liter solution that has 0.74 M cyanide ion CN- and 0.85 M hydrocyanic acid HCN
If a certain gas occupies a volume of 20 L when the applied pressure is 10 atm, find the pressure when the gas occupies a volume of 5.0 L.
A tetrahedral site in a close-packed lattice is formed by four spheres at the corners of a regular tetrahedron. This is equivalent to placing the spheres at alternate corners of a cube. In such a close-packed arrangement the spheres are in contact..
Draw the structures of the two carbocation intermediates that might form during the reaction of the alkene (below) with HCl. If the two carbocations differ in stability, draw a reaction arrow from the less stable to the more stable.

A 48.0-L gas cylinder contains 249 mol of H2 gas at 298 K. What is the pressure inside the cylinder.
Problem- 10.00 mL of 1.000M HA (a weak acid) was mixed with a 5.00mL NaOH. Then the mixture was diluted to 50.0mL with water. The pH of the solution reads 5.00. 1. Calculate moles of each. What is the limiting reactant
Nitroglycerin is explosive, decomposing violently via the reaction: 4 C3H5N3O9 (s) ? 12 CO2 (g) + 6 N2 (g) + 10 H2O (g) + O2 (g) If 25.0g of nitroglycerin explodes in a 10.0 L rigid container, calculate the total pressure of all gasses present and..
Problem- A 35.0-L vessel at 700 K initially contains HI(g) at a pressure of 6.90 atm; at equilibrium, it is found that the partial pressure of H2(g) is 0.668 atm.
The iron content of hemoglobin can be determined by converting the iron to Fe2+ and titrating using MnO4 -. A 5.0 g sample of hemoglobin requires 21.6 mL of 0.00310 M potassium permanganate. What is the percent of iron in the hemoglobin sample?
