In an electrolysis cell similar to the one employed in this experiment, a student observed that his unknown metal anode lost 0.238 g while a total volume of 84.90 mL of H2 was being produced. The temperature in the laboratory was 23°C and the barometric pressure was 621. mm Hg. You will need to look up vapor pressure of water at that temperature. Find the equivalent mass of this metal.
A chemist prepares a sample of hydrogen bromide and finds that it occupies 252 mL at 70C and 464 Torr. What volume would it occupy at 0C at the same pressure.
calculate the gasphase proton affinity of NH3. The lattice energy of NH4Cl may be estimated from Kapustinskii's formula using rN-Cl = 3.50 Å.
A buffer that contains 1.10 M base, B, and 0.700 M of its conjugate acid, BH+, has a pH of 9.250. What is the pH after 0.0050 mol of HCl
How many grams of KCl are present in 250.0 mL of a 0.125 M solution? [Use formula weight: KCl, 74.55 g/mol]
