Document Summary
Multiple choice questions: potassium dichromate, k2cr2o7, is used in tanning leather, decorating porcelain, and water proofing fabrics. In the photoelectric effect, a photon with an energy of 5. 3 x 10-19 j strikes an electron in a metal. Of this energy, 3. 6 x 10-19 j is the minimum energy required for the electron to escape from the metal. The remaining energy appears as kinetic energy of the photoelectron. M and m" represent cations and a represents the anions. What is the empirical forumula of the mineral: mm"a, mm"a3, m2m"a3, m8m"a6, cannot be determined, a certain solid metallic element has a density 7. 87 g/cm3 and a molar mass of 55. 85 g/mol. It crystallizes with a cubic unit cell, with an edge length of 286. 7 pm. What is the molar mass of lysine if 750. 0 ml of a solution containing 8. 60 g of lysine has an osmotic pressure of 1. 918 atm: 110. g/mol, 146 g/mol, 220. g/mol, 1340 g/mol, 1780 g/mol.
