A stock solution is prepared by adding 21 mL of 1 M AlCl3 to enough water to make 76 mL. What is the Cl- concentration of 40 mL of the stock solution?
Reaction of AsCl3 with Cl2 at low temperature yields a product, believed to be AsCl5, which shows Raman bands at 437,369, 295, 220,213, and 3cm-1. Detailed analysis of the 369 and 295 cm-1 bands show them to arise from totally symmetric modes.
Consider the reaction A+2B = C whose rate at 25 C was measured using three different sets of initial concentrations as listed in the following table: Trial Rate 1 0.25 0.010 7.5×10?4 2 0.25 0.020 1.5×10?3 3 0.50 0.010 3.0×10?3 Part A What is the r..
