THERMOCHEMISTRY & HESS'S LAW AP KIT\r\n
\r\nHess's Law of enthalpy, based on the observed data for two \r\nreactions, is the basis for this experiment. By measuring \r\nthe temperatures of the reaction in a calorimeter, then \r\nanalyzing the data, the enthalpy of each reaction can be \r\ncalculated. The small amount of chemicals makes for faster \r\nprep time, easier clean up, and fewer disposal worries. \r\nAll experiments have been prepared and bench tested under \r\nthe guidance of AP chemistry teachers. Lab includes \r\nchemicals, an instructional guide, the appropriate MSDS, \r\nand enough materials for fifteen set-ups. UPS Hazard Charge Applies Pricing includes a hazardous material shipping charge.\r\n
\r\n Chemicals included:\r\n
\r\n 8 ea 250 \r\nml Hydrochloric Acid, 2M/2N Soln; 250 ml Sodium Hydroxide, \r\n2M/2N Soln\r\n
\r\n 2 ea 500 ml \r\nAmmonium Chloride, 2M Soln; 500 ml Ammonium Hydroxide, \r\n2M Soln\r\n
\r\nAll twenty-two AP Chemistry Kits are available \r\nindividually or as a complete set. See No.800000 for \r\nmore information.\r\n
