They say their research shows, for the first time, that caffeine, catechols, and chemical-substances called N-alkanoly-5-hydroxtryptamides stimulate molecular mechanisms of stomach acid secretion in human stomach cells.
Page 1 of 7. Specific Heat. Objectives. In this lab you will. â¢ measure the specific heats of aluminum and lead using a calorimeter and the. Vernier Temperature Sensor. â¢ observe how the temperature of your system reaches equilibrium in real time. â¢ plot your data and analyze it using the Vernier Logger Proâ¢ software.
Calculate the molar masses of Al2o3 and Na3AlF6. I have the answer for this question b/c it comes in my book but I would really like to know how to do this... show more Aluminum metal is produced by passing an electric current through a solution of aluminum oxide ( Al2o3), dissolved in molten cryolite (Na3AlF6). Calculate the molar masses of Al2o3 and Na3AlF6.
