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.
Specific Heat of water = 4.184 J g-1 C-. Answers: Mass water x 1 cal (-15) Mass water = 2333 G.-. Question: We had to do a lab for the IB programe...and we (my group) decided to test the effect Iron II would have on two different types of bleach (Hydrogen Peroxide and Sodium Hypochlorite).ot quite sure of what scientific idea you are trying to test with this. You said we (my group) decided to test the effect Iron II would have on two different types of bleach (Hydrogen Peroxide and Sodium Hypochlorite).
