Calorimetry: Enthalpy of Neutralization Introduction: The purpose of this lab experiment was to determine the molar concentration of the unknown HCl by using a coffee cup calorimeter. A coffee cup calorimeter is made of Styrofoam cups with a thermometer that is placed from the top and into the calorimeter to measure the temperature as the reaction happens. The Styrofoam cup used for the calorimeter creates an isolated system as it acts as a heat insulator between the cup and the surrounding

thing to wrap one’s mind around. But all of that just might be changing. We won’t get our hopes too high until fuel cells become the viable alternative that we have been told that they are‚ but we strangely have more faith in a vegetable than a science lab to revolutionize the battery. A vegetable? Yes‚ indeed. Yissum Research Development Company Ltd.‚ the technology transfer arm of the Hebrew University of Jerusalem‚ has just introduced what they’re calling "solid organic electric battery based upon

Amperometry Doug Glosup CHE 4213.002 03/18/13 Introduction: Amperometry in chemistry is the detection of ions in a solution based on electric current or changes in electric current. Another words‚ the measurement of current resulting from the electrochemical reaction at the electrode‚ is a simple means of determining the concentration of electro-active species. The type of electrochemical cell used in this experiment is a three-electrode cell. The cell consists of working‚ reference and counter

the science lab. In science‚ we would participate in a lab. One of my favorite labs was the owl pellet dissection. Owl pellets are owl throw up. In owl pellets you can find the bones of animals the owl consumed. In this lab we were to take out the bones we found in the pellet and construct the animal we found inside. Most people‚ like me‚ had a sort of rodent‚ but some people found birds in their pellet. Another one of my favorite things we did in science was the Sharpie tie dye lab in fifth grade
