D. F. Nachman Thermochemistry: An Ice Calorimeter Determination of Reaction Enthalpy 9/11/2014 Introduction: A chemical reaction often indicated by a transfer of energy measured in heat. By measuring this heat transfer in a constant pressurized environment‚ the enthalpy of the reaction can be used to infer certain information about a specific reactions reactants and products. The transfer of heat from outside sources in would be described as an endothermic reaction. Contrary‚ when

Argon (Ar) is a noble gas found in Group 0 on the periodic table. It gets its name because of its chemical inertness and comes from the Greek root ‘Argo‚’ which means lazy. This is because Argon doesn’t react well with other elements. The atomic number of Argon is 18 making it a member of the helium group of elements which are also called noble‚ or inert‚ gasses and are non reactive. Its electronic configuration is: 1s2 2s2 2p6 3s2 3p6 The outermost shell‚ shell number three‚ has a completely

neutral salt: NaCl & H2O => Na+ & Cl- & H2O Module 5- Buffers 15. An acid contributes a surplus of hydrogen ions to a solution. A base contributes a surplus of hydroxide (OH) ions to a solution. 16. Buffer solutions are solutions that resist change in Hydronium ion and the hydroxide ion concentration (and consequently pH) upon addition of small amounts of acid or base‚ or upon dilution. Buffer solutions consist of a weak acid and its conjugate base (more common) or a weak base and its conjugate

without consuming enzyme. In this experiment‚ the substrate is hydrogen peroxide. The gas pressure sensor is used because the reaction produces oxygen gas. The faster the reaction is‚ the faster the pressure will increase. Thus‚ by examining the change of pressure overtime‚ the rate will be calculated and analyzed. For this investigation‚ the initial rate of the reaction is examined. Safety precautions All enzymes are potential allergens therefore eye and skin should be avoided Wear eye protection
