Experiment 12: Calorimetry and Hess’s Law Purpose: The purpose of this lab is to determine the enthalpy of reaction for the burning of one mole of magnesium in oxygen. Although the reaction is exothermic‚ the ∆HRXN will be determined by using calorimetry and then using Hess’s Law to manipulate the data collected to yield the answer needed. Procedures: Dillon‚ Stephanie. “ Calorimetry and Hess’s Law.” Laboratory Manual. Pearson Publishing‚ 2012‚ pp.168-177. Data and Results Part A

Title: Calculating the Atomic Mass of “Pennium” Purpose: The purpose of this lab is to calculate the atomic mass of “pennium” using pennies made before 1982 and pennies made 1982 or after. Hypothesis: The atomic mass of the pennium will be the average of the average masses of a pre-1982 penny and a post 1982 penny. Procedure: 1. Obtain a bag of pennies 2. Determine the total number of pennies in the bag. Record the value. 3. Sort the pennies by date into 2 piles. One pile should consist

The study of urinary chemistry on stone forming minerals will provide a good indication of risk of stone formation. Urinary supersaturation with respect to stone-forming constituents is generally considered to be one of the causative factors in calculogenesis. Though supersaturation of stone forming salts in urine is essential‚ abundance of these salts by itself will not always result in stone formation. Various substances in the body have an effect on one or more of the stone forming processes (nucleation

(Ba(OH)2). Through the conductivity‚ the equivalence point can be determined; from there‚ the concentration of the Ba(OH)2 solution can be found. The final product of the reaction between sulfuric acid and barium hydroxide is insoluble. According to the lab manual‚ during the reaction‚ the total number of dissociated ions in solution is greatly reduced as a precipitate is formed. With the Conductivity Probe‚ the changes in conductivity of the solution will be analyzed. The collection of Ba(OH)2 precipitate
