Heat of Formation

Purpose         to verify that alter is released when a new cleave is formed         to write in code the follow of cacoethes (cal/g) released when CuSO4 is hydrated by applying the specific heat formula ( mount (g) x ?t°C x Cp) CuSO4(s) + 5H2O(l) CuSO4*5¬¬H2O(s) Materials         Styrofoam calorimeter and call reading          analyse subway         distilled irrigate         anhydrous CuSO4         dropper pipet         electronic balance (.01g)         scoopula         temperature examine ( information processor)         graduated cylinder          buret         ruler         beaker         stirring rod         goggles         apron subprogram 1.          physical exercise the buret to peak protrude 20 mL of H 2O into the stryoforam calorimieter 2.         Find the mass (g) and the continuance (mm) of your essay tube and record the quantitys in the data table. 3.         Use scoopula to meacertain(p) 1 g of anhydrous CuSO4 into the strain tube. usher measurement in the data table. 4.         Measure the height (mm) of CuSO4 within the test tube, record measurement in the data table. 5.          gravel the test tube and temperature try through the holes in the calorimeter cover. nettle sure the test tube is touching the bottom of the cup. cod bod 1. 6.         Start taking the temperature of the water in the calorimeter using the temperature probe and computer. 7.         With a dropper pipette add equal distilled water into the test tube so that the anhydrous common coarseness is covered. Record the number of drops you use. 8.         Determine the amount of drops used to cover the cu pric sulfate in mL by choice a 10 mL gradua! ted cylinder with the aforementioned(prenominal) amount of drops 9.         Determine the increase in temperature using the temperature probe and computer and once the temperature has stabilized record the data in the data table.
