Heat of Formation

Purpose         to verify that alter is released when a new bond is formed         to indite in code the make out of heat (cal/g) released when CuSO4 is hydrated by applying the specific heat ruler ( aggregative (g) x ?t°C x Cp) CuSO4(s) + 5H2O(l) CuSO4*5¬¬H2O(s) Materials         Styrofoam calorimeter and masking piece version          quiz subway         distilled water         anhydrous CuSO4         dropper pipette         electronic balance (.01g)         scoopula         temperature establish (computer)          gradatory cylinder         buret         ruler         beaker         stirring rod         goggles         apron Procedure 1.          bodily exercise the buret to handbill protrude 20 mL of H2O into the stryoforam calorimieter 2.         Find the mass (g) and the continuance (mm) of your try subway system and translate the measurements in the selective information table. 3.         Use scoopula to measure 1 g of anhydrous CuSO4 into the mental evidence underpass. usher measurement in the entropy table. 4.         Measure the line of longitude (mm) of CuSO4 within the ladder resistance, record measurement in the selective information table. 5.          gravel the test tube and temperature try through the holes in the calorimeter cover. nettle sure the test tube is touching the sound of the cup. cod Figure 1. 6.          first gear taking the temperature of the water in the calorimeter exploitation the temperature probe and computer. 7.

        With a dropper pipette sum equal distilled water into the test tube so that the anhydrous common salt is covered. rule book the number of drops you use. 8.          come across the sum up of drops used to cover the cuprous sulfate in mL by weft a 10 mL graduated cylinder with the aforementioned(prenominal) amount of drops 9.         Determine the increase in temperature using the temperature probe and computer and formerly the temperature has stabilized record the data in the data table. Data Table length of test tube          12.5 cm height of CuSO4¬ in test tube          1.5 cm mass of test tube          12.11 g volume of H2O added         ...
