The experiment was done twice in trial 1 and 2. First‚ in the first trial‚ the crucible with lid was measured on a balance and the mass of them was recorded in grams which is m of clean crucible = 22.89g . This was followed by weighing the crucible with 0.3 g of Magnesium on a balance. The total mass of mg with the crucible was recorded which was m total mass mg + Crucible = 23.19g. Then the magnesium was heated using a Bunsen burner‚ and we put the crucible with Mg on a clay triangle using tongs

Experiment 1: Calorimetry Nadya Patrica E. Sauza‚ Jelica D. Estacio Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines Results and Discussion Eight Styrofoam ball calorimeters were calibrated. Five milliliters of 1M hydrochloric acid (HCl) was reacted with 10 ml of 1M sodium hydroxide (NaOH) in each calorimeter. The temperature before and after the reaction were recorded; the change in temperature (∆T) was calculated by subtracting the initial temperature

CALCULATIONS Determining the amount Limiting Reagent used. nlimiting reagent = Molarity x Volume or Mass / Molar Mass Example: Limiting reagent is 5mL of 1.0 M HCl nlimiting reagent = Molarity x Volume nlimiting reagent = (1.0 [mol/L]) x 0.005 [L]) = 0.005 mol Determining the qrxn and qcal. qrxn + qcal = 0 -qrxn = qcal qrxn = ΔHrxn x nlimiting reagent qcal = Ccal ΔT qrxn = - Ccal ΔT + mcsolid ΔT (note: only if there is a precipitate formed in the reaction)

This is most easily done by first identifying the strong acids that have the lowest pH‚ the strong bases that have the highest pH‚ and the neutral solutions that have a pH near 7. The weak acids will have a pH between

To obtain the values for V_∅^∞ given in Table 6‚ they were fitted to equation 7. Note that prior measurements of density on poly(ethylene glycol) + water should perform to calculate the values of V_∅^∞ for the polymer. Table 3 has shown these empirical values for different molalities of poly(ethylene
