Experiment B2‚ Heats of Combustion – The Bomb Calorimeter. Objectives: To calibrate a bomb calorimeter by the combustion of benzoic acid. Then to use the calibrated calorimeter to measure the heat of combustion of naphthalene and calculate the heat of formation of naphthalene. Theory: q = C.ΔTBA C = q / ΔTBA Moles = mass / Mr ΔŪ = ΔU / moles ΔHoc‚298 = ΔŪoc‚298 + PDV = ΔŪoc‚298 + RTΔn C10H8 (s) + 12O2 (g) 10CO2 (g) + 4H2O (l) ΔHoc‚298 = - 1

Lab #6: Assessment Worksheet 1. Why is it important to prioritize your IT infrastructure risks‚ threats‚ and vulnerabilities? Because you need to know which is most important and which is negligible. In some cases‚ protecting your infrastructure from a high priority threat is more important and so you may want to protect against that even if it leaves you vulnerable to low priority threats. This mainly just shows you which areas need your attention the most. 2. Based on your executive summary
