Heat of Reaction.

>>> mania of Reaction Aim: To determine the doodad fire of reaction of NaOH with HCl ApparatusMaterials: polyethylene Cup, Thermometer, Measuring Cylinder, NaOH, HCl. Procedure: (1) 25cm of HCl was dictated in polythene cup, (2) HCl was left to stand for 5 minutes and then the temperature was taken (3) travel 1-2 was repeat with NaOH instead of HCl, (4) NaOH was added to HCl in polythene cup and touched for 5minutes and the highest temperature the liquid rose to was recorded. Results: sign temperature of NaOH - 32? Initial temperature of HCl - 31? Final temperature of smorgasbord - 38? Temperature wage encouragement for NaOH = 6? Temperature rise for HCl = 7? Volume of mixture = 50cm crowd of stem = 50g 1 cm of solution has a mass of 1g Number of moles present in 25cm of NaOH = .0025moles Heat produced = 1365KJ Calculations: (1) Mass of 1cm of solution = 1g since the dumbness of the solution is 1g per cm, (2) Number of moles of NaOH = chroma incmxconcentration in moles per dm 1000 cm = (25 x .1)/1000 = .0025moles (3) Heat produced = MC?? of NaOH+ MC?? of HCl = .

025kg X 4200 X (38?- 32?) NaOH = 630J (NaOH) = 025kg X 4200 X (38?- 31?) HCl = 735J (HCl) = 630J (NaOH) + 735J (HCl) = 1365J Conclusion: An exoergic reaction takes place when NaOH is miscellaneous with HCl. The amount of kindle produced when .0025 moles of NaOH is miscellaneous which .0025 Moles of HCl is equal to 1365J and the amount of heat that forget be produced when 1mole of NaOH reacts with 1mole of HCL will be equal to ((1 moles .1mole) X 1356j), 546KJ superb lab. Well organized. swell conclusion. And excellent calculations!! Needs sources If you insufficiency to get a skinny essay, order it on our website: Orderessay
