Unformatted text preview: 5 45 .1 20.90 21.81 .91 We found that our initil tempertature was very consistant and often was the same temperature as the experiment before it. The change in temperature seemed to increase till the the volume of NaClO was 35 mL. after that, the temperature decreased to the last test. Uncertainty: The could be many uncertainties in this experiment. We could have calibrated the temperature probe wrong, of not have gotten all the material off the probe between each use. We also might not have added the right amount of NaCl0 to the experiment causing more uncertainty. Definitions: stoichiometric coefficient- represents the degree to which a chemical species participates in a reaction. Mole Fraction: The ration of the number of moles of a given component of a mixture to the total number of moles of all the components. Molarity: the number of moles of a solute per liter of solution....
