Transcribed Image Text:Results: Part B: Dissolving NaOH
AH)--3971.17 J mol
Part C NaOH(aq) + HCI(aq) AH; --1453.4J mol
AH-4815.3 J mol
Part D: NaOH() + HC(aq) prodicted value from Hew's Law: -5424 57 J mol"
Given the experimental uncertainty of these results is 10000 J mol", which of the following would be the correet conclusion from your results
O My results confifm Hess's Law because the difference betwoen the predicted and observed AHy is greater than experimental uncertainty
O My results confirm Hess's Law because the difference between the predicted and observed AH3 is less than experimental uncertainty
O My results do not confirm Hess's Law because the difference between the predicted and observed AH, is greater than experimental uncertainty
O My results do not confirm Hess's Law because the difference between the predicted and observed AH; is less than experimental unecertainty
