Chemical reaction Essay

1.Determine the heat content swop for NaOH (s) + HCl (aq) NaCl (aq) + H2O(l) use Hesss Law.a. Write the balanced chemical reaction and enthalpy change for demote I (1pt) b. Write the balanced chemical reaction and enthalpy change for Part II (1pt) c. Calculate the enthalpy change using Hesss Law. Refer to the lesson for an example of Hesss Law. (2pt) 2.If the accepted enthalpy change cheer for the dissolving of sodium hydroxide in water is 44.2 kilojoules per mole, determine the share misunderstanding of the experimental value that you calculated in Part I. luff your work. (experimental substantial value) / actual value 100 %3.If the accepted heat of reaction for the neutralization of hydrochloric acid with sodium hydroxide is 56.0 kilojoules per mole, determine the percent error of the experimental value that you calculated in Part II. Show your work. (experimental actual value) / actual value 100 %4.Using the accepted values of the processes youve examined, would you r estimation of the enthalpy change for the reaction of solid sodium hydroxide in sedimentary hydrochloric acid change from the prediction you made in question peerless? Explain your answer in complete sentences. 5.Give a detailed explanation, using what you know about bonds and forces of attraction, for the enthalpy changes you observed in parts I and II of this lab. Explain your answer in complete sentences.
