This is PSU univiversity Chem 110 lab report. Please answer question 2. CHEM 111 Calculation of All for NH C) 1. Complete the equation for the chemical reaction representing t the formatios of SH,C 2. Using Hess. Law, combee your AH of fornation for NIgCs). Show your work explicidy age AH re its hom Parts IA and IB-the- Anata to 9.45 -45.77 -92.31 -35.40 72.84 Report the calculated value of AH of NH4Cl(s), using your experimental data. NOTE: include proper units and sig Aigs. 3. From a table of thermodynamic data in the Chem 110 textbook (refer to Appendix VIlI of the Lab Manual for a specific reference) look up the value of alf ofNH4Cds). -215·u Write the mathematical equation for calculating percent error and show specifically how you use that equation to calculate the percent error between your calculated result and the textook value ftH: ofNH4C(s). 4.
