Data for ammonia: Molar mass = 17.03 g mol1 AvapH = 23.35 kJ mol-1 at the standard boiling point, T, = 240. K Molar heat capacity (in J K´1mol^1) of ammonia: 80.1 (liquid) and 36.9 (gas) What is the vapor pressure (in bar) of ammonia at 200 K? For this question, assume AvapHº does not vary with temperature - use the value at the standard boiling point. 0.132 0.156 0.0963 1.00 What is the vapor pressure (in bar) of a 1.00 mol kg1 solution of sodium chloride in ammonia at 240 K? 0.924 0.857 0.966 1.00 What is the boiling point (in K) of a 1.00 mol kg1 solution of sodium chloride in ammonia? 240.7 243.3 236.1 240.0

3. Classify the following as a lipid, carbohydrate, or amino acid: (EOCQ 58) CH,OC(CH,)12CH, CHOC(CH,),,CH, CH,0C(CH,),CH=CH(CH,),CH, a.

What is the properIUPAC name for this

-Understand and be able to identify different interactions that factor into peptide/protein folding (e.g. hydrogen bonding, salt bridge interactions, disulfide bonding. Be able to predict these interactions given a peptide structure. -Understand basic molecular geometry in a peptide. What is the bond angle between amide N, C, and O atoms? Why is the angle like this?
