Question

a.) C+ 2H2 = CH4
From the equations:
1. С + О23D СО2
AH = -393.51 kJ
2. H2 + % O2 = H20
AH = -285.83 kJ
3. CH4 + 202 = CO2 +H2O
AH = -890.37 kJ
b.) 2N203 = 2N2 + 302
From the equations:
1. N203= NO + NO2
AH = 39.7 kJ
2. ½ N2 + ½ O2 = NO
AH = 90.4 kJ
3. ½ N2 + O2 = NO2
AH = 33.8 kJ

= O PRINCIPLES OF ORGANIC CHEMISTRY Identifying rigid parts of an acyclic organic molecule In the actual molecule of which this is a Lewis structure, which of the labeled distances can change? marked O B H C L O O unmarked H C O C H H 00.. X ▬▬— You can click the "unmarked" tab to see the molecule without any of the distances marked. List all the distances that can change. For example, suppose all the distances were measured at a certain time, and again 0.1s later. If distance A might be 50% bigger or smaller the second time, but all the other distances are certain to be the same, you should write "A". If A and B might be different the second time, but no other distances, you would write "A, B". And so on.
