Why is (a) considerably more stable than (b)?? Is it only because of resonance?
Circle the metal ion that would form a more stable complex ion with each of the following anions. a) K or Aut forms a more stable complex with H2S. b) Hg2+ or Mn2+ forms a more stable complex with H Circle the base that would form a more stable complex with the acids listed. a) CO or NH; will form a more stable complex with T13+ ions. b) H2O or PMez will form a more stable complex with Zn2+ ions.

The H2 ion is more stable (higher bond order) than H2 since it has an additional electron to produce a net lowering of energy. (consider MO theory to answer this.) False O True Question 2 Which best explains the following trend? Element b.p. (K) He 4 Ne 25 Ar 95 Kr 125 Xe 170 O dipole-dipole interaction hydrogen bonding O London dispersion forces O ion-dipole forces
Why is equatorial methylcyclohexane more stable than axial methylcyclohexane? 2.32
5. Explain why direct antigen activation of CTLs and B cells is more important than APC-initiated activa- tion in subsequent encounters with a microbe. Why is the APC-initiated pathway needed at all? 6. There are many interactions between the innate and adaptive defense systems. List as many of them as you can and explain how they work. Why are these interactions important? Are all of them beneficial? 7. What are the two ways that polysaccharides, DNA, and lipid antigens can...
1. What is a structure based explanation for why acetamide is more stable than acetone. I'm pretty sure it has to do with resonance. 2. also for question F im fairly sure it has to do with resonance again but I not sure exactly why. could someone answer and explain? F. Draw the conjugate base for each compound below and draw the appropriate structures to explain the difference in N-H acidity pKa~9.5 pKa 16 N-H N-H
need help with the content 1a) Electrons in an atom are more stable than free electrons. This is why the energy levels of electrons in atoms are negative (free electrons are defined as having an energy of zera). Calculate the energy of a hydrogen. electron in the 4" shell, in J. b) Calculate this energy in kl/mole. 2. Calculate the energy for nu1, 2, 3, and 5 as well. Graph these energy levels in Joules, including n-5, in your lab...
!. Why does it make sense that tRNA and rRNA molecules are more stable than mRNA molecules? 2. What is meant by the genetic code being universal and redundant?
Could anyone explain why the first compound is more stable than the one I circled? And also, why is resonance a stronger influence and not induction? Thanks! 15. Circle one of the following charged compounds which is most stable. (3 Points) Which is the stronger influence for your choice? a) Resonance or b) Induction (hyperconjugation)? (2 Points)
