Would you expect the crystal on the right to be more or less stable enthalpically (AH)? A. Less stable B. More stable C. Equal AH Ostwald ripening Nature Materials 1.205 - 206 (2002) At equilibrium, why would small crystals get smaller and bigger crystals get bigger? (Grey and Green are the same molecules, just from different crystals) A. The molecules at the periphery have less enthalpic stabilization. Ostwald ripening maximizes enthalpic stabilization B. The molecules at the periphery of the...
How do you do this? Under what pH condition water is relatively more stable? Use E0 O2/H2O = 1.34 V and pO2 = 1 atm. A) At pH 10 B) At pH 12 C) Water is stable irrespective of pH
Cyclopropane is more reactive than most cycloalkanes. What factors lead to cyclopropane being less stable than other cycloalkanes? a. Angle strain b. Torsional strain c. Torsional strain, angle strain and steric strain d. Steric strain e. Torsional strain and angle strain of. Torsional strain and steric strain g. Angle strain and steric strain
Do you think that there is more or less communication between people than there was before life revolved around technology? Is it helpful that things are so automated or does it hinder progress? Think about it--do you feel more focused or less focused in school than you did ten years ago? Is it because of technology? Is it because society's acceptable means of communication have evolved? Is it better or worse?
Do you think bacteriophages are likely to be more or less diverse than prokaryotes? Than eukaryotes? Why? Is a plaque the result of the lytic or lysogenic pathway of the phage lifecycle? Explain. Why were you instructed to make three dilutions of the phage in this experiment? What purpose does this serve the experiment?
please answer all parts, thanks! 1. More substituted alkenes are more stable than less substituted alkenes. Show the orbital overlap that helps to explain this observation. 2. Why is the heat of hydrogenation for an alkene exothermic? Analyze the bonds that are changing. AH = -30 kcal/mol Explain: + H2 3. Treating alkene "A" below with HBr can lead to a number of products. "A" SM + H-Br A bunch of products. For real, hella products. 3.A. Label the stereocenters...
Do you believe ethics in the workplace are more or less important today than in the past. Why?
!. 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?
Recall that Zaitsev’s rule says that more substituted alkenes are more stable. Therefore, propene is less stable than trans-but-2-ene, which is less stable than 2-methylbut-2- ene, which is less stable than 2,3-dimethylbut-2-ene. In Chapter 7, we showed that we could demonstrate this stability ordering by using heats of hydrogenation. a) Does the same apply for other groups, besides alkyl groups? For example, compare the stability of propene, trans-but-2-ene and trans-1-chloroprop-1-ene to compare the effects of adding a chlorine instead of...
