Concept explainers
(a)
Interpretation:
The reason behind the fact that why CFC are phased out as refrigerators, aerosol sprays, foams and medical inhalers has to be identified.
Concept Introduction:
Monomer: A molecule is considered as monomer when this molecule bonds with another identical molecule which results to form polymer.
(b)
Interpretation:
The way how the given property of CFC is linked with their phased out fact has to be identified.
Concept Introduction:
Polymers: Monomers combine together to form polymers. Monomers are the repeating units of small molecules which link together to form polymers and the process is called as polymerization. Polymers are macromolecules which are formed a by number of repeating units called monomers.
Monomer: A molecule is considered as monomer when this molecule bonds with another identical molecule which results to form polymer.
(c)
Interpretation:
The properties shared among HDPE, LDPE, PVC and PS with CFC has to be named.
Concept Introduction:
Polymers: Monomers combine together to form polymers. Monomers are the repeating units of small molecules which link together to form polymers and the process is called as polymerization. Polymers are macromolecules which are formed a by number of repeating units called monomers.
Monomer: A molecule is considered as monomer when this molecule bonds with another identical molecule which results to form polymer.
(d)
Interpretation:
The reasons that unlike CFC it is highly unlikely that plastics will be phased out has to be identified.

- The reaction of what nucleophile and substrate is represented by the following transition state? CH3 CH3O -Br อ δ CH3 Methanol with 2-bromopropane Methanol with 1-bromopropane Methoxide with 1-bromopropane Methoxide with 2-bromopropanearrow_forwardWhat is the stepwise mechanism for this reaction?arrow_forward32. Consider a two-state system in which the low energy level is 300 J mol 1 and the higher energy level is 800 J mol 1, and the temperature is 300 K. Find the population of each level. Hint: Pay attention to your units. A. What is the partition function for this system? B. What are the populations of each level? Now instead, consider a system with energy levels of 0 J mol C. Now what is the partition function? D. And what are the populations of the two levels? E. Finally, repeat the second calculation at 500 K. and 500 J mol 1 at 300 K. F. What do you notice about the populations as you increase the temperature? At what temperature would you expect the states to have equal populations?arrow_forward
- 30. We will derive the forms of the molecular partition functions for atoms and molecules shortly in class, but the partition function that describes the translational and rotational motion of a homonuclear diatomic molecule is given by Itrans (V,T) = = 2πmkBT h² V grot (T) 4π²IKBT h² Where h is Planck's constant and I is molecular moment of inertia. The overall partition function is qmolec Qtrans qrot. Find the energy, enthalpy, entropy, and Helmholtz free energy for the translational and rotational modes of 1 mole of oxygen molecules and 1 mole of iodine molecules at 50 K and at 300 K and with a volume of 1 m³.
