Chapter 12: Problem 84

Indicate whether the following statement is true or false: For an addition polymerization, there are no by-products of the reaction (assuming \(100 \%\) yield).

Short Answer

Expert verified
The statement is \(True\). In an addition polymerization, monomers are directly bonded to each other without releasing any by-products, and as the reaction is assumed to have a 100% yield, no side reactions occur to generate any by-products.

Step by step solution

01

Defining Addition Polymerization

Addition polymerization, also known as chain-growth polymerization, is a type of polymerization in which monomers are added to the growing polymer chain one at a time, and no by-products are formed.
02

Addition polymerization mechanism

In an addition polymerization, the monomers contain a double bond (or sometimes a triple bond) that can be broken to create radicals or other reactive species in the presence of an initiator. These reactive species then add to the double bond of other monomers, thus initiating a chain reaction for the polymer formation.
03

Determining if there are any by-products

The key point of addition polymerization is that the monomers are directly bonded to each other without any molecules being released as by-products. If we have 100% yield, it means that all monomers react to form the polymer, and no other reaction occurs to generate any by-products.
04

Conclusion

Since addition polymerization is directly bonding the monomers, and it's assumed to be a 100% yield, which means that all the monomers form the polymer without any side reactions. Thus, there are no by-products formed during the reaction. Therefore, the statement is \(True\).

Indicate whether each statement is true or false: (a) Substitutional alloys tend to be more ductile than interstitial alloys. (b) Interstitial alloys tend to form between elements with similar ionic radii. (c) Nonmetallic elements are never found in alloys.

Which statement correctly describes a difference between graphene and graphite? (a) Graphene is a molecule but graphite is not. (b) Graphene is a single sheet of carbon atoms and graphite contains many, and larger, sheets of carbon atoms. (c) Graphene is an insulator but graphite is a metal. (d) Graphite is pure carbon but graphene is not. \((\mathbf{e})\) The carbons are $s p^{2}\( hybridized in graphene but \)s p^{3}$ hybridized in graphite.

An increase in temperature causes most metals to undergo thermal expansion, which means the volume of the metal increases upon heating. How does thermal expansion affect the unit cell length? What is the effect of an increase in temperature on the density of a metal?

Orange light-emitting diodes are made from GaAs and GaP solid solutions, \(\mathrm{GaP}_{x} \mathrm{As}_{1-x}\) (see Exercise 12.79). The original orange LEDs emitted light with a wavelength of \(590 \mathrm{nm}\). If we assume that the band gap varies linearly with composition between \(x=0\) and \(x=1\), estimate the composition (the value of \(x\) ) that is used in these LEDs.

What is the minimum number of atoms that could be contained in the unit cell of an element with a body-centered cubic lattice? $(\mathbf{a}) 1,(\mathbf{b}) 2,(\mathbf{c}) 3,(\mathbf{d}) 4,(\mathbf{e}) 5 .$
