For each of the following pairs of polymers state whether it is possible to determine whether one polymer is more likely to crystallize than the other and if it is possible, note which one is the more likely to crystallize. (a) Linear and atactic poly(vinyl chloride); linear and isotactic polypropylene
(b) Linear and syndiotactic polypropylene; crosslinked cis-polyisoprene
(c) Network phenol-formaldehyde; linear and isotactic polystyrene
(d) Block poly(acrylonitrile-isoprene) copolymer; graft poly(chloroprene-isobutylene) copolymer

According to rutherford's nuclear theory, most of the volume of an atom is , so the volume of a hydrogen atom cannot be mostly due to the proton.according to rutherford's nuclear theory, the core of an atom (nucleus) contains most of of an atom and is , so the majority of the mass of a fluorine atom cannot be due to its nine electrons.according to rutherford's nuclear theory, the number of negatively charged particles outside the nucleus the number of positively charged particles within the nucleus, so a nitrogen atom has 7 protons and 7 electrons, while a phosphorous atom cannot have 15 protons and 150 electrons.word bank: dense, empty space, more than, mass, particles, the same as, less than, positively charged, negatively charged
