What is the difference between Addition and Condensationreactions? How does this relate to polymers?
Write a balanced nuclear equation for the following:
When iridium-192 emits a beta particle as it decays
Compare and contrast the molecular structure and performancecharacteristics of LDPE and HDPE. Provide an example of each typeof polymer
Describe two types of methods that can be used to mold plasticproducts.
Tin (Sn), with a mass number of 126 and an atomic number of 50,decays by beta emission. Identify the product of the nuclearreaction by providing its atomic symbol (2 points), mass number (2points), and atomic number (1 point).
Uranium (U) has a mass number of 238 and an atomic number of 92and decays by emission of an alpha particle. The product of thisdecay is (Points : 5) Â Â Â Â Â Â uranium(U), with a mass number of 234 and an atomic number of 92.
      lead (Pb), with a mass numberof 234 and an atomic number of 91.
      thorium (Th), with a massnumber of 234 and an atomic number of 90.
      radium (Ra), with a massnumber of 234 and an atomic number of 88.
      thorium (Th), with a massnumber of 234 and an atomic number of 91.
