Question

The migration of atoms from lattice site to lattice site is only possible if the following: There must be an empty adjacent site The atom must have sufficient energy to break bonds with its neighbor atoms There must be an empty adjacent site and the atom must have sufficient energy to break bonds with its neighbor atoms There must be an atomic sites and sufficient energy to create strong bonds between atoms. One of the following is not nonferrous alloys: Aluminum alloys Steel alloys Nickel alloys Titanium alloys Thermosetting plastic: Can recycle such as nylon Cannot recycle such as nylon Cannot recycle such as phenols Can recycle such as phenols In Saturated hydrocarbons: Each carbon bonded to three other atoms Each carbon bonded to other three carbons Each carbon bonded to two other atoms Each carbon bonded to four other atoms The Arrangement of Strength polymer chain as the following: Network Branched Cross-Linked Linear/Direction of increasing strength

Explanation / Answer

22. There must be an empty adjacent site and the atom must have sufficient energy to break bonds with its neighbour atoms

23. Steel alloys

24. Thermosetting plastics can recycle like phenols

25. In saturated hydrocarbons each carbon bonded to four other atoms

26. D i.e. Linear polymer chain would have highest strength

25.
