Can a dislocation with the burgers vector given dissociate into
partial dislocations per reaction i? how about reaction ii? Explain
how you know. What crystal structure is the dislocation found in in
case i? How about case ii? What family of planes would the
dislocation be slipping on in case i? In case ii? If both i and ii
are edge dislocations suggest a plausible line vector for each
dislocation.
i) (ao/2)[10-1] (ao/6)[2-1-1] + (ao/6)[11-2]
ii) (ao/2)[-101] (ao/6)[-2-11] + (ao/6)[-1-12]

Question 4: Write down all of the slip planes and slip directions for simple cubic (SC). How many slip systems are there? Question 5: The Burgers vector b indicates the direction and magnitude of dislocation slip in crystal structures. Said simply, the Burgers vector closes the loop when traversing an equal number of steps around a dislocation. Using a figure like shown here, graphically draw the Burgers vector around a dislocation defect in a simple cubic crystal. Question 6: Permanent...

if a reaction is Oxidation reduction or not. Thanks a lot
OXIDATION-REDUCTION Introduction Chemists refer to reactions which involve a transfer of electrons from one reactant to another as oxidation reduction reactions of just "redox" reactions. Oxidation is defined as a loss of electron and reduction as a gain of electron by a substance during a chemical reaction. The loss of electrons by one substance...
