Which two statements about redox reactions are true? PLZ HELP ASAP A.) Electrons are transferred from one atom to another.
B.) Double replacement reactions are redox reactions.
C.) Acid base reactions are redox reactions.
D.) One type of atom is oxidized and another is reduced.

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
