Use the method of half-reaction to complete and balance the following redox reaction, and determine how many moles of electrons are transferred according to the balanced reaction. ClO−4+NO2(g)⟶Cl2(g)+NO−3(aq)

Substance a is a nonpolar liquid and has only dispersion forces among its constituent particles. substance b is also a nonpolar liquid and has about the same magnitude of dispersion forces among its constituent particles. when substance a and b are combined, they spontaneously mix.
