3. Which oxidation-reduction reactions are best balanced by the half-reaction method? (1 point)
covalent reactions
acid-base reactions
ionic reactions
intermolecular reactions

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

Ithink its solid. hope this

It's called the falling actionwrong subject by the way
