Reversible

When a system is reversible, does that mean that only change in total entropy is 0? How about change in internal energy?

When a system is reversible, it can be implied that the system is at equilibrium so yes the deltaS of the system would equal the negative deltaS of the surroundings.

Is delta U also 0

I believe if the process is isothermal, meaning there is no change in temperature, then the reversible system would have a delta U = 0.

As well as what Adrian said, a process can have delta U = 0 even with a temperature change if the system returns to its original state, since U is a state function.
