If the universe would be changed into its mirror image, would anything work differently?

This is assuming the laws of physics stay the same. 

The answer can be about physics, chemistry or anything else.

The fancy name for this is "Parity (P) symmetry."

The weak force, which governs neutrinos and beta decay and things like that, violates p-symmetry, so if you flipped the universe things would be different.

This fits into the bigger scheme of CP-symmetry (charge and parity..switch particles with antiparticles as well as flipping them in a mirror) which is violated in some circumstances, and CPT (flip time as well), which is thought not to be violated.
