Is Fe3+ more reactive than Fe2+, and how do you know?
also, can someone help me fill in the second half of this eqn: Na + Ca2+----> ???
thanks!!!

to find out which is more stable you have to write out the electronic configuration of Fe3+ and Fe2+ and see which is more stable a fully filled and half filled shells are more stable than partially filled shells or orbitals.
i don't think so that the reaction of Na with Ca2+ is possible but in theory a more reactive metal will replace a less reactive metal ion. therefore it will give you Ca and Na+

the calcium has a greater electronegativity so it should strip an electron from the sodium.
Balanced equation
2 Na + Ca^+2 --> 2 Na ^+1 + Ca
i belive that is correct

look up ionization energies of Fe +++ and compare with Fe++.
As to the second q; Na + Ca2 will not occur. No rxtn. (are you sure you wrote that q correctly??).
