why does calcium carbide = Ca2C
I thought ca has a 2+ charge which would go to the C and would be CaCl2
Can someone explain when those superscripts transfer, is it betweeen non metals , or just metals

Ca does have a 2+ charge.
C has a 4+ or 4- charge.
and Cl has a 1- charge.
It has nothing to do with whether or not they are metals.

Calcium carbide is CaC2. It has the structure Ca++ (-)C*triplebond*C(-). If you add water to it, you get acetylene gas:
(-)C*triplebond*C(-) + 2H2O ===> HC*triplebondCH (acetylene) + 2OH-
