When the valency of calcium is 2 plus and the valency of carbide is 4- how does calcium carbide get the formula CaC2?

CaO + 3C >> CaC2 + CO
This reaction can not be produced at a normal temperature achieved by combustion, but in an electric arc furnace. I can find out no more than that.
Added:because the 'valency' of carbide is NOT uniqely -4:Actually in metal salts it's ion is (C2)2- , so with Ca2+ it forms CaC2
The structural formule is not C-Ca-C but -Ca-(C=C)- formed in a chain with a triple bond between the Carbon atoms: ..... -Ca-C---C-Ca-C---C-Ca-..... etc.
Even in ethyn H2C2 it is considered to have a -2 valency, though this is not a ionic (metal) salt.

What is the valency of carbide?
The valency of Carbide is -4. Yet for some unknown/unexplained reasons Calcium Carbide is CaC2 and not Ca2C.

What is the chemical formula for calcium carbon?
CaCO3CaCO3-----Ca+2-calciumCO3-2--carbonate
What is the compound name for Cal2?
CaC2 is Calcium Carbide. Ca2C does not exist.
What is the name of the chemical formula Ca2C?
There is no Ca2C. The formula of calcium carbide is CaC2. That's because the Ca has a 2+ charge the then the two carbons bond via a triple bond, leaving a 2- charge.[:C triple bond C:]^2- Ca^2+

What is the skeleton equation for calcium carbide plus oxygen euqals calcium plus carbon dioxide?
CaC2+O2------> Ca+ CO2
Why Formula of calcium carbide is CaC2?
The oxidation value (number) of C atom in carbide (not corbide) is -1, and of Ca always +2. This makes one Ca reacting with two C atoms in forming CaC2.Calcium Carbide is a common but improper name for CaC2.It's proper name is Calcium Acetylide.In Calcium Acetylide there are three covalent bonds joining the Carbon atoms, andthe forth bond of each Carbon go to Calcium forming an ionic bond.Crystal structure :The common crystalline form at room temperature is tetragonal, a distorted rock salt structure with the C22− units lying parallel.(Cf. 'Related links' for ionic picture)
