# What is the formula for the result of the reaction of Ca + Cl ->?

$C a \left(s\right) + C {l}_{2} \left(g\right) \rightarrow C a C {l}_{2} \left(s\right)$
This is clearly a redox reaction. Chlorine gas oxidizes calcium metal, and is itself reduced to chloride ion. The salt, $C {a}^{2 +} C {l}_{2}^{-}$ is the redox product..........
