# Calcium metal (Ca) can be produced by passing an electric current through molten calcium chloride (CaCl_2). Chlorine gas (Cl_2) is also formed. What is the balanced equation for this reaction?

$C a C {l}_{2} \left(l\right) + \Delta \rightarrow C a \left(l\right) + C {l}_{2} \left(g\right)$

#### Explanation:

Is charge balanced? Tick. Is mass balanced? Tick.

If either quantity was unbalanced, we could not accept the equation as a legitimate representation of reality. What does the $\Delta$ symbol represent? Is this a redox reaction?
