Answer:

[tex]2Na + Ca^{2+} \rightarrow Ca + 2Na^+[/tex]

Explanation:

Hello!

In this case, since this a reaction in which the oxidation state of the metals is changing, we need to apply a redox method for which:

[tex]Na\rightarrow Na^++e^-\\\\Ca^{2+}\rightarrow Ca+2e^-\\\\\\2Na\rightarrow 2Na^++2e^-\\\\Ca^{2+}\rightarrow Ca+2e^-[/tex]

Thus, the result is:

[tex]2Na + Ca^{2+} \rightarrow Ca + 2Na^+[/tex]
