Chemistry word equations

[Sorry!]

1. The problem statement, all variables and given/known data
Ok I am absolutely terrible at chemistry and a friend asked me to help her with this and she has no one else so i figured I would come here.

Write the word equation and balanced equation:

Ca(s) + Na2(g) -> Ca3Na2(s)

3. The attempt at a solution

Would the word equation just be Calcium + Sodium -> Tricalcium disodium? what about the balanced equation?

6Ca + 2Na2 -> Ca3Na2(s)

I have a feeling i'm doing this completely wrong lol.

I'm not gonna touch the "word equation." I wonder whether the compound is really called Tricalcium disodium...sounds funny.

You have 6 calcium atoms on the left hand side and only 3 on the right hand side. How is that balanced?

Perhaps something like "n moles of solid calcium plus ... yields ... " ?

You sure it is not nitrogen instead of sodium?

Yeah it was nitrogen sorry.

Ca + O2 > CaO

would it be balanced by
2ca + O2 > 2CaO??

[Bohrok]

That balances it.
