Respuesta :
The element Sodium will
form a +1 cation, while the bromine a -1 anion. Since the anion bromine is
always a liquid, therefore its symbol is Br2(l). So, the chemical equation for
their reaction is:
2Na(s) + Br2(l) -> 2NaBr(aq)
Answer is: the chemical formula of the product is NaBr (sodium bromide).
Balanced chemical reaction: 2Na(s) + Br₂(l) → 2NaBr(s).
In this chemical reaction, sodium is oxidized from oxidation number 0 (metal) to oxidation number +1 (in NaBr) and bromine is reduced, from oxidation number 0 (bromine nonmetal) to oxidation number -1 (in NaBr).
