Question

When the metallic element sodium combines with the nonmetallic element bromine, br2(l), how can you determine the chemical formula of the product? how do you know whether the product is a solid, liquid, or gas at room temperature?

Answer 1

The answer is

1)The chemical formula of the product is NaBr

2) The product is a solid

The explanation:

The ions of the two reactants are Na{+} and Br{-}, so the formula of the product is NaBr.

and when the NaCl is a solid a room temperature. and when NaBr has similar properties to NaCl, so NaBr is a solid at room temperature too.

so our chemical formula for the product is NaBr and It's a solid at room temperature.

2 Na + Br2 → 2 NaBr
