When the metallic element sodium combines with the nonmetallic element bromine (Br2), is the product a solid, liquid, or gas at room temperature? I will give brainliest if you can explain how one would know this information.

it is a solid at room temperature.

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.

answer

the ions in solute supperate from eachouthere

the answer is minerals.
