Question

if two atoms of sodium (Na) combine with one molecule of chlorine (cI2), which of the following could be the product?

Answer 1

You say "which of the following," but how are we supposed to help if you don't show us the possible answers!? X)

If the reaction alone is sodium combined with chlorine, then this is a simple synthesis reaction.\[\huge 2\text{Na}+\text{Cl}_2 \rightarrow2\text{NaCl}\]
