Okay chemistry time: Both Barium (Ba) and Sodium (Na) are either alkali or alkaline metals, so they won't react because their reactivity levels are too similar. Which means there WOULDNT be a product. On top of that, sodium is not even diatomic, and there would be no equal sign in a chemical reaction, only an arrow. It just doesnt make sense with or without banana. That is all.
