Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.

NO, because if you add water, you will see the aqueous layer get larger. While the organic layer stays the same volume.

urr... wouldn't it be better to take a sample from each layer, and add to a small sample  of water, to see whether a separate layer forms?  :) because it's not easy to notice which phase changed in volume.

Thats why you keep on adding water until you notice one of the layers getting larger.
