Explanation / Answer

ANSWERS

1. If we put liquid A & Liquid C together in any vessel, & both have different densities, then they form an immiscible liquid. The immiscible liquid have a separation zone which divides the liquid A & C.The liquid having lighter density will float over denser one. In question, liquid's A density is 0.80g/ml where C's density is 1.10g/ml. So liquid A will on upper part of vessel & C in bottom part & there lies a separation zones between A & C.

2. Vinegar : Miscible Olive Oil : Immiscible , Melted Butter : Immiscible , Lemon Juice : Miscible , Chicken Broth: Immiscible , Soy Sauce : Immiscible White Grape Juice : Miscible
