Answer:
It Is A Non-polar Liquid
Explanation:
When two liquids are mixed, two things are possible;
i) the both liquids may form one phase
ii) the both liquids may separate into two distinct phases
Two liquids of the same type will form a single phase when they are mixed. Two liquids of different types ( e.g a polar and a non polar liquid) will separate into two distinct phases when they are mixed.
Hence, when an unknown liquid is added to water and the liquid floats on top of water as a separate layer, then the liquid is a nonpolar liquid because we know water as a polar liquid.
