${\boxed{\boxed{\fcolorbox{black}{red}{Your\:Answer}}}}$

$<p style="color:cyan; font-family:cursive;background:black;</p><p>font size:25px;"> There is a rule in chemistry called the “like dissolves like” rule which says that polar substances can be dissolved in a polar solvent and a non-polar substance can dissolve in a non-polar solvent. ... So water and oil do not mix because of a difference in polarity and therefore it is a heterogeneous mixture.$
