Answer:

I think this is the answer

Answer 2

1. Atoms are defined as “the basic building blocks of matter”. It is the smallest constituent unit of matter that posses the properties of the chemical element. ... Molecules consist of one or more atoms bound together by covalent (chemical) bonds.

2. Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the behaviors of these particles differ in the three phases. ... gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern.

3. Kerosene and glycerine both are not miscible in water.

hence kerosene and glycerine do not get mixed in water.
