Two molecules, a and b, have very different physical properties. a and b do not mix. molecule a boils at 82 c and freezes at 0 c. molecule b boils at 38 c and freezes at -68 c. which molecule has the higher total intermolecular forces?

Molecule A

Explanation:

Molecules with the stronger intermolecular forces are pulled tightly together  to form solid at higher temperatures and that's why the freezing point is higher.

Also, molecules with the stronger intermolecular force have greater interaction between the molecules and thus on heating do not boil easily and have high boiling point also.

So, Molecule A has boiling point and melting point both greater than molecule A . So, it has the higher total intermolecular forces.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

b.

the accuracy of the data.
