A particle is defined as a small potion of matter. From its definition, then a single atom can be considered as an atom. This is because an atom is the smallest unit of matter. Also, a molecule can be considered as a particles since it is a small portion of a certain object.
Potassium Sulfate = K₂SO4
SO4 = negative 2, so you need 2 K+ ions to counteract it, hence K₂

Explanation:
All molecules possess the London dispersion forces. However London dispersion forces is the only kind of intermolecular interaction that exists in nonpolar substances.
So, the only kind of intermolecular interaction that exists in dimethyl ether is London dispersion forces.
As for ethyl alcohol, the molecule is polar due to the presence of polar O-H bond. In addition to London dispersion forces, dipole-dipole interactions and specifically hydrogen bonding also occurs between the molecules.
Because ethyl alcohol is polar, it is more soluble in water than dimethyl ether.
Answer:
no
Explanation:
Homogeneous means that the substance looks uniform throughout. This means that all of it looks the same (ex. juice or water). Because you can see the different parts of raisin bran cereal with milk it is not homogeneous, it is heterogeneous.
