What intermolecular forces are present between two molecules of SeF₄? What intermolecular forces are present between two molecules of SeF₆?     Which one of the following explanations best describes why the boiling point of SeF₄ is higher than the boiling point of SeF₆?   A) The dispersion forces for SeF₆ are much stronger than those of SeF₄ because SeF₆ is a larger molecule.

States of Matter

The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates). 

Chemical Reactions and Equations

When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
