The figure above shows a liquid of diatomic bromine in equilibrium with its vapor. Compare the strength of intermolecular forces with that of intramolecular forces. Which takes more energy to break - intermolecular forces or a covalent bond? How do you know (aka what evidence have you seen to support this??? Hint a graph maybe?) When a substance like Brz vaporizes, what types of forces are broken - intermolecular or intramolecular. Explain your reasoning!

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.
