1. Explain why the type of bond affects the volatility of a substance. [TI]
The type of bond affects the volatility of a substance because ionic compounds tend to have a higher melting point than covalent compounds. This is because ionic compounds form lattices, and for ions to separate from the lattice, it needs a lot of energy. However, covalent compounds form single molecules that interact by intermolecular forces which are weaker than the ionic forces. The more unstable a bond is, the easier it is to change state, and more volatile it will be since electrons are constantly moving.
2. Does the strength of the bonds within a molecule affect its melting point? Explain why. [TI]
The strength of the bonds within a molecule does affect its melting point because for ionic compounds, which have ions that are tightly stuck together, to break apart, it

Which elements are found in the covalent compounds you tested? What do they have in common?
The elements found in the covalent compounds were Carbon, Oxygen, and Hydrogen. All these three elements are non-metals, and can form bonds with other non-metals in different ways.
6. Explain the difference in conductivity of tap water and distilled water. If there wasn’t a noticeable difference, explain why.
The conductivity of tap water and distilled water were both generally low. Distilled water is an ineffective conductor of electricity because since it is purified water, it contains very little ions, and its molecules do not have free electrons to travel which is necessary to transfer current. There isn’t much of a difference between the conductivity of the tap water and distilled water because both tap water a distilled water go through many processes to ensure that it is detoxified and safe to drink/use, which means that it as well will contain many ions. Therefore, both distilled water and tap water display low electrical conductivity.
