Chemistry Topics

3 Things I Need Help On:

- Stoichiometry - I need help on this because it is very complex and i do not yet fully understand it.

- Combined Gas Laws - I need help on these because i did not fully understand them when we learned it and have not been able to memorize all of them.

- Periodicity is regularly repeating patterns or trends in the chemical and physical properties of the elements arranged in the periodic table - I need help on this because this sounds familiar but i do not know what exactly it is.

3 Things I've Never Heard Of:

- Molar Heat of Fusion - I do not recall learning this but supposedly it is a property that describes the amount of energy needed to convert one mole of a substance between its solid and liquid states

- Petrochemicals contain hydrocarbons, including propane, butane, and octane - I don't think i have heard of this but it is part of organic chemistry which i do remember.

- Biochemistry - This sounds familiar but i do not think that i know what it is.
