ExamReview question #7

Aufbau Principle- Electrons occupy the orbitals of the lowest energy level first.
For example, the electrons in nitrogen start out in the 1s orbital then the 2s and then they occupy 2p. Aufbau's principle is the reason why the electrons must occupy the lowest energy level first.

Pauli Exclusion Principle- Atomic orbitals can have two electrons, and these two electrons must have a opposite spin.
An example of the Pauli Exclusion principle in nitrogen would be found in orbitals 1s and 2s. There are two electrons in each of these orbitals and one is moving clockwise while the other must be moving counter-clockwise because it would not be stable if bother were moving the same direction.

Hund's Rule- With orbitals of equal energy, one electron occupies each orbital until they all contain one electron.
For example, if you are doing the orbital diagram for nitrogen it would utilize Hund's rule because it does not completely fill the p-orbital.

Physical Properties

One physical property of vinegar is the sour odor that it contains.

Another physical property of vinegar is that it is a clear, water-like liquid.

According to sophisticatededge.com, the density of vinegar is 1.01 grams per mL. Density is an intensive property because it is always 1.01 grams per mL.

According to enzyme-facts.com the boiling point of vinegar is 213 degrees fahrenheit or 100.6 degrees celsius.

According to enzyme-facts.com the freezing point of vinegar is 2 degrees celsius or 28 degrees fahrenheit. 

Chemical Properties of Vinegar

The acid in the vinegar reacts with salt, leading to a cleaner penny.

Vinegar is combined with Drano, creating heat due to an exothermic reaction.

Chalk begins to dissolve when added to vinegar, due to its acidity.

Vinegar and milk create a precipitate when combined

Vinegar and baking soda combine and create a white foam that quickly rises and overflows the bowl.

Vinegar

For my At-home Experiment I chose to use vinegar.  I chose vinegar because it is very useful in regular life, and I was interested in what its value is for chemistry.
