Question 1

What is solubility

Answer 1

the amount of a solute that will dissolve in a given amount of solvent

Question 2

What is ionization energy

Answer 2

The energy it takes to remove an electron from an atom

Question 3

What is electronegativity

Answer 3

Electronegativity is An atoms ability to attract bonding pair electrons. The higher the force of attraction the more an atom can pull electrons towards itself and the higher the electronegativity

Question 4

What is atomic radius

Answer 4

Atomic radius is the distance from the nucleus to the valence electrons. The larger the atomic radius the farther the valence electrons are from the nucleus and the weaker the force of attraction

Question 5

What is electron affinity

Answer 5

Electron affinity is a measure of the energy need to add an electron to an atom in its gaseous state. The higher the force of attraction the more an electron will be pulled in and the more negative the electron affinity.

Question 6

My list of acronyms

Answer 6

BATGAS, CASAHANA, BAR, ATIDICITOUS, WASBA, Taking Cold Vegetable Pizzas Goes To VAN, How Could Santa Have Big Houses In the North Pole, CODSCH so many hoard donuts; don’t make cold dough; make donuts, See Some Clean Cool Ants

Question 7

Compare acids and bases

Answer 7

Acids and bases are both aqueous, conductive, and cause change in pH. Acids are sour and bases are bitter, acids are stingy and bases are slippery, acids turn phenolphthalein from blue to red and bases turn it red to blue

Question 8

IMFs

Answer 8

london dispersion is when electrons occupy positions that create temporary dipoles. They are weakest type of IMF and The attractions are formed by everything. The larger a molecule the more london dispersion it has. Dipole dipole attractions are attractions between the charged ends of polar molecules with the oppositely charged ends of other polar molecules. Hydrogen bonds are formed between hydrogen and C, F or O since the electronegativity difference is the highest. IMFs are weak compared to intramolecular forces.

Question 9

Relationship between temperature and solubility

Answer 9

Direct for solids and inversely for gases

Question 10

What gives smaller molecules a greater solubility in water

Answer 10

They can more easily fit into spaces between water molecules
