What is PV=nRT?
Coulomb's Law
1. The greater the charge the greater the attraction
2. The greater the distance the smaller the attraction

Positive
Potassium Chloride
What is KCl?
What is 11?
A sealed container holds chlorine trifluoride gas (ClF₃) at a pressure of 403.3 kPa and a temperature of 514 K. The container is then heated until the temperature reaches 760 K, while the volume remains constant.
What is the new pressure (in kilopascals) of the ClF₃ gas after heating?
What is 600 kPa?
What trend increases from left to right and bottom to top across the periodic table?

Second Law of Thermodynamics
What is the entropy of an isolated system always increases or remains constant in any natural process?
Why does atomic radius increase down a group even though nuclear charge increases?
What is due to more electron shells and increased shielding?
How many electrons can fit in a 3d subshell?

H2SO4
What is sulfuric acid?
What is the definition of a mol? (Verbal definition and how many particles/atoms is in one mol?) Bonus points if you can say who came up with that number
What is a unit of measurement in Chemistry and 6.02*1023 particles? Bonus point: Avogadro
Name at least 3 of 5 Kinetic Molecular Theory statements.
What is
Gases have very large numbers of tiny particles that are far apart from one another compared to their size.
Gas particles are in constant rapid motion in random directions.
Collisions between gas particles and between particles and the container walls are elastic collisions.
There are no forces of attraction or repulsion between gas particles.
The average kinetic energy of gas particles is dependent upon the temperature of the gas.
Explain why fluorine has the highest electronegativity.
What is due to its small size, high nuclear charge, and needing only one electron to fill its octet?
Why does chromium have an exception in its electron configuration?
What is half-filled d-orbitals are more stable?
The difference between polar covalent and nonpolar covalent bonds
What is equal or unequal share of electrons?
A 12.0 g piece of metal at 100.0°C is placed into 100.0 g of water at 25.0°C. The final temp is 27.0°C. Assuming no heat loss and c of water is 4.18 J/g°C, calculate the specific heat of the metal.
