    Test Your Knowledge On AP Chem!

    The AP test is coming up...you should ace this!

    1. How many protons does Xenon have?

      Correct! 
      Wrong! 

      54 Protons

      Xenon has an atomic number of 54, so it has 54 protons!

    2. Which element is the most electronegative on the periodic table?

      Correct! 
      Wrong! 

      Fluorine

      Fluorine is the most electronegative. It's a trend you better know this!

    3. Which has the higher ionization energy?

      Correct! 
      Wrong! 

      Lithium has the higher ionization energy

      Don't forget Coulomb's Law!! Potassium has a larger atomic radius than lithium, the attractions are weaker. Therefore, it takes less energy to remove an electron from the atom with weaker attractions. Lithium has a smaller atomic radius, with stronger attractions. Therefore, it takes more energy to remove an electron from an atom with stronger attractions.

    4. What is molarity?

      Correct! 
      Wrong! 

      Moles of solute/Liters of Solution

      Basic definition!! DO NOT FORGET!!!!

    5. Which Intermolecular
      force is the strongest?

      Correct! 
      Wrong! 

      Hydrogen Bonds

      London Dispersion Forces are the weakest of the Intermolecular Forces!! Everything has them!

    6. If the equilibrium constant is less than the Q value, which direction does the reaction shift?

      Correct! 
      Wrong! 

      To the left

      Basic rule, memorize it.

    7. Which pairing is correct?

      Correct! 
      Wrong! 

      Endothermic Reactions have a positive change in enthalpy, and exothermic reactions have a negative change in enthalpy.

      MEMORIZE!!!!!!!!!!

    8. What do you include in an equilibrium constant expression?

      Correct! 
      Wrong! 

      (aq)

      Only (aq) reactants and products are included in the equilibrium constant expression.

    9. What happens in an oxidation reaction?

      Correct! 
      Wrong! 

      Oxidation reactions lose electrons.

      LEO GER: Loss of electrons is oxidation and Gain of elections is reduction.

    10. How can you identify intermediates?

      Correct! 
      Wrong! 

      Intermediates are produced then used again.

      You will see them as products first then reactants. If you see something that starts off as a reactant and ends as a product, that is a catalyst.

    11. Easy One:
      How many valence electrons does Hydrogen have?

      Correct! 
      Wrong! 

      1

      BRU if you forgot this, why are you even taking this quiz.
