ALCHEMY - FINAL EXAM
Self Evaluation Test
I hope you have reviewed all your Alchemy studies because this Final Exam is comprehensive - it covers material from all four Ancient Elements. If you do not feel comfortable about one or more of the Ancient Elements, it would be wise to study them again before taking this Final Exam. However, please be sure to take this Final Exam because you cannot get your Diploma without it!
Choose the best answer by selecting one of the buttons.
Your answers will be graded and each one will be scored Correct or Wrong. Once you have the score and the list of incorrect answers you can use your "Back Button" to return to your exam and correct your errors. This time, this second time, you can carefully read each response, learn from it and choose the right answer. Students receiving a perfect score will be awarded a Diploma and the Title of "Apprentice Alchemist".
OK - here we go - the Final Exam! I am sure you will do well.
Good luck and enjoy!
ALCHEMY 1 : The atomic mass of an atom is determined by the number of ...
protons.
neutrons.
protons and neutrons (combined).
electrons.
ALCHEMY 2 : __________________ represents the "average" mass of an element, taking into account all the element's isotopes and their relative abundance.
Relative atomic mass
Daltons
Isotopes
Nucleons
ALCHEMY 3 : Hund's rule says ...
no more than two electrons may occupy a single orbital (subshell) and if two electrons do occupy a single orbital, their spins will be opposite to each other.
the total enthalpy change (total energy released or absorbed) as the reactions move from reactants to products, is "path independent".
when more than one orbital is available for occupation (because they are of the same energy) electrons occupy separate orbitals and do so with the same (parallel) spin.
atoms with vastly different electronegativities will form ionic (electrovalent) bonds.
ALCHEMY 4 : An atom's size (shell) and shape (orbitals) are determined by its ...
nucleus.
outer most electron cloud.
radioactivity.
charge.
ALCHEMY 5 : The four levels (values) of quantum mechanics determine...
the atom’s mass.
electron distributions in shells, orbitals and their shapes, and spin.
spin of an electron.
All of the above.
ALCHEMY 6 : Very __________________ atoms are ready, willing and able to steal electrons from other atoms.
electronegative
covalent
metallic
large
ALCHEMY 7 : _______________ bonds are the electrostatic interaction produced by the molecules that have a hydrogen bonded to an electronegative atom (O, Cl, F, even N).
Polar
Hydrogen
Van der Waals
Hydrophobic
ALCHEMY 8 : By definition, gases behave by ....
not interacting with other elements.
having a definite volume and taking the shape of the container.
filling a container and escape through any hole they find.
taking up definite positions with respect to each other and form permanent weak bonds.
The Table below shows the electronegativities of the Typical Elements. Use it to answer the following question.
Here's a small Periodic Table of the Typical Elements to help you answer this question.
ALCHEMY 16 : In the unbalanced equation Cu + O2 ------> CuO, the copper (Cu) goes from a valency of __ to a valency of ___ so the copper is ________.
0, 0, unchanged.
+2, +2, unchanged.
0, +2, oxidized.
0, +2, reduced.
ALCHEMY 17 : In the unbalanced equation Cu + O2 ------> CuO, the oxygen (O) goes from a valency of __ to a valency of ___ so the oxygen is ________.
-2, -2, unchanged.
0, 0, unchanged.
0, -1, reduced.
0, -2, reduced.
ALCHEMY 18 : Balance this equation. Cu + O2 ------> CuO
Cu + O2 ------> CuO
2Cu + O2 ------> 2CuO
Cu + O2 ------> 2CuO
Cu + O2 ------> CuO2
ALCHEMY 19 : Le Chatelier's principle says that a change in temperature, pressure or concentration will ....
shift the equilibrium to a new equilibrium position.
cause a reaction to run faster or slower.
lower the transition state.
increase entropy.
ALCHEMY 20 : Which of these things below have the lowest entropy?
A ball of wax.
A crystal of salt.
A star.
You!
You can now submit your exam to Merlin for grading. If your answers were less than perfect you will receive a score and a list of Incorrect (and Correct) replies. Then you can use your "Back Button" to return to this page and correct your earlier errors. Once you have corrected all your earlier errors (by rechoosing a correct answer when you were told you are wrong), you will get a perfect score.
