,QUESTIONS
Question 1
Which task complements “Subatomic particles (protons, neutrons, electrons)
and isotopes” when the shared objective is “Atomic Theory and Structure”?
A. Lewis structures, resonance structures, and formal charges
B. Interrelationships between chemistry, technology, and societal impact
C. Quantum mechanical model of the atom, quantum numbers, and atomic orbitals
D. Systems, surroundings, heat, work, and the First Law of Thermodynamics
Correct Answer: C
Full Explanation: Atomic Theory and Structure: Quantum mechanical model of the atom,
quantum numbers, and atomic orbitals. Atomic Theory and Structure: Subatomic particles
(protons, neutrons, electrons) and isotopes. A: This describes “Chemical Bonding and Molecular
Structure”, rather than the requested focus. B: This describes “Science, Technology, Society, and
Environment (STSE)”, rather than the requested focus. D: This describes “Thermochemistry and
Thermodynamics”, rather than the requested focus.
Question 2
Which pair stays within the focus of “Chemical Bonding and Molecular
Structure”, without switching to “Foundations of Science and the Scientific
Method”? The pair must contain two distinct concerns. One concern to retain is
“VSEPR theory, molecular geometry, and bond angles”.
A. VSEPR theory, molecular geometry, and bond angles; Scientific inquiry, hypothesis
generation, and experimental design
B. Scientific inquiry, hypothesis generation, and experimental design; Ionic bonding, covalent
bonding, and metallic bonding
C. Scientific inquiry, hypothesis generation, and experimental design; Scientific inquiry,
hypothesis generation, and experimental design
D. VSEPR theory, molecular geometry, and bond angles; Ionic bonding, covalent bonding, and
metallic bonding
Correct Answer: D
Full Explanation: Chemical Bonding and Molecular Structure: VSEPR theory, molecular geometry,
and bond angles. Chemical Bonding and Molecular Structure: Ionic bonding, covalent bonding, and
metallic bonding. Foundations of Science and the Scientific Method: Scientific inquiry, hypothesis
generation, and experimental design. A: This describes “Foundations of Science and the Scientific
Method”, rather than the requested focus. B: This describes “Foundations of Science and the
Scientific Method”, rather than the requested focus. C: This repeats a different focus rather than
covering two distinct concerns in the requested area.

Question 3
A review brings together “Quantum mechanical model of the atom, quantum
numbers, and atomic orbitals” and “Electron configurations, Pauli exclusion
principle, Aufbau principle, and Hund's rule”. What is their shared area?
A. History and Philosophy of Chemistry
B. Science, Technology, Society, and Environment (STSE)
C. Periodic trends
D. Atomic Theory and Structure
Correct Answer: D
Full Explanation: Atomic Theory and Structure: Quantum mechanical model of the atom,
quantum numbers, and atomic orbitals. Atomic Theory and Structure: Electron configurations, Pauli
exclusion principle, Aufbau principle, and Hund's rule. A: That focus concerns “Contributions of key
historical figures in chemistry”, not the activity being assigned. B: That focus concerns
“Environmental considerations, green chemistry principles, and waste management”, not the
activity being assigned. C: That focus concerns “atomic radius, ionic radius, ionization energy,
electronegativity, and electron affinity”, not the activity being assigned.
Question 4
Among these proposed associations for “Classification and States of Matter”,
“Science, Technology, Society, and Environment (STSE)”, “Thermochemistry
and Thermodynamics”, “Periodic Table and Periodicity”, which one is
consistent? Pay particular attention to the role of “Organization of the periodic
table by groups, periods, and blocks (s, p, d, f)”.
A. Periodic Table and Periodicity — Enthalpy changes (Delta H), endothermic and exothermic
processes, and standard heats of formation
B. Periodic Table and Periodicity — Organization of the periodic table by groups, periods, and
blocks (s, p, d, f)
C. Periodic Table and Periodicity — Environmental considerations, green chemistry principles,
and waste management
D. Periodic Table and Periodicity — Kinetic-molecular theory of gases and gas laws (Boyle's,
Charles's, Gay-Lussac's, Ideal Gas Law, Dalton's Law of Partial Pressures)
Correct Answer: B
Full Explanation: Periodic Table and Periodicity: Organization of the periodic table by groups,
periods, and blocks (s, p, d, f). A: This option instead describes the following different focus:
Thermochemistry and Thermodynamics: Enthalpy changes (Delta H), endothermic and exothermic
processes, and standard heats of formation. C: This option instead describes the following different
focus: Science, Technology, Society, and Environment (STSE): Environmental considerations, green
chemistry principles, and waste management. D: This option instead describes the following
different focus: Classification and States of Matter: Kinetic-molecular theory of gases and gas laws
(Boyle's, Charles's, Gay-Lussac's, Ideal Gas Law, Dalton's Law of Partial Pressures).

Question 5
A brief initially required “Naming inorganic and organic compounds using
IUPAC nomenclature rules” for “Chemical Nomenclature and Formulae”, but
now concerns “Types of Chemical Reactions”. Which task matches the revised
requirement?
A. Lewis structures, resonance structures, and formal charges
B. Use of safety protocols, laboratory equipment, and chemical hygiene practices
C. Oxidation-reduction (redox) reactions, oxidation states, and balancing redox equations
D. Naming inorganic and organic compounds using IUPAC nomenclature rules
Correct Answer: C
Full Explanation: Types of Chemical Reactions: Oxidation-reduction (redox) reactions, oxidation
states, and balancing redox equations. Chemical Nomenclature and Formulae: Naming inorganic
and organic compounds using IUPAC nomenclature rules. A: This describes “Chemical Bonding and
Molecular Structure”, rather than the requested focus. B: This describes “Foundations of Science
and the Scientific Method”, rather than the requested focus. D: This describes “Chemical
Nomenclature and Formulae”, rather than the requested focus.
Question 6
A task handover separates “Contributions of key historical figures in
chemistry” from “Empirical and molecular formula determination from
percentage composition and molar mass”. Which first/second assignment is
appropriate?
A. First: History and Philosophy of Chemistry; second: Chemical Nomenclature and Formulae
B. First: Chemical Nomenclature and Formulae; second: History and Philosophy of Chemistry
C. First: History and Philosophy of Chemistry; second: History and Philosophy of Chemistry
D. First: Chemical Nomenclature and Formulae; second: Chemical Nomenclature and Formulae
Correct Answer: A
Full Explanation: History and Philosophy of Chemistry: Contributions of key historical figures in
chemistry. Chemical Nomenclature and Formulae: Empirical and molecular formula determination
from percentage composition and molar mass. B: The two roles are reversed: the first assignment
belongs with the second focus, and vice versa. C: Repeating the first assignment leaves the second
requirement without its own matching focus. D: Repeating the second assignment does not
address the first requirement.
