Chem 141 Exam 3 2025 Questions and
Answers
Differentiate between properties of atoms and larger macroscale materials.Explain
why is it that atoms don't have macroscopic properties like melting
point, boiling point, and color, while macroscopic materials do (and can
beidentified by them) - --CORRECT ANSWER--Properties of atoms are alot
diffrent on the microscopic scale then on the macroscopic scale with large
materials. So you cannot identify a large object based on test ou wuld use to
identify and microscopic object such as an atom.
Explain the force and energy changes that occur when two atoms approach each
other and form a bond. Explain why a third body (another atom or molecule) is
(almost always) needed to form a stable bond. - --CORRECT ANSWER--A third
atom will absorb some of the energy lowering the energy between the two atoms
allowing them to form a stable bond.
What determines whether a bond or interaction is stable? Explain how temperature
influences the stability of bonds and interactions. - --CORRECT ANSWER--What
determines if a bond or interaction is stable is if most shell of electrons is full. If
