Can they be separated? - CORRECT ANSWER A homogeneous mixture is a uniform composition throughout whereas a heterogeneous mixture has other substances. They can be separated but through physical processes. What is the difference between a physical and chemical property? Physical vs chemical change? - CORRECT ANSWER A physical prope...

Blackbody - ANSWER-In object that absorbs 100% of the radiation that hits it. Therefore it reflects no radiation and appears perfectly black (absence of light) Blackbody radiation - ANSWER-When I blackbody emits specific amounts of energy thought to be produced by standing waves What does classical physics tell us - ANSWER-The amount of radiation the middle of each frequency should be proportional to the number of waves present Quantum - ANSWER-A small bundle of energy that acts like an...

4.1: ATOMIC STRUCTURE Earlier in this course, we explored a very elementary view of atomic structure. We learned about protons, neutrons, and electrons (the three elementary particles that comprise an atom) and their properties. In this module, we will study these particles in detail and learn how their presence and arrangement determines the properties of all matter. The Electron During the 1800s, a number of scientists, including Sir Humphrey Davy, Michael Faraday, R. A. Milligan, G. J...

symbol for wavelength - ANSWER-λ symbol for frequency - ANSWER-v energy increases as frequency _____ and wavelength _____ - ANSWER-increases, decreases when waves interact and the crests and waves reinforce each other - ANSWER-constructive interference when waves interact and create bands of light and dark - ANSWER-destructive interference what experiment proved the existence of waves? - ANSWER-double slit experiment when a high intensity light is shined on a metal, electrons are emitted ...

Why is electronic structure important? - Answer All of chem is governed by transfer of electrons or the arrangement of electrons. How do you study electronic structure? - Answer Use interaction of light with matter to study the electronic structure. Light - Answer a "wave of energy" that consists of oscillating electric and magnetic fields. Frequency - Answer number of complete cycles pf electric fields that pass a given point per second. Wavelength - Answer distance between successive ...
