Learners assign oxidation numbers to atoms in neutral compounds and in polyatomic ions. Six examples are worked through in detail, and three problems are provided.
Common Types of Oxidation-Reduction Reactions
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners identify combination, decomposition, displacement, and combustion types of redox reactions. They also watch a video clip that demonstrates the reaction of sodium and water.
Dilution of Hydrochloric Acid
By Jill Larson
In this interactive object, learners examine how to properly dilute hydrochloric acid.
The Structure of an Atom
Students examine atomic structure and the octet rule.
By Dr. Miriam Douglass, Dr. Martin McClinton
Learners view several movie clips that demonstrate the use of an indicator to follow the neutralization reaction that occurs when an acid and a base are mixed. Students test their knowledge in a series of questions. Immediate feedback is given.
By Kaye Krueger
The learner reads an explanation of all of the elements that comprise a future-state map. A map is shown.
Logic State Signals
By Terry Bartelt
In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.
Logic State Indicators
Instructions on how to interpret state indicator symbols for input and output terminals of digital devices is presented.
Students observe the operation of a tri-state buffer used in digital electronics. A brief quiz completes the activity.
Thank you for this wonderful lesson. Textbooks dont do justice to mathematical processes such as this, because they are not static processes. Please make more of these.
