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.
Mole Ratios in Chemical Equations
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners use the coefficients in a balanced equation to develop the mole ratios of reactants and products involved in the reaction. Five interactive examples illustrate the method, and students test their knowledge by working four problems.
By Jill Larson
In this animated and interactive object, learners follow two rules to write unit conversion fractions.
Biomolecules The Carbohydrates
By Barbara Liang
Learners read a brief introduction to monosaccharides, disaccharides, and polysaccharides. The processes for dehydration synthesis and hydrolysis are shown.
In this animated object, students are introduced to moles as a measurement.
Common Types of Oxidation-Reduction Reactions
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.
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.
