Assigning Oxidation Numbers and Balancing Half-Reactions
Detailed graphics explain oxidation numbers within molecules and complex ions. Examples show the rules for assigning oxidation numbers and for writing half-reactions using oxidation numbers.
-
Balancing Oxidation-Reduction Reactions Using Oxidation Numbers
Generates oxidation and reduction half-reactions using oxidation numbers and rules from the previous program. Electrons are balanced and the two half-reactions added to obtain the balanced overall reaction.
-
Introduction to Voltaic Cells
Explains how electrical energy is harnessed from redox reactions. Studies simple voltaic cells and explains their function. Discusses commercial cells in terms of their usefulness and limitations, electrochemical corrosion and cathodic protection.
-
Voltage and Voltaic Cells
Discusses reasons for a standard half-cell potential and explains the electric potentials on the reduction half-reaction table. This table is used to predict net voltages from redox reactions, and if the reaction is spontaneous or non-spontaneous.
-
Succession and Climax Communities
Examines successional events and their causes in various communities and ecosystems. Analyses data on population and community change and examines the impact of human activity on various ecosystems. Presents some new ideas on the concept of succession.
-
Patterns of Population Growth and Management
Explores patterns of population growth and population management strategies. Illustrates the J-shaped growth curve of r-selected populations and the S-shaped growth curve for K-selected populations. Discusses biodiversity and sustainable development.
-
Population Changes, Density and Chaos
Demonstrates how mathematical formulas can be used to analyse population changes. Explains population growth cycles and outlines the factors that affect density. Introduces the chaos theory and how it is used to study population changes.
