Chemical Transformations, a 5 CD Set, covers Chemical Reactions; Formulas,
Equations, and Stoichiometry; Chemical Equilibrium; Solubility; and Reaction
Rates.
Chemical
Reactions
Chemical Reactions
begins by reviewing compounds and solutions. Interactive lessons teach
students step-by-step how to balance equations. Five classifications of
chemical reactions are explained: combination, decomposition,
single-replacement, double-replacement, and combustion. Amazing video examples
of chemical reactions are given, reinforcing results found in standard lab
experiments. Students also learn to predict the outcome of reactions by using
the activity series and the solubility chart.
Formulas, Equations,
and Stoichiometry
Instead
of presenting stoichiometry as an isolated subject, Formulas, Equations, and
Stoichiometry reviews and reinforces fundamental topics before the student is
immersed in this subject. The review progresses into a descriptive discussion of
chemical equations. Once chemical equations are well understood, students are
taught the mathematics that chemists use to describe such equations. This
program incorporates common terms, compounds, and reactions with which most
students are already familiar in an effort to reduce the complexity of the
subject matter. Interesting analogies, real life examples, and captivating
artwork bring the subject to life!
Chemical
Equilibrium
Concrete analogies
and step-by-step examples help students understand chemical equilibrium. The
concept of dynamic equilibrium is clarified with interactive tutorials.
Students quickly learn to calculate and understand the meaning of equilibrium
constants and reaction quotients with engaging narrations and graphics.
Examples using Le Chatelier's principle allow students to predict how changes
in such factors as concentration, temperature, and pressure affect
equilibrium.
Solubility and Precipitation
Solubility
and Precipitation begins with a review of solution chemistry and takes
students through topics such as dissolution and precipitation of ionic
compounds, determining solubility product constant (Ksp) and ion
concentrations for reactions at equilibrium, and separating substances from
mixtures. Dynamic animations and interactive tutorials make these difficult
concepts easy for students to understand.
Reaction
Rates
Why
are some reactions
energetically favorable but very slow to happen? This question is answered in
the program Reaction Rates. The general concept of rate is introduced with
numerical examples and sets the stage for an understanding of reaction rates.
Factors that affect reaction rates, such as temperature and concentration, are
explained through the concepts of collision theory and activation energy. A
step-by-step approach teaches rate laws and is reinforced with interactive
lessons covering both rate constants and reaction order. The program also
covers reaction mechanisms, including the rate-determining step. Throughout
the program, videos and animations help students visualize what happens at the
particle level and illustrate the incisive analogies.
