In this animated object, learners examine the properties of the hydrogen bond and how the bond changes when hair is shampooed or styled.
In this interactive object, students examine a type of chemical bond known as the "hydrogen bond."
Learners read this review of chemical hair bonds after completing learning objects on the peptide, disulfide, salt, and hydrogen bonds. Students may e-mail their quiz answers to their instructor.
Students read about the process of hair growth beginning with the joining together of amino acids.
The definition of an isotope is illustrated using the three isotopes of carbon. The three isotopes of hydrogen are discussed as exceptions.
In this well-illustrated activity, learners examine the three types of intermolecular forces: dipole-dipole forces, London or Van der Waals forces, and the hydrogen bond. Two interactive questions are included.
In this animated object, learners view hydrogen and hydroxide ions in a solution. A brief quiz on the basic principles of the term pH completes the activity.
