Structure Tutorial
•
Section 13.1 Enthalpy
(p. 612-616)
Learn how to calculate how much energy is absorbed or released
by a reaction that takes place under conditions of constant
pressure. Includes practice exercises.
Section 13.1 Dissolution
of Ammonium Nitrate (p. 612-616)
Explore the intermolecular forces that contribute to the overall
Hsolution
of the dissolution of an ionic compound in water.
Section 13.2-13.3 Entropy
(p. 616-622)
This tutorial includes an "Entropy Battle" game which challenges
you to maintain order within a system as the temperature rises
and the phase level moves from solid to gas. Concludes with
practice exercises.
Section 13.2 Molecular
Motion (p. 616-621)
Use an interactive graph to explore the relationship between
kinetic energy and temperature. Includes practice exercises.
Section 13.4 Gibbs Free
Energy (p. 622-629)
Learn to calculate the maximum potential energy available
to do work in a system. An interactive "Gibbs free energy
calculator" allows you to manipulate variables entropy, enthalpy
and temperature to explore the effect on G
of a reaction. Includes practice exercises.
Section 13.5 Chiral Centers
(p. 630-645)
This tutorial reviews the rules for determining whether a
molecule is chiral, and explains how to distinguish between
the R or S orientations. A "Protein Pileup"
game challenges you to quickly orient chiral substrate molecules
so that they will bind to an stereoselective enzyme active
site. Includes practice problems.
Section 13.5 Chirality
(p. 630-645)
Use molecular visualization to explore the concept of chirality.
Rotate pairs of molecules to determine whether they can be
perfectly superimposed.
Section 13.8 Condensation
of Biological Polymers (p. 655-661)
This tutorial animates the condensation reactions for several
important biological polymers, and demonstrates that in each
case a molecule of water is released as the constituent subunits
of the polymer join.
