An Equation Library of over 200 equations, the Periodic
Table of Elements with 15 properties listed for each element, Stoichiometry, a Constants
Library, a short Reference Library.
Easy entry of values for variables (with units) using the
menu keys provided. Effortless solving and converting of units.
Menu can be displayed in a large or small font.
The Equations Library is divided into seven categories,
with each Henderson category containing several sub-topics. Select equations in a
sub-topic to solve.
The variables in each equation set have descriptions in
addition to names, and often an equation set will have a picture associated with it.
Stoichiometry calculations are easy for the chemical equation set up.
A specific equation can be selected to plot, and a multiple
plot function can be used to do analysis when one of the variables has been changed
incrementally. A multi-plot screen display example is shown here.
The graphical periodic table includes 15 properties for
each element. Elements are easily selected by using the cursor movement keys. When
selected, an element’s name, symbol, atomic number, and atomic weight are displayed.
The contents of this card were designed to
cover first course General

The complete periodic table is presented at your finger
tips; each element can be visited by using the four cursor movement keys B C D E .
Properties included for each element are: atomic number, mass number, atomic weight,
density, oxidation state, electron configuration, physical state, electronegativity,
atomic radii, first ionization potential, group and family, melting point, boiling point,
and covalent radii. Elements can be accessed by symbol or element number.
Use the species library (or add your own species) to build
a chemical reaction, and solve for reactants and products. Solve the classic chemical
algebra problems. Set up your chemical reaction and evaluate and study the limiting
Dissociation constant PKas of selected weak acids; names
and formulas of common anions; percent composition (by volume) of air at sea level; vapor
pressure of water at sea level at selected temperatures; water Kws vs. temperature for
selected temperatures; Van der Waals constants for selected sets of gases; colligative
properties such as normal boiling point, freezing point, ebullioscopic and cryoscopic
constant for common solvents; expansion and compressibility for common materials; PKsps -
product solubility constants at 25 ° C for common precipitates; and bond energy and
distance for common bonds.
29 constants useful to both students and professionals.
