program designed to calculate formula masses. From the chemical formula of a
substance its formula mass is calculated and shown together with the
calculations.
Note: Needs Visual Basic 6.0 SP5: Run-TimeRedistribution Pack (VBRun60sp5.exe)from MicrosoftDownload Center. If you don't have already, install this first. |
| Buffers | The design and preparation of buffers for pH
control is fraught with many difficulties. For example, the pH of a buffer is
strongly affected by ionic strength and by temperature, yet we are sometimes
guilty of ignoring these effects and failing to make appropriate compensations.
This is a very nice Javascript powered webpage which calculates recipes for many
different buffers.

| EniG. Periodic Table | EniG. Periodic Table of Elements contains the
basic data about the element in five languages. It shows visually the change of
physical condition with the change of temperature. The calculating module from
the programme Chemistry Assistant has also been integrated in the Periodic
Table.

| Radiation decay | RADIATION DECAY provides radioactive decay
information for 497 radionuclides. Data provided include the half life,
radioactive daughter nuclides, decay chain series, probabilities per decay, and
Decay product energies for alphas, betas, positrons, electrons, X-rays, and
photons.The radionuclide can be selected from an Alphabetical list, or selected
from a Periodic Table. (285K)

| Atoms, Bonding and Structure
| Eight teaching units: Unit 1 - Elements,
Compounds and Mixtures; Unit 2 - Forming Compounds, Unit 3 - Atomic Structure,
Unit 4 - Chemical Bonds, Unit 5 - Ionic Bonding, Unit 6 - Covalent Bonding, Unit
7 - Structure of Materials, Unit 8 - Bond Energies. Frequent reference to the
online Periodic Tables. (515K)

| EniG. Chemistry
Assistant | EniG. Chemistry Assistant is an expression
calculator for fast calculation of molecular weight of compounds (the element
symbols can be written in lowercase letters). All of the calculations can be
saved and recalled again. The calculator also provides a list of common physical
constants and performs various conversions between English and metric units.
Comment: Excellent software.

| BK Periodic Library | An interactive Periodic Table of the Elements
for Windows. Uses element naming scheme approved by IUPAC in 1997

| MolarMas | Determines the molar mass and percent
composition from a formula. Can handle enormous molecules. Common
abbreviationsthat are recognized include Me (CH3), Et (C2H5), and amino acids
(eg. Gly). (121K)
| |
| Chempac3 | Program to find solvents which meet your
search parameters. Solvents can be searched by various experimental parameters.
Let's say you need a solvent which is miscible with water, has a boiling point
between 75-100 degrees Celsius and a melting point below 0 degrees Celsius. This
program would allow you to search by all of these parameters at once to get a
list of usable solvents. There are 13 searchable parameters including formula,
molecular weight, boiling point, melting point, dielectric constant, dipole
moment, viscosity, and heat of vaporization. (59K)
