1. Introduction
Michael L. Betz and Jason P. Hupka wrote ChemBalance Wizard 16/32
for the 1997 ColoradoSchool of Mines Computer Science Field Session.
Dr. Dean W. Dickerhoof originally developed a similar program in
QBASIC, but he requested a more user friendly version in a Windows
format.
ChemBalance Wizard 16/32 calculates balanced chemical equations given
a set of possible reacting species. The user inputs the number of
species, type of reacting solution (either neutral, acidic, or basic),
and the various species. After entering the necessary information, the
program calculates the balanced equations (if one or more exist) for
the given set of species.
This program features the Microsoft Wizard format for user interaction.
This format presents the user with a step-by-step procedure for
calculating the balanced equation. Only the pertinent information
is displayed on the screen at any one time. This feature, along with
the speedy calculation of the balanced equation, makes this an ideal
program for chemistry students and teachers alike.
The Title Page presents an introduction to the program. From here,
the user may view information about the program by clicking on the
About button, or may start the balancing procedure by clicking on
Begin. At any time the user may exit the program by clicking on Quit.
2. Using the Program
Using ChemBalance Wizard is straightforward, but the following pages
will present an explanation of each step in balancing a chemical
equation.
2.1 Preliminary Setup of the Balancing
The properties of the species and their reaction solution are set on
the Preliminary Setup Page.
2.1.1 Selecting the Number of Compounds and Ions
The program will need to know the total number of species taking part
in the reaction. This number includes all reactants and all products.
The maximum number of species a user may enter is 10, and the minimum
is 2. The user may type in the number, or use the convenient up or
down arrows to increase or decrease the number. Note that this number
includes the two species that the program automatically adds when the
user selects an acidic or basic reaction solution. The default value
for the number of species is 2.
2.1.2 Setting the Reaction Solution
In this box, the user may select the type of reaction solution. The
program selects Neutral or Non-Aqueous as the default value, but the
user may select either Acidic or Basic. If the user selects Acidic,
the program automatically adds the H+ ion and H2O to the species list.
If the user selects Basic as the reaction solution, the program
automatically adds the OH- ion and H2O to the species list. Nothing is
added for a neutral solution.
2.1.3 Showing the Results Page
If the user would like to see the Species Analysis Results Page before
the program calculates a balanced equation, a check mark needs to be
placed in the box next to Show Species Analysis Results. The default
is no check mark.
2.1.4 Buttons
The Rules button allows the user to view the rules for entering
chemical species. The Back button will go back to the Title Page, and
the Next button moves to the Species Entry Page. The Quit button
allows the user to exit the program.
2.2 Entering the Species
After clicking Next on the Preliminary Setup Page the user can enter
the various species on this page. The program displays boxes equal to
the number of compounds and ions the user selected. Only one species
may be entered in each box.
ChemTip: The Enter key can be used after entering a species to move to
the next species box. After entering the final species, the Enter key
will automatically select the Next button.
After entering all of the species click Next to analyze the entered
species. If one or more of the species boxes turn red, hold the mouse
cursor over the box to display the problem with that particular
species. After making the proper corrections, click Next to re-analyze
the species. Repeat this procedure until no errors occur.
2.3 Species Analysis
On the Species Analysis page, the user may review the results of the
species analysis. The user may verify if the species were entered
correctly by looking at each species, the elements the program found
in each species, and the number of them. Also included on this page
are the element names and the molecular weight of the species (useful
for calculating the mass of reactants and products). The Species
Analysis Page can be accessed after entering the species by selecting
Show Species Analysis Results on the Preliminary Setup Page, or by
clicking on the Results button on the Balanced Equations Page.
2.4 Balanced Equations
On the Balanced Equations page the user may view the balanced
equation(s) if one or more exist. The program will inform the user
if no balanced equations exist for the given species. From here,
click on Restart to go back to the Preliminary Setup Page, or click on
Review to see the Species Analysis Page.
ChemTip: If more than one balanced equation exists, try entering the
species in a different order. Sometimes the program will find
alternate balanced equations!
