- Using the program Stoic
-
- Learning about stoichiometry can be very difficult for the
- introductory chemistry student. This program is designed to be
- a non-threatening device which can provide the student with
- practice in both balancing chemical equations and solving
- stoichiometry problems. Students using the program in a
- computer lab will be presented with the reactions in a different
- order.
-
-
- Installing stoic on you hard drive.
- To install stoic on your hard drive type and enter the word
- install at the dos prompt when you are in the directory where the
- bondit files are contained. A directory called c:\stoic will be
- created and all files will be transferred to that directory. As
- an alternative use the dos copy command to copy all files to a
- directory of your choice.
- To show the stoic icon on Program Manager in Windows select
- the program group you want to contain the icon. Select New from
- the File menu of Program Manager. Program item should be chosen.
- The name of the program is Stoichiometry and the command line is
- c:\stoic\stoic.exe. Double click on the icon to start the
- program.
-
-
- Advantages of registering:
- When you register (see register.doc) you will receive 13 more
- reactions for the balancing portion of the lab and 14 more reactions
- for the stoichiometry section. Registration costs $10 + $2 shipping
- and handling. This fee entitles you to a site license for the
- program and a copy of a lab which can be used with the program
- will be included.

- Using Stoic:
-
- Balancing Chemical Equations:
- The purpose of this portion of the program is to provide
- the chemistry student with practice in balancing chemical equations.
- All major type of reactions will be presented. The unregistered
- version of the program will present only 2 reactions, the registered
- version contains 15 different reactions to balance of all types.
- To start this portion of the program select Balancing Chemical
- Equations from the Stoichiometry menu or press the F2 key. An
- equation will appear in the main window. To balance the equation
- type the number of the coefficient (the number in front of the
- formula) for each substance in the equation. To move from
- substance to substance use the TAB key. Make sure the number
- of atoms of each element is the same on both sides of the arrow.
- When you believe you have balanced the equation correctly press
- the enter key. You will be informed if you are correct or
- incorrect. When all of the equations have been balanced you
- will be informed.

-
- Stoichiometry Problems:
- The purpose of this portion of the program is to provide
- the chemistry student with practice in solving various
- stoichiometry problems. Mass-mass, mass-volume,and volume-volume
- problems are included. To start this portion of the program select
- Stoichiometry Problems from the Stoichiometry menu or press the F3 key.
- A balanced chemical reaction will appear along with a grid below
- the reaction with entries for mass, moles, and volume(if appropriate).
- The goal is to fill in every space in the grid by solving for mass,
- moles, or volume. The first thing that must be done is a starting
- value must be place into the grid. To do so click on New Mass,
- New Moles,New Volume, or Random Value. If you choose new mass,
- moles, or volume a dialog box will appear asking you for the value
- you want to input. Enter the value and then click on OK or press
- enter. You then need to place the value on the grid by choosing
- the substance you want to assign the value to. To do so click the
- left mouse button on the formula of the substance in the chemical
- equation. The value will appear in the appropriate place on the
- grid.
- The next step is to choose the starting and ending quantities
- for your problem. Click the left mouse button on the starting
- quantity (which is the only value present on the grid if you have
- just started) and then the right mouse button on the area of the
- grid you want to solve for. A series of conversion factors will
- appear below the grid. Click on each conversion factor as you
- would use it in the correct order to solve for the desired quantity.
- If the conversion factor is correct it will appear at the bottom
- of the window next to the starting quantity. If incorrect you will
- be informed. When you have chosen the correct conversion factors
- to solve for the desired quantity a dialog box will appear asking
- you to find the answer. Using a calculator calculate the answer
- to 3 significant figures and enter into the dialog box. If correct
- you will be notified.
- Fill in the remander of the grid by choosing quantities
- present on the grid and solving for quantities not determined yet.
- When the grid is completed you will be informed and a new problem
- will be given. The unregistered version only has one problem whereas
- the registered version has 14.
- Help is available at any time during the program by choosing
- Index from the Help menu. If you do not know how to use Windows
- Help choose Using Help from the Help menu.
