************************************************************* * * * Visual Periodic Table 89 v2.0 * * * ************************************************************* Release: 2000-05-27 Update: 2000-09-01 Author: Markus Kvist Program file name: vpt89 Features: --------- -Nice, informative graphical user interface -Information on: type, atomic mass, electronegativity, oxidation number, melt and boil temperatures and more info! -Supports search for atomic number, symbol and name or part of name -Molecule mass calculator -Three temperature scales -Powerful Chemistry Equation Solver -Source code in C included Installation: ------------- The program comes in two versions: Doors and Independent. The Doors version requires the DoorsOS kernel installed. It can be run from both TI Basic and DoorsOS. This version is 14579 bytes. The independent version is a bit experimental, because I have not tested it on different systems. If it works, it can only be run from TI Basic. Simply choose your version and copy it to the calculator, and thats it! Running the program: -------------------- To run, locate vpt89 in the var-link menu and start it. There will be a first time info dialog (open again with [F1]). Navigate the table using the arrow keys. Some info will show at the top of the window. When you find what you are looking for, press [ENTER] to view the extensive info dialog. The escape button will exit the program. * Temperature scale In the info window the temperature is shown in degrees Celsius as default. To change this, press [F2] from the base window. You can choose between Celsius, Kelvin and Farenheit using left and right arrowkeys. * Search To start a search, press [F3]. In the dialog you can type the atomic number, symbol or name or the first few (>2) letters of the name you are looking for. Press enter to search, or clear to restart typing in the dialog. If a match is found, it is displayed. Press enter again to view extra information. * Molecule mass calculator To start the molecule mass calculator, press [F4]. Type a molecule formula. Exact case is necessery. Parenthesis' are allowed, but not koefficients before molecules. After you press enter, the mass is calculated and shown. If you wish to save the result, press [Sto]. * Chemistry Equation Solver The equation solver is a powerful tool for balancing chemical formulas. To start the equation solver, press [F5]. You are asked to enter reagents (e.g. left side of equation). After that you enter the products (e.g. right side of equation). Example: Na+O2 [ENTER] Na2O [ENTER] If the formula computes, the result will be displayed with correct koefficients. The answer to the example will be: 4 Na + O2 -> 2 Na2O One level of parenthesis' are allowed. Example: Al(OH)3+H2SO4 -> Al2(SO4)3+H2O * Turn off feature If you don't want to see my program any longer you can turn the calculator off by pressing [2nd]+[ESC]. Known bugs: ----------- The Chemistry Equation Solver has been tested with 30 equations getting positive result. You can get a bad result if you make formulas that has several solutions. However, there might be some undocumented features (or BUGs) which you should inform me of. I reserve myself for any errors in the information or information processing. All information is taken directly from the book, but typing errors may still have occurred. If you find something to be incorrect or missing, please notify me so i can change it. Contact: -------- Please send me your questions, ideas or source improvements *e-mail: theraven@swipnet.se *ICQ: 13652495 I hope this neat little program can be useful for you! Markus Thanks: ------- Special thanks to Janne West for supplying "other info" about the elements, as well as for beta testing the program.
