Stoichiometry Exercises of the Elements, Formulas and Reactions |
|
This Windows App generates the visualization of an unrestricted sequence of ten types of stoichiometric problems which, even those of the same type, are always different from each other.
Every problem requires a numerical answer by the keyboard or keyboard on the screen.
The App for each answer displays:
1) The given answer
2) The result calculated by the App
3) The percentage error
4) The correctness or incorrectness of the given answer within the limits of the allowed error
5) The number of correct answers
6) The number of wrong answers
7) The number of total answers
8) The evaluation in tenths, thirtieths or cents
The App also displays a periodic table which shows, when the caret is on the symbol of an element, the atomic weight (IUPAC 2009), the atomic mass and the molar mass of the element.
It is possible to activate and display a countdown timer which interrupts the App after a chosen time.
If the App is not interrupted by the timer or by the operator, it continues indefinitely to propose always different problems.
The App can be driven by keyboard, mouse, touchpad and touchscreen similarly to Windows Notepad or Windows Word.
The App is free for students and teachers of all schools. They can notify chmsoft of any errors they have found in the App by means of chmsoft postmaster. Thank you.
