Instructions for using Stoic.

Start Stoic.
When you click on Start Stoic. your computer will load a Java program which provides practice in doing problems involving stoichiometry. Stoichiometry deals with the quantitative relationships between reactants and products in a chemical reaction. The basic unit that measures chemical quantity is the mole which contains 6.02 x 1023 particles of a pure substance and is equal to the gram formula mass of the substance.

After the program has started a window will appear containing a reaction(in blue), a series of conversion factors(in blue), and a question concerning the quantitative relationship between two of the substances taking part in the reaction(in black at the top of the window). Click on the appropriate conversion factor and if you are correct it will appear on the bottom of the screen in purple. When all of the correct conversion factors have been selected to solve the problem you will be asked to place the answer in the input box on the bottom of the screen. Use the calculator to the right to determine the answer if needed. Type in your answer to 3 significant figures and then click on the OK button. If you are correct you will be notified, if incorrect you will be asked to try again. If correct click on Next Problem to obtain a different question. As you solve problems the chart will fill until completed. When this point is reached click on Next Reaction to start a new set of problems with a different reaction. When all of the reactions have been completed you will be informed. The program can be exited at any time by clicking on the Close(X) button in the upper right corner of the window or by selecting Quit from the Stoichiometry menu at the top of the screen.
