Compounds 1.0.3

Chemistry Lab Companion

Stoichiometry or "grams-to-moles" calculations can be some of the most tedious chemistry problems. Mistakes are easily made as you look up atomic information and type them in your calculator.

Compounds solves these problems with ease and clarity using the technology of the iPhone.

Touch a molecule to edit. Touch elements to type. Shake to mix. Compounds does one thing and does it well, with a little style.

Instructions:
1. Add molecules to the beaker by pressing the “+” button.
2. Touch a molecule to select it.
3. Rotate the iPhone to bring up the Periodic Table keyboard.
4. Type in the molecular formula.
5. Rotate the iPhone to dismiss the Period Table.
6. Enter any coefficients by pressing the "xA+yB+zC" button.
7. Shake! to solve.
8. Adjust the amount in grams of any compound and see the results immediately.

Features:

Solves "Grams of A, Moles of B" calculations for up to 3 compounds.
A custom "keyboard" of elements shaped in the Periodic Table. No more hitting the Shift Key!

Subscripts are displayed as subscripts, not numbers of equal font size.

Uses iPhone orientation to display and hide keyboard.

Visual representation of problem helps remove the confusion of units and multiple compounds.

Displays moles, grams, and molar weight for each compound

Adjust the amount of any compound and instantly see the results.

Compounds is not a periodic table. There are many great "Periodic Table" available for the iPhone and iPod touch. Compounds was not designed to replace them, it was created to complement them. If you are looking for an app to provide generic atomic information, consider one of those excellent apps, which are all great companions to Compounds.
