Stoichiometry

Java project that balances reactions and computes grams/moles.

Main Features

• Reading chemical compounds (e.g. C3H5(NO3)3(s)) from a string: src/stoichiometry/Compound.java
• Reading expressions (e.g. H2+O2) from a string: src/stoichiometry/Expression.java
• Reading chemical reactions (e.g. Al + I2 -> AlI3) from a string: src/stoichiometry/Reaction.java
• Balancing chemical reactions: src/stoichiometry/Reaction.java
• Setting the grams or moles of any compound to compute the other compounds grams/moles: src/stoichiometry/Reaction.java

Support Features

• Fractions and fractional operations: src/numbers/Fraction.java
• Solving systems of equations with fractional coefficients: src/numbers/Solver.java
• Python program to extract data about the elements from text files: elements/compile_data.py
• Enum of all the elements with symbol, full name, atomic number, and atomic mass: src/stoichiometry/Element.java
• StringTable to draw a table in ascii: src/output/StringTable.java

Sample output of the program:
