Chemistry Utility

This is what the chemistry database application building has been for - this application serves to automate much of the possibly tedious lookups and calculations involved in general chemistry.

Features of Finished Application

• stoichiometry
• balancing of formulae
• molarity calculations
• information lookup
• temperature conversions
• mass and volume conversions
• free energy
• gas laws
• reactivity
• entropy
• possibly some templates for common procedures like titration or gas generation measurement

Usage Examples

Returns data available from the infoboxes on Wikipedia:
print_lookup('Al2(SO4)3')
print_lookup('CuSO4')
print_lookup('H2SO4')
print_lookup('Hydrogen')
print_lookup('donald duck')
print_lookup('toast')

Returns the amount of moles for a given mass of a substance print_moles_substance(36.4, 'CuSO4')
print_moles_substance(100, 'H2O')
print_moles_substance(molar_mass('H2O'), 'H2O') This will always return 1 as long as the input substances match

Returns the mass of a given amount of moles of a substance
print_mass_substance(2, 'MgSO4(H2O)7') mass of 2 moles of magnesium sulfate heptahydrate

Any of the following formats are fine:
print_balance_chemical_formula('C2H6 + O2 --> CO2 + H2O')
print_balance_chemical_formula('C4H10 + O2 -> CO2 + H2O')
print_balance_chemical_formula('FeCl3 + NH4OH > Fe(OH)3 + NH4Cl')
print_balance_chemical_formula('P2I4 + P4 + H2O --> PH4I + H3PO4')
print_balance_chemical_formula('Cu+HNO3-->Cu(NO3)2+NO2+H2O')
print_balance_chemical_formula('S+HNO3-> H2SO4 + NO2 + H2O')

Solves stoichiometry calculations (automates balancing, moles conversions, and substance ratios):
print_stoichiometry('C6H12O6 + O2 --> CO2 + H2O', 'O2', 1.03*(10**-2), 'C6H12O6') Grams of glucose the human body consumes each minute if 1.03 x 10^-2 mol O2 is used for cellular respiration each minute
print_stoichiometry('CuSO4 + Al --> Al2(SO4)3 + Cu', 'CuSO4', moles_substance(5, 'CuSO4(H2O)5'), 'Al') How much aluminum is needed to react with 5 grams of copper(II) sulfate pentahydrate?
print(moles_to_liters_gas(stoichiometry('C2H6 + O2 --> CO2 + H2O', 'C2H6', moles_substance(20, 'C2H6'), 'O2')['moles']), 'liters of O2 gas at STP') How many liters of O2 is needed to react with 20 g of ethane?

Returns the given piece of information for an element:
periodic_table_retrieve('melt', 'Au')

Performs a search of the closest term in the periodic table to what's looked up:
print_periodic_table_closest(1337, 10)
print_periodic_table_closest(39.6, 8, 'weight')

Returns the potentially available pieces of information for each element:
print(get_periodic_table_details_list())
