Pseudo code

Problems - If store value of a property inside the object - One property can belong to two different laws. So if that property change, which law need to be change?

Example 11: What volume of \(\mathrm{CO}_2\) is generated from \(1.0 \mathrm{g}\) \(\mathrm{C}_{6}\mathrm{H}_{12} \mathrm{O}_6\) reacting at \(293 \mathrm{k}\) and \(0.984 \mathrm{~atm}\) ?

\(\mathrm{C}_6 \mathrm{H}_{12} \mathrm{O}_6 (\mathrm{s}) \rightarrow 2 \mathrm{C}_2 \mathrm{H}_{6} \mathrm{O}(l)+2 \mathrm{CO}_2(\mathrm{~g})\)

# from universe import our_universe

# system = System()

# C6H12O6 = Compound('C6H12O6', 'solid')

# C2H6O = Compound('C2H6O', 'liquid')

# CO2 = Compound('CO2', 'gas')

# open_container = OpenContainer()

# r = Reaction(reactants=[C6H12O6], product=[C2H6O, CO2],
#              catalyst=[],
#              environment=open_container, system=system)

The current timestep is None

# final_state = system.set_time(-1)

After set mass, the system auto generated all properties of other component at that timestep

# final_state.compound(C6H12O6).setMass('1.0 g')

# initial_state = system.set_time(1)

# initial_state.compound(CO2).getVolume()
