Three Chemistry 10 special topics in one sim, selected with the topic parameter. Chemical thermodynamics: change the temperature to see at what point ΔG = ΔH − TΔS for the lime-roasting reaction CaCO₃ → CaO + CO₂ changes sign and the reaction becomes spontaneous. Chemistry in fire and explosion prevention: the fire triangle and the explosive concentration range of methane, LPG and hydrogen — click the ignition source to see whether a fire or explosion occurs, and choose a suitable extinguishing agent. Chemistry and IT practical: drag experimental data points so the computer builds a calibration curve A = ε·l·C, computes the correlation coefficient, and works out the concentration of an unknown sample.
