You can also test your knowledge of the periodic table with an element jigsaw puzzle. You can use laboratory reagents to test known and unknown samples on the web-based lab bench. You can use laboratory reagents to test known and unknown samples on the web-based lab bench, with the same user interface as the anion applet.
Analysis is performed using a sulfide precipitation scheme.
The applet allows you to test possible chemical reactions and decide which ones can be used with Hess's Law to determine the heat of formation of magnesium oxide. It also includes enthalpy diagrams and other thermodynamic cycles, such as the Born-Haber cycle for sodium chloride. This applet is used in week 1 of Chem 6. The applet allows you to enter kinetic data and plot absorbance or concentration vs. time, natural log of concentration vs. time, or the inverse of concentration vs. time. This will allow you to quickly evaluate the reaction order since these are the expected linear plots for zero, first, and second order reactions, respectively.
