![]() Add or remove heat and watch the phase change. Watch different types of molecules form a solid, liquid, or gas. Change the bond angle to see how shape affects polarity. See how the molecule behaves in an electric field. When is a molecule polar? Change the electronegativity of atoms in a molecule to see how it affects polarity. How do you know if a chemical equation is balanced? What can you change to balance an equation?īuild an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Can a weak acid solution have the same pH as a strong acid solution? Then see how concentration and strength affect pH. How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. At EDinformatics we are transitioning from Java, Shockwave and Flash to HTML5 Simulations which can easily be used on all platforms. ![]() JavaScript, HTML5, and other scripting languages have managed to take over applets both in terms of browser support and extra functionality. With Java applets on the decline for many years.
