The Chemical Equation Module supports special formatting and symbols used in chemical equations, such as multi-level subscripts and stacked superscripts and subscripts for nuclear chemistry. It can be used for static display or for graded entry.

  1. Grab. Select to move contents of the module within the entry field. Select the tool and then click on the equation and hold while moving the mouse.
  2. Superscript. Highlight text and click to superscript it or click to open the superscript editing area (shortcut: press "shift" and "6"). Note: this editor provides a special feature that allows for multi-level superscripting. To escape superscript mode, use the right keyboard arrow or click on the main line.
  3. Subscript. Highlight text and click to subscript it, or click to open subscript editing area (shortcut: press "shift" and "-"). Note: this editor provides a special feature that allows for multi-level subscripting. To escape subscript mode, use the right keyboard arrow or click on the main line.
  4. Isotope. Allows for mass numbers and atomic numbers to be written as stacked and generates super-subscripts for nuclear chemistry.
  5. Stacked fraction. Converts mainline fractions to stacked fractions.
  6. Bonds. Inserts a double bond at the cursor.
  7. Multiplication dot. Inserts multiplication or hydrate dot at the cursor, as in Na2B4O7 Â· 5H2O.
  8. Greek alphabet menus. Click to open menu with Greek letters, which can then be inserted at the cursor. Both upper and lower case are available.
  9. Physical states menu. Click to select from a menu of standard physical states, such as (aq) for aqueous.
  10. Reaction arrows menu. Select from a menu of forward/backward, weighted, and equilibrium arrows. To add a symbol over arrows, place the cursor next to the arrow and use the keyboard arrows to place an entry box above arrows.
  11. Create algo. Highlight text or number(s) and click to make algorithmic variables. 
  12. Insert-algo menu. Click the green arrow to view and select available algorithmic variables from the drop-down menu.
  13. Grading status. Changes the module between  static,  graded, and  interactive.
  14. Revert. Removes changes made to the module in the current tab.
  15. Delete. Removes this module from the stage.
