![]() ![]() See this article to learn more about how to Search Chemical Structures contained in Widgets or attachment entries. Doing this will clear all the values from the cells. You can remove the tables by clicking the ‘Remove Stoichiometry Table’ button under the chemical sketcher canvas. Overwriting the table will reset the table and clear all values from the cells. These are caused by uncertain/incorrect user input.Ĭlicking ‘Create Stoichiometry Table’ after a table has already been generated will produce a window with an option to overwrite the current table. In some cases, you may encounter flagged results that will appear as red in the table. Note: You cannot edit the values for the Formula or Molecular Mass cells. Note: Some fields may be unitless.Īfter defining a value and unit, press the enter key on your keyboard or click anywhere else in the widget. By default, the Formula and Molecular Mass will automatically be filled for you. Hover over and click on a cell to see a pop up where you can enter a value and unit. They are self-calculating, chemically aware and will maintain proper balancing while editing. These tables serve as forms that help you calculate different values for a reaction. To create your stoichiometry table, click the ‘Create Stoichiometry Table’ button. After drawing a chemical reaction, you can create a stoichiometry table to quickly calculate multiple parameters of the reaction drawn. ![]() Stoichiometry allows you to understand the relative quantities of each substance that takes part in a reaction or a compound that is formed – as making these calculations by hand can be time consuming and can be error prone. You can quickly add many copies of the same structure if needed. Using the Cut/Copy/Paste structure tools, you can more easily move and replicate structures. This can help you position molecules for some reaction more easily. Using the Flip Structure tools, you can flip any selected molecule vertically or horizontally. Many types of arrows, including curved arrows, straight arrows, equilibrium arrows, single electron, and electron pair arrows are available. Using the Arrow Tool, you can draw arrows of several different types to help represent the different steps of your reaction. When you do this, the text will automatically format itself with the proper subscripts (in this case ‘C6H12O6’ becomes ‘C 6H 12O 6’). You can also write some chemical formula (eg ‘C6H12O6’). Using the Text annotator, you can label structures, describe reaction conditions, and do any other number of things that can be shown in linear text. These tools include the Text Annotator, the arrow tool, the Flip Structure tools, and the Copy/Paste Structure tools. Once you have drawn your structures, there are a variety of other tools you can use to help annotate your structures and construct a cohesive representation of a chemical reaction. See information on how to import and export MOL files below. In addition to the above tools, you can save entire molecular structures to your local hard drive and re-load them to the Chemical Sketcher Widget canvas later using the Save MOL file and Load MOL file tools. A number of structures are already available to you and are organized into separate chemical categories. Using the Templates Database, you can add entire named structures quickly to the canvas. You can then add more fused rings if you wish, or use other structure editing tools to modify the rings as needed. Using the Cyclic Builder, you can quickly add cyclopentane, cyclohexane, and benzene rings right onto the canvas. Using the Carbon Chain tool, you can quickly construct a hydrocarbon chain with as many carbons as you can fit in the canvas. These are the Carbon Chain tool, the Cyclic Builder, and the Molecular Templates. You can quickly build more complex structures by using additional tools available in the canvas. You can also add radicals and lone pairs using this tool. You can modify the charge as positive or negative by opening the drop down menu to the right of the charge icon. To modify the charge on any atom, use the Charge tool, as shown here. The bonds themselves can be modified with the bond line tool, shown here. You can also draw bonds between atoms with this tool. You can select from any element on the periodic table, as shown below. ![]() To change the element selected, open the drop down by clicking the arrow on the right. Any atom of any element can be placed on the canvas with this tool. You can draw a structure atom by atom using the Point-Drawing tool. ![]() You can use it to draw bond-line representations of molecules and molecular reactions. ![]()
