To enter a cation or anion, enter the chemical symbol of the element, followed by a carat (^) and the charge. For example, NO 3 1- would be entered as NO3^1-. Ca 2+ would be entered as Ca^2+. Please do not put parentheses around individual cations or ions. To enter a chemical formula,first enter the chemical symbol of the cation, followed by any subscript that is greater than 1. Then enter the chemical symbol of the anion, followed by any subscript that is greater than one. When entering polyatomic ions (ions composed of more than one atom), such as NH 4 1+ or CO 3 2- , please do NOT use parentheses around the polyatomic ion if only one is present. However, if more than one is required, place parentheses around the polyatomic ion and place the subscript outside the parenthese. For example, NH 4 Cl would be input as NH4Cl. (NH 4 ) 2 CO 3 would be input as (NH4)2CO3. If you wish to look at your response in "chemistry font" (with subscripts and superscripts) before you submit, click on the icon next to the answer box. You are strongly urged to do so to make sure the ion looks right.icon next to the answer box.... View Full Document
