Chemical Formula Writing Worksheet Two
staff.imsa.eduChemical Formula Writing Worksheet Solutions Write chemical formulas for the compounds in each box. The names are found by finding the intersection between the cations and anions. Example: The first box is the intersection between the “zinc” cation and the “chloride” anion, so you should write “ZnCl 2”, as shown.
