1 Chemical Formula Writing Worksheet #2 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. chloride ZnCl 2 acetate nitrate oxide nitride sulfate zinc iron (II) iron (III) gallium silver lead (IV) 1) silver carbonate 2) potassium hydrogen phosphate 3) aluminum hydroxide 4) sodium hydrogen carbonate 5) calcium acetate 6) potassium permanaganate 7) calcium perchlorate 8) lithium carbonate 9) magnesium hydrogen sulfite 2 E-Book Page 576
