Iron = Fe not fe. • Enter formulas without subscrips: CaCl2 = CaCl2, K2SO4 = K2SO4 • Monoatomic ions do not require parentheses. Correct: Na2CO3. Incorrect: (Na)2CO3 •Polyatomic ions only require parentheses when there are two or more. Correct: Na3PO4. Incorrect: Na3(PO4), Correct: NH4NO3. Incorrect: (NH4)(NO3). correct: Ca3(PO4)2 • In each case one product is soluble (aq) and one insoluble (s). Use solubility rules to determine which product appears in each box. ____Pb(C2H3O2)2 (aq) + ____ KI (aq) ➝ _____  ____________(aq) + ____  _________________(s)
