Balanced! Formula is: KCl
Ca 2+ Formula is: CaBr 2 Br - Not balanced! 1(2+) + 2(1 - ) = 0
Ca 2+ S 2- Formula is: Ca 2 S 2 Reduce!! Formula is: CaS Correct!!
If an element forms more than one ion, a Roman numeral is used to indicate the charge
Zinc = Zn 2+ Silver = Ag + No Roman numeral is used for elements that have only one oxidation state
Fe 3+ O 2- Not balanced! Formula is: Fe 2 O 3 2(3+) + 3(2-) = 0
Fe 3+ O 2- Fe 2 O 3
Ca 2+ NO 3 - Ca ( NO 3 ) 2
Li + CO 3 2- Li 2 CO 3
Mg 2+ OH - Mg(OH) 2
