1. copper (II) hypochlorite - CuClO2 Copper is a transition metal. The Roman Numeral 2 means that copper has a positive 2 charge. Hyopochlorite is a polyatomic ion with a negative 1 charge. When charges are crossed down, copper gets the 1 and hypochlorite gets the 2. This makes the formula for Copper (II) hypochlorite CuClO2

2. nitrous acid - HNO2 Nitrous acid follows the second rule for naming acids. H is hydrogen. NO2 is nitrite. because nitrite ends in -ite, the ending is changed to -ous. Hydro- is dropped and acid is added to the end of the name. 3. HClO4 - Perchloric acid HClO4 follows the third rule for naming acids. Because perchlorate ends in -ate, the -ate is changed to -ic. Hydro- is dropped and acid is added to the end of the name, making HClO4 Perchloric acid. 4. NiOH - Nickel (I) hydroxide Nickel is a transition metal and needs a Roman Numeral. Hydroxide is a polyatomic ion with a negative 1 charge. Therefore, nickel has to have a positive 1 charge. This needs to be stated in the name, so NiOH is Nickel (I) hydroxide.
