 Iron (III) Nitride Co2O3 FeN Cobalt (III) Oxide

 Copper (I) Bromide SnS CuBr Tin(II) Sulfide

 Circle the correct chemical formula for each compound below. Make sure the positive and negative charges are balanced. o calcium oxide CaO Ca2O CaO2 o magnesium fluoride MgF Mg2F MgF2 o sodium sulfide NaS Na2S NaS2 o barium nitride BaN Ba2N3 Ba3N2

Naming Acids  If the compound begins with Hydrogen, it is an acid. If the acid does not contain a polyatomic ion, write the prefix hydro-, then name the second element and change the ending to –ic.’ o HCl hydrochloric acid

o HBr hydrobromic acid

o H2S hydrosulfuric acid

Naming Acids with Polyatomic Ions The polyatomic ions you have memorized have –ate as the ending, so you name the polyatomic ion and change the ending to –ic.

2- Use sulfate (SO4 ) as the example  H2SO4 is sulfuric acid 2-  If the ion has one more oxygen atom than the base Persulfate (SO5 ), then the ion is named by adding the prefix per- and the suffix –ic o H2SO5 is persulfuric acid 2-  If the ion has one less oxygen atom than the base Sulfite (SO3 ), then the ion is named with the suffix –ous.

2

o H2SO3 is sulfurous acid 2-  If the ion has two less oxygen atoms than the base Hyposulfite (SO2 ), then the ion is named with the prefix hypo- and the suffix –ous. o H2SO2 is hyposulfurous acid Name the following: H2CO3 H3PO2 Cabonic acid Hypophosphorous acid

HClO4 H3PO3 Perchloric acid Phosphorous acid
