| Binary Acids | Formed when some gaseous compounds containing hydrogen are dissolved in water |
| Naming Binary Acids | Prefix hydro + anion nonmetal root + suffix -ic + the word acid (ex. HBr - hydrobromic acid) |
| Oxoacids | Formed when hydrogen ions combine with a polyatomic ion |
| Naming Oxoacids | Name based on polyatomic ion "-ate" is replaced with -ic acid "-ite" is replaced with -ous acid |
| Determining Empirical Formula | -Assume you have 100.0g sample so all % given can be converted to grams -Use atomic weights to convert g to mols of each element -Divide each number of mols by smallest number of mols present -Dividends are subscripts in chemical formula |
| Diatomic Elements | H2, N2, O2, F2, Cl2, I2, Br2 |
