Explain how bases are named.
Just like ionic compounds. Write the name of the cation first followed by the name of the anion.

Explain how to write an ionic formula, given an anion and a cation. As an example, use the nitrate anion.
The symbol for the cation is written first, then the symbols for the an anion second. Use subscripts to balance the charges of the ions so an electrically neutral substance results.

Given the name of a binary molecular compound, describe how to write its formula. Use Nitrogen dioxide as an example.
Begin by writing the chemical symbol for the first element in the compound name on the left, and then write the chemical symbol for the next element on the right. Prefixes that describe elements in the compound names determine the subscripts for those elements.

Explain the three rules to naming acids. Use HBr, H2CrO4, and HNO2 as examples.
If the name of the anion ends in ide - add hydro to the beginning and change ide to ic. (Hydrobromic acid) If the name of the anion ends in ate - change it to ic (chromic acid) If the name of the anion ends in ite - change it to ous. (nitrous acid)
