given the name of a binary molecular compound, describe how to write its formula. Use carbon tetrachloride as an example.
prefixes are used when writing the names of binary molecular compounds, such as carbon tetraccloride. The prefix tells how many atoms of an element are present in each molecule of the compound. You then write the symbol an dhte subscript according to the prefixes. Ex: CCl4
