Answer: Please see explanation column for answer
Explanation:
--This is because prefixes are ” mono-” which indicates one, “di-” which indicates two, “tri-” indicates three, “tetra-”indicates four, “penta-” indicates five, and “hexa-”indicates six, “hepta-” indicates seven, “octo-” indicates eight, “nona-” indicates nine, and “deca” indicates ten.
---IT is necessary to use prefix because they show the the number of a given element present in the compound.
----when there are no ionic charges to balance out in molecular compounds, we use prefixes to name the compound
eg N2O5 = dinitrogen pentoxide
- it makes it easier to naming molecular compounds for examples while indicating number of atoms present----SO2 is sulfur dioxide and SF6 is called sulfur hexafluoride
Answer:
1)Prefixes are needed to indicate the number of atoms of each
2)if a molecule contains more than one atom of both elements, then prefixes are used for both.
3)In some names, the final a or o of the prefix is dropped to avoid awkward pronunciation.
Explanation:
NB: To buttress 2) N2O3 is dinitrogen trioxide
-To buttress 3) OsO4 is osmium tetroxide rather than osmium tetraoxide
