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 presentSO2 is sulfur dioxide and SF6 is called sulfur hexafluoride

Answer from: fayechadx

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

Answer from: Quest

answer: e. sour taste

explanation: acids are those substances which dissociates in water to give $h^+$ ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

$hcl\rightarrow h^++cl^-$

bases are those substances which dissociates in water to give $oh^-$ ions or accepts $h^+$ ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.

$naoh\rightarrow na^++oh^-$

$nh_3+h^+\rightarrow nh_4^+$
