When you have a covalent compound. For example, N2O3 would me Dinitrogen trioxide. Always remember, 1. Identify metal, non-metal 2. write out element names 3. If both are non-metal (covalent), count how many of each element there is 4. Place the proper prefix in front of each element.
You use the Latin prefixes when implying a number, such as in chemistry.
Example....
NO2......Nitrogen dioxide.
There are two oxygen molecules, so di is used.
H3O.......Hydrogen trioxide.
Mono-1
di-2
tri-3
tetra-4
penta-5
hexa-6
hepta-7
octa-8
nona-9
deca-ten.
All these indicate the number of molecules in a compound. Remember, however, that you only apply prefixes in chemistry to non-metal non-metal compounds.

A few examples are adenosine triphosphate and adenosine diphosphate (ATP and ADP, respectively).
Ionic compounds do not have prefixes but covalent compounds have prefixes. “Aluminum chloride” is a ionic compound and "boron tri-chloride” is a covalent compound.
yeah.. mono-1 di-2 tri-3 tetra-4 penta-5 hexa-6 hepta-7 octa-8 nona-9 deca-10 dodeca-20 The real answer is NO. The prefixes are only used in Type III compounds which are Covalent Bonds. Ionic Bonds only need the ending -ide.
Prefixes in a name generally indicate the number of atoms of a certain element in a compound. For example, carbon dioxide has two atoms of oxygen and one atom of carbon.
No, formulas of ionically bonded compounds can be figured out without prefixes and understanding of how many electrons are gained/lost. In covalent bonds, prefixes are needed and without them the formulas and quantities couldn't be determined.
Almost always. Especially when there are more than one atom of the first element in the compound.
Covalent compounds, particularly binary compounds consisting of two nonmetals, use prefixes in their names to indicate the number of atoms of each element present in the molecule. This helps distinguish between similar compounds with different ratios of atoms.
Ionic compounds do not have prefixes but covalent compounds have prefixes. “Aluminum chloride” is a ionic compound and "boron tri-chloride” is a covalent compound.

The group of compounds that use only high energy molecules is called mitochondria. They are commonly known as ATP which is short for Adenosine Tri-Phosphate.
two ions can combine in only one combination
Almost always. Especially when there are more than one atom of the first element in the compound.
I assume you're talking about prefixes in chemistry. When naming covalent, or molecular compounds, prefixes are necessary because there are different ways that the non-metals can bond with other non-metals. Here are the prefixes most often used in covalent compounds: mono=1 di=2 tri=3 tetra=4 penta=5 hexa=6 hepta=7 octa=8 nona=9 deca=10. For example, N2O4 is "dinitrogen tetroxide." *A noteworthy exception: if there's only one of the first atom, you DON'T use the mono-prefix; you simply don't use a prefix. Example: carbon monoxide means one carbon, one oxygen.
The prefix "pre-" indicates an earlier point in time or process (e.g. pre-nuclear military strategy).
They use a tri beam scale.
