What is the name for the compound SF6?
- sulfur fluoride
- monosulfur hexafluoride
- sulfur hexafluorine
- sulfur hexafluoride
Molecular compounds use prefixes to indicate how many of each element are present in that compound.
The first element drops the “mono-” prefix.
The ending of the second element is always changed to “-ide.”
Molecular compounds use prefixes to indicate how many of each element are present in that compound, but the first element drops the “mono-” prefix. Also, the ending of the second element is always changed to “-ide.”
What is the formula for boron trichloride?
- BCl
- B3Cl
- BCl4
- BCl3
Molecular compounds use prefixes to indicate how many of each element are present in that compound.
Do not crisscross molecular prefixes. The element symbol should have the same subscript as the prefix on its name.
The prefix “tetra-” means four.
The prefix “tri-” means three.
Which compound would form an acid when dissolved in water as an aqueous solution?
- HgCl2
- HCl
- NaCl
- H2
Ionic compounds consist of metal and nonmetal ions. Mercury is a metal and chlorine is a nonmetal. Acids contain H+ and an anion.
Acids contain H+ and an anion.
Ionic compounds consist of metal and nonmetal ions. Sodium is a metal and chlorine is a nonmetal. Acids contain H+ and an anion.
Diatomic elements form molecules with another atom of the same element. Acids contain H+ and an anion.
What anion would be present in hydronitric acid?
- nitride ion, N3−
- nitrite ion, NO2−
- nitrate ion, NO3−
- ammonium ion, NH4+
An acid that contains an anion ending with “-ide” will have an acid name beginning with “hydro-” and ending with “-ic.”
An acid that contains an anion ending with “-ite” will have an acid name with no prefix and ending with “-ous.”
An acid that contains an anion ending with “-ate” will have an acid name with no prefix and ending with “-ic.”
Ammonium is a polyatomic cation.
What is the name of H2SO4 (aq)?
- hydrosulfuric acid
- sulfurous acid
- sulfuric acid
- hydrogen sulfate acid
An acid whose name begins with “hydro-” and ends with “-ic” will contain an anion ending with “-ide.”
An acid whose name has no prefix and ends with “-ous” will contain a polyatomic anion ending with “-ite.”
An acid whose name has no prefix and ends with “-ic” will contain a polyatomic anion ending with “-ate.”
Acids have special endings according to the name of the anion present in the acid. A polyatomic ion ending with “-ate” would give the acid name an ending of “-ic.”
