Nomenclature Formula-to-Name Solutions
The key to solving these types of problems correctly is first determining whether the molecule is ionic or molecular. If it consists of two nonmetals, then it is molecular like numbers 2 and 14. In these cases, we must use the prefixes. In the others, we simply use the ionic compound rules to find the names.
CaCO3: calcium carbonate
SCl2: sulfur dichloride
Li2CrO4: lithium chromate
NaSCN: sodium thiocyanate
KClO3: potassium chlorate
Ca(C2H3O2): calcium acetate
K2Cr2O7: potassium dichromate
Mg3(PO4)2: magnesium phosphate
Ba(NO2)2: barium nitrate
Hg2Cl2: mercury(I) chloride
NaHCO3: sodium bicarbonate
H2S: hydrosulfuric acid
H2SO3: sulfurous acid
SO3: sulfur trioxide
