Nomenclature 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
