Final answer:
The only matching formula and name from the given options is c) SrO: Strontium (II) oxide. Other correct name and formula pairs are provided for comparison and clarity.
Step-by-step explanation:
The question involves determining which of the given options has the correct chemical formula that matches its chemical name. Upon reviewing the options, the correct one is c) SrO: Strontium (II) oxide. This is because strontium is a group 2 element and forms +2 cations, and oxygen is typically a -2 anion. The formula SrO indicates one Sr2+ ion combining with one O2- ion, which agrees with the name strontium (II) oxide.
For the other options, the correct formula and name pairs based on the provided reference information would be:
a) Fe2S3: iron(III) sulfide
b) CuSe: copper(II) selenide
c) GaN: gallium(III) nitride
d) MgSO4.7H2O: magnesium sulfate heptahydrate
e) Ti2(SO4)3: titanium(III) sulfate
