Answer
Explanation:
Step1: Identify strontium compounds
Strontium is Sr. Sulfate is $SO_4^{2 - }$, sulfide is $S^{2 - }$, selenide is $Se^{2 - }$. So strontium sulfate is $SrSO_4$, strontium sulfide is $SrS$, strontium selenide is $SrSe$.
Step2: Identify sodium compounds
Sodium is Na. Sodium sulfide has two sodium ions to balance the - 2 charge of sulfide ion, so it is $Na_2S$. Sodium sulfate has two sodium ions to balance the - 2 charge of sulfate ion, so it is $Na_2SO_4$. Sodium selenide has two sodium ions to balance the - 2 charge of selenide ion, so it is $Na_2Se$.
Answer:
SrS - strontium sulfide $Na_2SO_4$ - sodium sulfate $Na_2S$ - sodium sulfide $SrSO_4$ - strontium sulfate $SrSe$ - strontium selenide $Na_2Se$ - sodium selenide
