Final answer:
The correctly matched chemical formulas are SO2 for sulfur dioxide and AlF3 for aluminum trifluoride. The other three compounds, lithium nitride, hydrogen sulfite, and dihydrogen monoxide have incorrect formulas listed.
Step-by-step explanation:
Among the list of chemical compounds and their formulas, correct matches are as follows:
- c) SO2 sulfur dioxide - Correctly matched. SO2 is the formula for sulfur dioxide, a compound consisting of one sulfur atom and two oxygen atoms.
- d) AlF3 aluminum trifluoride - Correctly matched. AlF3 is the formula for aluminum trifluoride, consisting of one aluminum atom and three fluorine atoms.
The other compounds in the list are incorrectly matched:
- a) LizN lithium nitride should be Li3N, which is the proper formula for lithium nitride.
- b) H2S hydrogen sulfite should be hydrogen sulfide since sulfite is a polyatomic ion with the formula SO32-.
- e) H2O dihydrogen monoxide is a less common name for water, which is typically just called water or dihydrogen oxide.
