Final answer:
Among the choices given, 'd. stannic fluoride, SnF₄' is the only correctly named compound with its corresponding formula. The other compounds have incorrect formulas for the names provided.
Step-by-step explanation:
The correct name and formula among the choices given is d. stannic fluoride, SnF₄. This compound is correctly named because "stannic" indicates tin with a +4 oxidation state, and fluoride refers to the ion F−. Therefore, the formula SnF₄ correctly represents tin(IV) fluoride where one tin ion combines with four fluoride ions to form the ionic compound.
Let's correct the incorrect options:
- a. Sodium oxide should be Na2O, not NaO.
- b. Barium nitride should be Ba3N2, not BaN.
- c. Cobaltous chloride, if it refers to cobalt(II) chloride, should be CoCl2, not CoCl3. "Cobaltous" indicates the +2 oxidation state of cobalt.
