question 15 1 pts the compound scl₅ is named sulfur pentachloride monosulfur pentachloride sulfur(iv)chloride sulfur chloride question 16 1 pts which of the following is a molecular compound? lioh zns nacn p₄o₁₀ sri₂

Explanation:

For Question 15: In naming binary molecular compounds, prefixes are used to indicate the number of atoms of each element. The prefix "penta -" means 5. For sulfur and chlorine compound with 1 sulfur and 5 chlorines, it is named sulfur pentachloride. The prefix "mono -" is usually not used for the first - named element when there is only one atom of it. Sulfur(IV)chloride is an incorrect naming convention for this compound as it is a molecular compound and not named using Roman numerals in this context. Just "sulfur chloride" is too general as it doesn't specify the number of chlorine atoms.
For Question 16: Molecular compounds are formed between non - metals. LiOH is an ionic compound with a metal (Li) and a polyatomic ion. ZnS is an ionic compound with a metal (Zn) and a non - metal (S). NaCN is an ionic compound with a metal (Na) and a polyatomic ion. $P_4O_{10}$ is a compound formed between non - metals (phosphorus and oxygen), so it is a molecular compound. SrI₂ is an ionic compound with a metal (Sr) and a non - metal (I).

Answer:

Question 15: sulfur pentachloride
Question 16: $P_4O_{10}$
