Question

the name for the compound s₂o₄ is ____________. sulfide trioxide disulfur tetraoxide sulfur oxide disulfide tetraoxide question 19 which is the correct formula for the compound dinitrogen monoxide? n - o no₂ n₂o₂ n₂o

Explanation:

For the first question, in naming covalent compounds, prefixes are used. "Di -" means 2 (for sulfur atoms, \(S_2\)) and "tetra -" means 4 (for oxygen atoms, \(O_4\)), so \(S_2O_4\) is disulfur tetraoxide.
For the second question, "dinitrogen" means 2 nitrogen atoms (\(N_2\)) and "monoxide" means 1 oxygen atom (\(O\)), so the formula for dinitrogen monoxide is \(N_2O\).

Answer:

First question: B. disulfur tetraoxide
Second question: D. \(N_2O\)
