Explanation:

Question 10 (N₂F₄ Naming)

Step1: Identify Elements and Prefixes

N is nitrogen, F is fluorine. Subscripts: 2 for N, 4 for F. Prefixes: "di-" for 2 (nitrogen), "tetra-" for 4 (fluorine). Adjust for covalent compound naming (non - metal + non - metal, use prefixes).

Step2: Combine Names

Nitrogen (di - for 2) and fluorine (tetra - for 4, change - ine to - ide). So name is dinitrogen tetrafluoride.

Step1: Identify Elements and Prefixes

C is carbon, O is oxygen. Subscript for O is 2. For covalent compounds, carbon (no prefix as subscript 1), oxygen with prefix "di - " (subscript 2), change - gen to - ide.

Step2: Combine Names

Carbon + di (for 2 O) + oxide. So name is carbon dioxide.

Step1: Identify Elements and Prefix Meanings

Sulfur (S) and fluorine (F). "Di - " means 2 for fluorine. Sulfur has no prefix (implies 1 atom).

Step2: Write Formula

S (1 atom) and F (2 atoms). So formula is SF₂.

Answer:

dinitrogen tetrafluoride
