Question

chemistry semester 1 exam on level 25-26
which of the following is the correct formula for tetrasulfur dinitride?
○ sn₄
○ s₂n₄
○ sn
○ s₄n₂

Explanation:

Step1: Analyze prefixes

"tetra-" means 4, "di-" means 2. For tetrasulfur dinitride, sulfur (S) has a subscript of 4, nitrogen (N) has a subscript of 2.

Step2: Form the formula

Combine S with subscript 4 and N with subscript 2, giving \( S_4N_2 \).

Answer:

\( S_4N_2 \) (the last option, e.g., D. \( S_4N_2 \) if options are labeled D for the last one)
