Question

question 23 (0.25 points) listen what is the correct formula for the compound with the name: trisilicon tetranitride a) s₄ni₃ b) si₃n₄ c) s₃ni₄ d) si₄n₃ e) s₃n₄ f) s₄n₃

Explanation:

1. Identify the elements: "trisilicon" refers to silicon (Si), "tetranitride" refers to nitrogen (N).
2. Use prefixes to find subscripts: "tri-" means 3, so there are 3 Si atoms; "tetra-" means 4, so there are 4 N atoms.
3. Write the formula with the cation (silicon) first, followed by the anion (nitride), with subscripts matching the prefixes.

Answer:

b) $\text{Si}_3\text{N}_4$
