question 3 of 10\nwhich option correctly matches the chemical formula of a compound with its name?\na. n₂o₅, dinitrogen pentoxide\nb. n₂o₅, nitrogen oxide\nc. n₂o₄, nitrogen oxide\nd. n₂o₄, dinitrogen pentoxide

Answer

Explanation:

Step1: Analyze naming rules for covalent compounds

For covalent compounds, the prefixes indicate the number of atoms. "Di - " means 2, "penta - " means 5.

Step2: Check each option

  • Option A: (N_2O_5), "di" for 2 (N) atoms ((N_2)), "penta" for 5 (O) atoms ((O_5)), so dinitrogen pentoxide is correct.
  • Option B: (N_2O_5) should be dinitrogen pentoxide, not nitrogen oxide (which is too general, no prefixes indicating atom numbers).
  • Option C: (N_2O_4) should be dinitrogen tetroxide (tetra - for 4 (O) atoms), not nitrogen oxide.
  • Option D: (N_2O_4) is dinitrogen tetroxide, not dinitrogen pentoxide ((N_2O_5) is dinitrogen pentoxide).

Answer:

A. (N_2O_5), dinitrogen pentoxide
