Question

which option correctly matches the chemical formula of a compound with its name?
a. n₂o₄, dinitrogen pentoxide
b. n₂o₅, nitrogen oxide
c. n₂o₄, nitrogen oxide
d. n₂o₅, dinitrogen pentoxide

Explanation:

• For binary covalent compounds (compounds between non - metals), the naming rule is: the first element's name is given as is, the second element's name has the suffix "-ide". And we use prefixes to indicate the number of atoms of each element.
• The prefix "di -" means 2 and "penta -" means 5.
• In \(N_2O_5\), there are 2 nitrogen (\(N\)) atoms and 5 oxygen (\(O\)) atoms. So its name is dinitrogen pentoxide.

Answer:

D. \(N_2O_5\), dinitrogen pentoxide
