Question

what is the formula of the compound given below? dinitrogen tetroxide 2n4o n₂o₄ ni₂o₄

Explanation:

• In chemical nomenclature, "di -" means 2 and "tetra -" means 4.
• For dinitrogen tetroxide, "nitrogen" has the symbol \(N\) and "oxygen" has the symbol \(O\).
• So, 2 nitrogen atoms (\(N_2\)) and 4 oxygen atoms (\(O_4\)) give the formula \(N_2O_4\). The option \(2N4O\) is not in the correct chemical formula notation (subscripts are used in formulas, not numbers before the element symbols in that way). The option \(Ni_2O_4\) uses \(Ni\) which is the symbol for nickel, not nitrogen.

Answer:

\(N_2O_4\) (the second option in the given choices)
