Question

a compound has the empirical formula given below. no₂ which compound represents the molecular formula with a scale factor of 2? n₂o₄ n₂o₂ no₄

Explanation:

Step1: Multiply each subscript in the empirical formula by the scale factor

The empirical formula is \(NO_2\). Multiply the subscript of \(N\) (which is \(1\)) and the subscript of \(O\) (which is \(2\)) by the scale factor \(2\).
For \(N\): \(1\times2 = 2\)
For \(O\): \(2\times2=4\)

Answer:

\(N_2O_4\)
