A compound is a pure substance composed of two or more elements, combined by chemical means, in a definite ratio. In the model, you see four elements combined in different combinations and ratios to produce four compounds. Which of the compounds would have the formula NO2?

Question

A
B
C
D

Answer 1

To determine which compound has the formula NO2, we need to look for a combination of nitrogen (N) and oxygen (O) in a 1:2 ratio, which corresponds to one nitrogen atom and two oxygen atoms.

If you provide me with the options (A, B, C, D) along with their respective elemental compositions or descriptions, I will be able to identify which one corresponds to the formula NO2.
