Which of the following is the correct molecular formula for ozone?
A
CO_2
B
O_2
C
NO_2
D
O_3
Verified step by step guidance1
Understand that the molecular formula represents the exact number and type of atoms in a molecule.
Recall that ozone is a molecule composed entirely of oxygen atoms.
Recognize that the common molecular formula for oxygen gas is \(O_2\), which consists of two oxygen atoms.
Know that ozone differs from oxygen gas by having three oxygen atoms bonded together, which is represented as \(O_3\).
Compare the given options and identify that \(O_3\) correctly represents ozone, while \(CO_2\) and \(NO_2\) represent different molecules (carbon dioxide and nitrogen dioxide, respectively).
