Question

how many atoms of oxygen (o) are in the compound: * carbon dioxide co₂ 1 atom 2 atoms 3 atoms

Explanation:

Step1: Analyze the chemical formula

The chemical formula of carbon dioxide is \(CO_2\). In a chemical formula, the subscript next to an element symbol indicates the number of atoms of that element in one molecule of the compound.

Step2: Determine the number of oxygen atoms

For the \(CO_2\) formula, the subscript of \(O\) (oxygen) is \(2\). This means there are 2 oxygen atoms in one molecule of carbon dioxide.

Answer:

B. 2 atoms
