Question

which particle diagram most likely shows carbon dioxide gas? o a. o b. o c. o d.

Explanation:

Step1: Recall carbon - dioxide formula

The chemical formula of carbon dioxide is $CO_2$. It consists of one carbon atom (usually represented by a black circle) and two oxygen atoms (usually represented by white circles) bonded together in a molecule.

Step2: Analyze each option

Option A shows a mixture of different molecules, not just $CO_2$. Option B shows individual atoms, not molecules of $CO_2$. Option C shows molecules where each molecule has one black (carbon) and two white (oxygen) atoms, which is consistent with the $CO_2$ molecule. Option D shows molecules with an incorrect ratio of atoms for $CO_2$.

Answer:

C.
