Solution Steps

Step 1: Identify the Classification of Calcium Carbonate

Calcium carbonate is a compound because it consists of three elements (calcium, carbon, and oxygen) in a fixed mass ratio.

Step 2: Identify the Classification of Oxygen

Oxygen is an element because it consists of oxygen atoms combined into diatomic molecules.

Step 3: Identify the Classification of Confectioner's Sugar

Confectioner's sugar is a mixture because it contains 6-7% cornstarch and 92-93% powdered sugar by volume.

Final Answer

\[ \begin{array}{|c|l|} \hline \text{Substance} & \text{Classification} \\ \hline \text{Calcium carbonate} & \text{Compound} \\ \hline \text{Oxygen} & \text{Element} \\ \hline \text{Confectioner's sugar} & \text{Mixture} \\ \hline \end{array} \]
