Solution Steps

Step 1: Understanding Substances and Mixtures

A substance is a form of matter that has a constant composition and distinct properties. Substances can be elements or compounds. A mixture, on the other hand, is a combination of two or more substances where each retains its own properties and can be physically separated.

Step 2: Classifying Each Item
  • Oxygen: Oxygen is an element, which is a pure substance. It consists of only one type of atom, O\(_2\).
  • Sodium Sulfite: Sodium sulfite is a chemical compound, which is a pure substance. It has a definite chemical formula, Na\(_2\)SO\(_3\).
  • Smog: Smog is a mixture. It is a combination of various pollutants and particulates suspended in the air.
  • A Carrot: A carrot is a mixture. It contains various compounds such as water, carbohydrates, and vitamins, which can be physically separated.
  • Pure Milk Chocolate: Pure milk chocolate is a mixture. It is made from ingredients like cocoa, milk, and sugar, which are mixed together.
  • Rabbit Fur: Rabbit fur is a mixture. It consists of different proteins and other compounds.

Final Answer

\[ \begin{align_} \text{a. Oxygen} & : \text{Substance} \\ \text{b. Sodium Sulfite} & : \text{Substance} \\ \text{c. Smog} & : \text{Mixture} \\ \text{d. A Carrot} & : \text{Mixture} \\ \text{e. Pure Milk Chocolate} & : \text{Mixture} \\ \text{f. Rabbit Fur} & : \text{Mixture} \\ \end{align_} \]

\[ \boxed{ \begin{align_} \text{a. Substance} \\ \text{b. Substance} \\ \text{c. Mixture} \\ \text{d. Mixture} \\ \text{e. Mixture} \\ \text{f. Mixture} \\ \end{align_} } \]
