Explanation:

Step1: Classify tossed salad

A tossed salad has distinct, visible components (e.g., lettuce, veggies, dressing) that are not evenly distributed at a microscopic level, so it is a heterogeneous mixture.

Step2: Classify carbon dioxide

Carbon dioxide ($\text{CO}_2$) is a pure substance made of two different elements (carbon and oxygen) chemically bonded in a fixed ratio, so it is a compound.

Step3: Classify salad

A general salad has separate, identifiable components that are not uniformly mixed, so it is a heterogeneous mixture.

Answer:

1. a. Heterogeneous mixture
2. d. Compound
3. a. Heterogeneous mixture
