Final answer:
Bottled seltzer water is a solution, fog and blood are colloids, and mint chocolate chip ice cream is a heterogeneous mixture.
Step-by-step explanation:
The substances can be classified as follows:
- Bottled seltzer water: Solution.
- Fog: Colloid.
- Blood: Colloid.
- Mint chocolate chip ice cream: Heterogeneous mixture.
A solution is a homogeneous mixture where the particles are of small size, like in bottled seltzer water. A colloid is a heterogeneous mixture where the particles are larger, like in fog and blood. Mint chocolate chip ice cream is a heterogeneous mixture because it contains visible particles, mint ice cream, and chocolate chips.
