homogeneous mixture
compound
element
heterogenous mixture

Answer 1

Here’s the matching of the examples of matter with the best description:

1. **Concrete** - Heterogeneous mixture
2. **Bronze** - Homogeneous mixture (it is an alloy, typically a mixture of copper and tin)
3. **Copper** - Element
4. **Air** - Homogeneous mixture
5. **Sand, silicon dioxide** - Heterogeneous mixture (sand is typically a mixture and silicon dioxide refers specifically to the compound in its pure form)
6. **Fog** - Homogeneous mixture (though it can appear heterogeneous, it is generally considered a homogeneous mixture of water droplets in air)
