Question

1. what is an element?

a substance with fixed composition
two or more elements chemically combined
the simplest form of matter from which more complex substances are made
a mixture with variable composition

1. what is a homogeneous mixture?

a mixture where components are evenly distributed
a mixture where substances are not evenly spread out
a mixture where small particles remain dispersed throughout
a mixture where larger particles settle out over time

Explanation:

For question 7: An element is the fundamental, simplest form of matter that cannot be broken down into simpler substances by chemical means, and it serves as the building block for more complex substances. The other options describe a pure substance (too broad), a compound, and a mixture respectively.
For question 8: A homogeneous mixture is defined by its uniform composition, where all components are evenly distributed at the molecular level, resulting in a consistent appearance and properties throughout. The other options describe heterogeneous mixtures, colloids, and suspensions respectively.

Answer:

1. The simplest form of matter from which more complex substances are made
2. A mixture where components are evenly distributed
