Question

part 3: match the term to the correct description. 1. homogeneous mixture blank 2. element blank b 3. compound blank a 4. heterogeneous mixture blank 5. nonmetal blank a) a substance made up of two or more elements combined in a definite proportion. b) a substance made up of only one kind of atom. c) a mixture in which the components are not uniformly distributed. d) a mixture in which the components are not uniformly distributed. e) a material that is typically brittle and poor at conducting heat and electricity.

Explanation:

1. A homogeneous mixture has uniform composition throughout, so it matches with no description here.
2. An element is made up of only one - kind of atom, so it matches with b.
3. A compound is made up of two or more elements combined in a definite proportion, so it matches with a.
4. A heterogeneous mixture has components that are not uniformly distributed, so it matches with c.
5. Non - metals are typically brittle and poor at conducting heat and electricity, so it matches with e. A mixture where components are not uniformly distributed is a heterogeneous mixture (already matched with c), and there is no other description for the type of mixture in d.

Answer:

1. No match
2. b. A substance made up of only one kind of atom.
3. a. A substance made up of two or more elements combined in a definite proportion.
4. c. A mixture in which the components are not uniformly distributed.
5. e. A material that is typically brittle and poor at conducting heat and electricity.
