Problem

A substance composed of two or more elements in a fixed, definite proportion is:

A. a homogeneous mixture
B. a heterogenous mixture
C. a compound
D. a solution
E. an alloy

Solution

We're being asked to determine the substance that can't be chemically broken down into simpler substance.


Recall that Matter can be categorized as a single or variable composition.

• Matter is considered a pure substance if it is composed of a single entity. Pure substances can be further categorized into two:

Element
Compound

• Matter is considered a mixture if they have variable composition. Mixtures are not chemically combinedMixtures can be further categorized into two:
