Question

question: ____ mixtures have a constant composition.
answer input:
spelling counts but capitalization doesn’t.

Explanation:

In chemistry (a subfield of Natural Science), homogeneous mixtures (also called solutions) have a uniform and constant composition throughout.

So the type of mixture with constant composition is homogeneous.

Answer:
