question 15
what type of matter do alloys fall under?
a pure substance that is ionically bonded
a pure element
mixture

Explanation:

An alloy is a combination of metals or metals with non - metals. It is not a pure substance (either an element or a compound). A pure substance has a fixed composition. An element is made of only one type of atom. A compound (which could be ionically bonded) has a fixed ratio of atoms. An alloy has a variable composition as it is a combination of different substances. So, alloys are mixtures.

Answer:

C. Mixture
