Question

in science, jill is learning about solids such as brass, bronze, and steel. how should she classify these materials?
a pure substances
b state compounds
c homogeneous mixtures
d heterogeneous mixtures

Explanation:

Brass is an alloy of copper and zinc, bronze is an alloy of copper and tin, and steel is an alloy of iron and carbon. Alloys are homogeneous mixtures as their composition is uniform throughout. Pure substances have a fixed composition (e.g., elements like gold or compounds like water). State compounds is not a valid classification term. Heterogeneous mixtures have non - uniform composition (e.g., a mixture of sand and water).

Answer:

C. homogeneous mixtures
