Question

select all the correct answers. which three statements are true about all alloys? theyre made from metals combined in equal amounts. theyre harder than the pure metals theyre made of. theyre good conductors of electricity. theyre brittle and prone to cracking. they have a metal as their main component.

Explanation:

Alloys are defined as mixtures with a metal as the main component (E). They retain metallic properties like electrical conductivity (C) and generally have increased hardness compared to pure metals (B). Equal amounts (A) are not required, and brittleness (D) is not universal.

Answer:

B. They're harder than the pure metals they're made of, C. They're good conductors of electricity, E. They have a metal as their main component
