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 mixtures of metals or a metal and other elements. They don't need to be in equal amounts. Usually, they are harder than pure metals, are good electrical conductors as they have metal components, and have a metal as the main component. They are not always brittle and prone to cracking.

Answer:

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