Question

Which phrase best describes bronze?

o a pure metal

o a copper-tin alloy

o a mineral ore containing copper and tin

an ionic compound of copper and tin

Answer 1

o A copper-tin alloy

Step-by-step explanation:

• Bronze is composed by copper and tin. This means it is not a pure metal.

• Bronze cannot be mined, so it is not a mineral ore.

• An ionic compound of copper and tin could also be theoretically used to describe a non-solid ionic compound of copper and tin. However bronze is solid.

• Hence the answer is A copper-tin alloy.
