Step 1
What is the name for the type of substance formed?
Answer
The correct answer is A) Alloy.
An alloy is a mixture of two or more elements, where at least one of them is a metal. Alloys are formed to enhance the properties of metals, such as strength, ductility, and resistance to corrosion. Common examples include steel (an alloy of iron and carbon) and bronze (an alloy of copper and tin).
In contrast:
- Compound refers to a substance formed when two or more different elements chemically bond together.
- Solution is a homogeneous mixture where one substance is dissolved in another.
- Suspension is a heterogeneous mixture where particles are dispersed throughout a liquid or gas and can settle over time.
