Question

4. A worker in a hardware store accidentally poured some steel nails

into a container of aluminum nails. All of the nails look exactly alike.
What would be the best way to separate the mixture of nails?
O A Heat the container until the aluminum nails melt.
B Use a hand lens to see the difference between the nails.
OC Pour water into the container to see which nails float.
OD Drag a magnet through the container to remove the iron nails.

Answer 1

D. Drag a magnet through the container to remove the iron nails.

Step-by-step explanation:

This is the best way to separate the mixture of nails because steel nails (also known as iron nails) are magnetic and will stick to the magnet, while aluminum nails are not magnetic and will remain in the container.
