Assuming the plumbing pipe is PVC, the answer would be nonmetal
PVC or polyvinyl chloride has a chemical formula of (C2H3Cl)n. From the element, we can see that the polyvinyl chloride is made from carbon, hydrogen, and chloride. There are no elements that belong to the metal group or metalloid group, so the plumbing pipe would be nonmetal.
The person above me is correct
A certain skin lotion is a fine mixture of water and various oils. This lotion is cloudy and cannot be separated into oil and water by any filtration or centrifuge, it is a colloid mixture. The colloid consists of large molecules & ultra microscopic particles of a substance that has been dispersed by another substance.
The term referring to that region would be "orbital".
