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.
A. H2O is the substance reduced.
H2O + 2e^(-) →H_2 + 2OH^(-)
The substance that gains electrons is reduced.
Remember OIL <em>RIG </em>(<em>R</em>eduction <em>I</em>s <em>G</em>ain of electrons) and
LEO the lion says <em>GER</em> (<em>G</em>ain of <em>E</em>lectrons is <em>R</em>eduction).
Building a space station in orbit is a safety measure. If a rocket fails to bring up the entire space station in one piece it would be extremely expensive to build a new one. Bringing it up in multiple places ensures less money would be lost if the rocket fails.
