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.

Answer:
14 mol O₂
Explanation:
The reaction between CO and O₂ is the following:
CO + O₂ → CO₂
We balance the equation with a coefficient 2 in CO and CO₂ to obtain the same number of O atoms:
2CO + O₂ → 2CO₂
As we can see from the balanced equation, 1 mol of O₂ is required to react with 2 moles of CO. Thus, the conversion factor is 1 mol of O₂/2 mol CO. We multiply the moles of CO by the conversion factor to calculate the moles of O₂ that are required:
28 mol CO x 1 mol of O₂/2 mol CO = 14 mol O₂
Atoms are combining to form molecules
Based upon Max Planck's theory of black-body radiation, Einstein theorized that the energy in each quantum of light was equal to the frequency multiplied by a constant, later called Planck's constant. A photon above a threshold frequency has the required energy to eject a single electron, creating the observed effect.
