I believe it might be A, hope this helps!
Answer:
A high pH value indicates a high concentration of OH- ion
Explanation:
The higher the OH- ion concentration high will be the pH.In simple words if the concentration of OH- ions are increased then the pH of the solution will also increase which means the solution will turns towards basic with increasing its OH- ion concentration.
Let us assume that the OH- concentration of a solution is 10-9 so the pOH of that solution will be 9 and the pH will be 5.
Now the concentration of OH-ion of that solution is increased from 10-9 to 10-8 now the pOH of that solution is 8 and the pH is 6.
A) Head to tail joining of monomers. :) (confirmed correct answer, I took the test)
has 37 electrons in the orbit about its nucleus.
<h3>How to write an atomic symbol with atomic mass and atomic number?</h3>
Atomic mass is the total number of neutrons and protons present in the nucleus of an element.
The atomic number is the total number of protons present in the nucleus of an element.
For writing an atomic symbol, atomic mass is written on the top left of the atomic symbol, and the atomic number is written on the downside of the left of the symbol.

An electrically neutral atom is an atom that has an equal number of electrons as well as protons.
Thus from the above conclusion we can say that
has 37 electrons.
